1.6 Safety
1.6.1 Summary of safety markings
These User Instructions contain specific safety
markings where non-observance of an instruction would
cause hazards. The specific safety markings are:
This symbol indicates electrical safety
instructions where non-compliance will involve a high
risk to personal safety or the loss of life.
This symbol indicates safety instructions where
non-compliance would affect personal safety and
could result in loss of life.
This symbol indicates “hazardous and toxic fluid”
safety instructions where non-compliance would affect
personal safety and could result in loss of life.
This symbol indicates safety
instructions where non-compliance will involve some
risk to safe operation and personal safety and would
damage the equipment or property.
This symbol indicates explosive atmosphere
zone marking according to ATEX. It is used in safety
instructions where non-compliance in the hazardous
area would cause the risk of an explosion.
1.6.3 Safety action
This is a summary of conditions and actions to
help prevent injury to personnel and damage to
the environment and to equipment. For products
used in potentially explosive atmospheres
section 1.6.4 also applies.
NEVER DO MAINTENANCE WORK
WHEN THE UNIT IS CONNECTED TO POWER
(Lock out.)
DRAIN THE PUMP AND ISOLATE PIPEWORK
BEFORE DISMANTLING THE PUMP
The appropriate safety precautions should be taken
where the pumped liquids are hazardous.
FLUOROELASTOMERS (When fitted.)
When a pump has experienced temperatures over
250 ºC (482 ºF), partial decomposition of
fluoroelastomers (example: Viton) will occur. In this
condition these are extremely dangerous and skin
contact must be avoided.
HANDLING COMPONENTS
Many precision parts have sharp corners and the
wearing of appropriate safety gloves and equipment
is required when handling these components. To lift
heavy pieces above 25 kg (55 lb) use a crane
appropriate for the mass and in accordance with
current local regulations.
This symbol is used in safety instructions to
remind not to rub non-metallic surfaces with a dry
cloth; ensure the cloth is damp. It is used in safety
instructions where non-compliance in the hazardous
area would cause the risk of an explosion.
This sign is not a safety symbol but indicates
an important instruction in the assembly process.
1.6.2 Personnel qualification and training
All personnel involved in the operation, installation,
inspection and maintenance of the unit must be
qualified to carry out the work involved. If the
personnel in question do not already possess the
necessary knowledge and skill, appropriate training
and instruction must be provided. If required the
operator may commission the manufacturer/supplier
to provide applicable training.
Always coordinate repair activity with operations and
health and safety personnel, and follow all plant
safety requirements and applicable safety and health
laws and regulations.
NEVER OPERATE THE PUMP WITHOUT THE
COUPLING GUARD AND ALL OTHER SAFETY
DEVICES CORRECTLY INSTALLED
GUARDS MUST NOT BE REMOVED WHILE
THE PUMP IS OPERATIONAL
THERMAL SHOCK
Rapid changes in the temperature of the liquid within
the pump can cause thermal shock, which can result
in damage or breakage of components and should be
avoided.
NEVER APPLY HEAT TO REMOVE IMPELLER
Trapped lubricant or vapor could cause an explosion.
HOT (and cold) PARTS
If hot or freezing components or auxiliary heating
equipment can present a danger to operators and
persons entering the immediate area, action must be
taken to avoid accidental contact (such as shielding). If
complete protection is not possible, the machine access
must be limited to maintenance staff only with clear
visual warnings and indicators to those entering the
Page 4
ESP3 USER INSTRUCTIONS ENGLISH 26999943 08-11
of 64
immediate area. Note: bearing housings must not be
insulated and drive motors and bearings may be hot.
If the temperature is greater than 80 °C (176°F) or
below -5 °C (23 °F) in a restricted zone, or
exceeds local regulations, action as above shall
be taken.
HAZARDOUS LIQUIDS
When the pump is handling hazardous liquids care
must be taken to avoid exposure to the liquid by
appropriate pump placement, limiting personnel
access and by operator training. If the liquid is
flammable and/or explosive, strict safety procedures
must be applied.
Gland packing must not be used when pumping
hazardous liquids.
PREVENT EXCESSIVE EXTERNAL
PIPE LOAD
Do not use pump as a support for piping. Do not
mount expansion joints, unless allowed by Flowserve
in writing, so that their force, due to internal pressure,
acts on the pump flange.
ENSURE CORRECT LUBRICATION
(See section 5, Commissioning, startup, operation and shutdown.)
NEVER EXCEED THE MAXIMUM
DESIGN PRESSURE (MDP) AT THE
TEMPERATURE SHOWN ON THE PUMP
NAMEPLATE
See section 3 for pressure versus temperature
ratings based on the material of construction.
NEVER OPERATE THE PUMP WITH
THE DISCHARGE VALVE CLOSED
(Unless otherwise instructed at a specific point in the
User Instructions)
(See section 5, Commissioning start-up, operation and shutdown.)
NEVER RUN THE PUMP DRY OR
WITHOUT PROPER PRIME (Casing flooded)
NEVER OPERATE THE PUMP WITH
THE SUCTION VALVE CLOSED
It should be fully opened when the pump is running.
NEVER OPERATE THE PUMP AT
ZERO FLOW OR FOR EXTENDED PERIODS
BELOW THE MINIMUM CONTINUOUS FLOW
THE PUMP SHAFT MUST TURN
CLOCKWISE WHEN VIEWED FROM THE MOTOR
END
It is absolutely essential that the rotation of the motor
be checked before installation of the coupling drive
element and starting the pump. Incorrect rotation of
the pump for even a short period can unscrew the
impeller, which can cause significant damage.
1.6.4 Products used in potentially explosive
atmospheres
Measures are required to:
• Avoid excess temperature
• Prevent buildup of explosive mixtures
• Prevent the generation of sparks
• Prevent leakages
• Maintain the pump to avoid hazard
The following instructions for pumps and pump units
when installed in potentially explosive atmospheres
must be followed to help ensure explosion protection.
Both electrical and non-electrical equipment must meet
the requirements of European Directive 94/9/EC.
1.6.4.1 Scope of compliance
Use equipment only in the zone for which it is
appropriate. Always check that the driver, drive
coupling assembly, seal and pump equipment are
suitably rated and/or certified for the classification of
the specific atmosphere in which they are to be
installed.
Where Flowserve has supplied only the bare shaft
pump, the Ex rating applies only to the pump. The
party responsible for assembling the pump set shall
select the coupling, driver, seal and any additional
equipment, with the necessary CE Certificate/
Declaration of Conformity establishing it is suitable for
the area in which it is to be installed.
The output from a variable frequency drive (VFD) can
cause additional heating affects in the motor. On
pump installations controlled by a VFD, the ATEX
Certification for the motor must state that it covers the
situation where electrical supply is from the VFD.
This particular requirement still applies even if the
VFD is in a safe area.

Pump liquid temperature
Pumps have a temperature class as stated in the ATEX
Ex rating on the nameplate. These are based on a
maximum ambient temperature of 40 ºC (104 ºF); refer
to Flowserve for higher ambient temperatures.
The surface temperature on the pump is influenced by
the temperature of the liquid handled. The maximum
permissible liquid temperature depends on the
temperature class and must not exceed the values in the
table applicable below.

The temperature rise at the seals and bearings and due
to the minimum permitted flow rate is taken into account
in the temperatures stated.
The responsibility for compliance with the specified
maximum liquid temperature is with the plant
operator.
Temperature classification “Tx” is used when the
liquid temperature varies and the pump could be
installed in different hazardous atmospheres. In this
case the user is responsible for ensuring that the
pump surface temperature does not exceed that
permitted in the particular hazardous atmosphere.
Do not attempt to check the direction of rotation with the
coupling element/pins fitted due to the risk of severe
contact between rotating and stationary components.
Where there is any risk of the pump being run against a
closed valve generating high liquid, casing and
discharge pipe external surface temperatures, fit an
external surface temperature protection device.
Avoid mechanical, hydraulic or electrical overload by
using motor overload trips, temperature monitor or a
power monitor and perform routine vibration monitoring.
In dirty or dusty environments, make regular checks
and remove dirt from areas around close clearances,
bearing housings and motors.
1.6.4.4 Preventing the buildup of explosive
mixtures
Page 6
ENSURE PUMP IS PROPERLY FILLED AND
VENTED AND DOES NOT RUN DRY
Ensure that the pump and relevant suction and discharge
piping is totally filled with liquid at all times during the
pumps operation so that an explosive atmosphere is
prevented. In addition, it is essential to make sure that
seal chambers, auxiliary shaft seal systems and any
heating and cooling systems are properly filled.
ESP3 USER INSTRUCTIONS ENGLISH 26999943 08-11
of 64
If the operation of the system cannot avoid this
condition, fit an appropriate dry run protection device
(for example liquid detection or a power monitor).
To avoid potential hazards from fugitive emissions of
vapor or gas to atmosphere, the surrounding area
must be well ventilated.
1.6.4.5 Preventing sparks
To prevent a potential hazard from mechanical
contact, the coupling guard must be non-sparking for
Category 2.
To avoid the potential hazard from random induced
current generating a spark, the baseplate must be
properly grounded.
Avoid electrostatic charge. Do not rub nonmetallic surfaces with a dry cloth; ensure the cloth is
damp.
The coupling must be selected to comply with
94/9/EC and correct alignment must be maintained.
Additional requirements for pumps on nonmetallic baseplates
When metallic components are fitted on a nonmetallic baseplate they must be individually earthed.
1.6.4.6 Preventing leakage
Pumps with mechanical seal: The pump must
only be used to handle liquids for which it has been
approved to have the correct corrosion resistance.
Avoid entrapment of liquid in the pump and associated
piping due to closing of suction and discharge valves,
which could cause dangerous excessive pressures to
occur if there is heat input to the liquid. This can occur if
the pump is stationary or running.
Bursting of liquid containing parts due to freezing
must be avoided by draining or protecting the pump
and auxiliary systems.
Where there is the potential hazard of a loss of a seal
barrier fluid or external flush, the fluid must be monitored.
If leakage of liquid to atmosphere can result in a
hazard, install a liquid detection device.
1.6.4.7 Maintenance of the centrifugal pump to
avoid a hazard
CORRECT MAINTENANCE IS REQUIRED TO
AVOID POTENTIAL HAZARDS WHICH GIVE A
RISK OF EXPLOSION
The responsibility for compliance with maintenance
instructions is with the plant operator.
To avoid potential explosion hazards during maintenance,
the tools, cleaning and painting materials used must not
give rise to sparking or adversely affect the ambient
conditions. Where there is a risk from such tools or
materials, maintenance must be conducted in a safe area.
It is recommended that a maintenance plan and schedule
is adopted. (See section 6, Maintenance.)

1.9 Noise level
Attention must be given to the exposure of personnel
to the noise, and local legislation will define when
guidance to personnel on noise limitation is required,
and when noise exposure reduction is mandatory.
This is typically 80 to 85 dBA.
The usual approach is to control the exposure time to
the noise or to enclose the machine to reduce emitted
sound. You may have already specified a limiting
noise level when the equipment was ordered,
however if no noise requirements were defined, then
attention is drawn to the following table to give an
indication of equipment noise level so that you can
take the appropriate action in your plant.
Pump noise level is dependent on a number of
operational factors, flow rate, pipe work design and
acoustic characteristics of the building, and so the
values given are subject to a 3 dBA tolerance and
cannot be guaranteed.
Similarly the motor noise assumed in the “pump and
and high efficiency motors when on load directly
driving the pump. Note that a motor driven by an
inverter may show an increased noise at some
speeds.
If a pump unit only has been purchased for fitting with
your own driver then the “pump only” noise levels in
the table should be combined with the level for the
driver obtained from the supplier. Consult Flowserve
or a noise specialist if assistance is required in
combining the values.
It is recommended that where exposure approaches
the prescribed limit, then site noise measurements
should be made.
The values are in sound pressure level LpA at 1 m
(3.3 ft) from the machine, for “free field conditions
over a reflecting plane”. The values are
representative of a non-submerged wet end.
For estimating sound power level LWA (re 1 pW) then
add 14 dBA to the sound pressure value.
motor” noise is that typically expected from standard
`1 The noise level of machines in this range will most likely be of values which require noise exposure control, but typical values are
inappropriate.
Note: for 1 180 and 960 r/min reduce 1 450 r/min values by 2 dBA. For 880 and 720 r/min reduce 1 450 r/min values by 3 dBA.

2 TRANSPORT AND STORAGE
2.1 Consignment receipt and unpacking
Immediately after receipt of the equipment it must be
checked against the delivery/shipping documents for
its completeness and that there has been no damage
in transportation. Any shortage and/or damage must
be reported immediately to Flowserve Pump Division
and must be received within ten days of receipt of the
equipment. Later claims cannot be accepted.
Check any crate, boxes or wrappings for any
accessories or spare parts that may be packed
separately with the equipment or attached to
sidewalls of the box or equipment.
Each product has a unique serial number. Check
that this number corresponds with that advised and
always quote this number in correspondence as well
as when ordering spare parts or further accessories.
2.2 Handling
Boxes, crates, pallets or cartons may be unloaded
using forklift vehicles or slings dependent on their
size and construction.
2.3 Lifting
Pumps and motors often have integral
lifting lugs or eye bolts. These are intended for use in
only lifting the individual piece of equipment.
Do not use or cast-in lifting lugs to lift
pump, motor and mounting plate assemblies.
Care must be taken to lift components
or assemblies above the center of gravity to prevent
the unit from flipping.
Carefully sling ESP pumps so that
bearing lubrication lines [3840.1] will not be bent or
damaged when lifting.
It is advisable to raise the pump into the vertical
position before uncrating. If this isn't possible, pumps
over eight feet long must be supported at more than
one place when raising to the vertical position. Use a
support strap around the bottom column [1341.2] and
on the motor support [3160]. Or lift use optionally
supplied lifting eyes [6820] installed on mounting
plate [6130].
2.4 Storage
Store the pump in a clean, dry location
away from vibration. Leave flange covers in place to
keep dirt and other foreign material out of pump
casing. Turn the pump shaft at regular intervals to
prevent brinelling of the bearings and the seal faces,
if fitted, from sticking.
The pump may be stored as above for up to 6
months. Consult Flowserve for preservative actions
when a longer storage period is needed.
2.4.1 Short term storage and packaging
Normal packaging is designed to protect the pump
and parts during shipment and for dry, indoor storage
for up to six months or less. The following is an
overview of our normal packaging:
•All loose un-mounted items are packaged in a
water proof plastic bag and secured to the pallet.
•Inner surfaces of the bearing housing, shaft (area
through bearing housing) and bearings are coated
with Cortec VCI-329 rust inhibitor, or equal.
Bearing housings are not filled with oil
prior to shipment
• Regreasable bearings are packed with grease
• The internal surfaces of ferrous casings, covers,
flange faces, and the impeller surface are
sprayed with Cortec VCI-389, or equal
• Exposed shafts are taped with Polywrap
• Flange covers are secured to both the suction
and discharge flanges
•In some cases with assemblies ordered with
external piping, components may be
disassembled for shipment
•The pump must be stored in a covered, dry
location
2.4.2 Long term storage and packaging
Long term storage is defined as more than six
months, but less than 12 months. The procedure
Flowserve follows for long term storage of pumps is
given below. These procedures are in addition to the
short term procedure.
•Each assembly is hermetically (heat) sealed from
the atmosphere by means of tack wrap sheeting
and rubber bushings (mounting holes)
•Desiccant bags are placed inside the tack
wrapped packaging
•A solid wood box is used to cover the assembly
This packaging will provide protection for up to twelve
months from humidity, salt laden air, dust etc.
Page 9
ESP3 USER INSTRUCTIONS ENGLISH 26999943 08-11
of 64
After unpacking, protection will be the responsibility of
the user. If units are to be idle for extended periods
after addition of lubricants, inhibitor oils and greases
should be used. Every three months, the pump shaft
should be rotated approximately 10 revolutions.
2.5 Recycling and end of product life
At the end of the service life of the product or its
parts, the relevant materials and parts should be
recycled or disposed of using an environmentally
acceptable method and in accordance with local
regulations. If the product contains substances that
are harmful to the environment, these should be
removed and disposed of in accordance with current
local regulations. This also includes the liquids
and/or gases that may be used in the "seal system"
or other utilities.
Make sure that hazardous substances are
disposed of safely and that the correct personal
protective equipment is used. The safety
specifications must be in accordance with the current
local regulations at all times.

3.3 Design of major parts
3.3.1 Pump casing
As used by the Mark 3 Product Line. Depending upon
the installation, the casing feet may have been
removed. Axial bolting retains the casing to the cover
and compresses the sealing gasket.
3.3.2 Impeller
Depending on the product, the impeller is either reverse
vane or open. The impeller is threaded to the end of the
shaft
3.3.3 Shaft/sleeve
Solid and sleeved shafts are available. The shaft is
threaded on the impeller end and keyed on the drive
end.
3.3.4 Pump bearings and lubrication
The external thrust bearing is a grease-lubricated
duplex angular contact ball bearing. The radial load
line bearings are sleeve plain bearings lubricated by
product, external flush or grease.
3.3.5 Bearing housing
The external housing contains grease ports and is
sealed with lip seals.
3.3.6 Cover plate
The cover plate has a spigot (rabbet) fit between the
pump casing and adapter for optimum concentricity.
The cover plate holds the throttle bushing at the back

a) The correct pressure-temperature chart is Figure
3-4.
b) From Figure 3-3, the correct material group for
CF8M is 2.2
c) From Figure 3-4, the pressure-temperature rating
is 14.8 bar.
The maximum discharge pressure must be less
than or equal to the P-T rating. Discharge pressure
may be approximated by adding the suction pressure
and the differential head developed by the pump.
3.4.3 Suction pressure limits
Pump suction pressure is limited by the maximum pump
length and the maximum sump pressure of 3.45 bar (50
psi).
3.4.4 Minimum continuous flow
The minimum continuous flow (MCF) is based on a
percentage of the best efficiency point (BEP).
Figure 3-2 identifies the MCF for all ESP3 pump
models with the exception of the Lo-Flo pump line;
there is no MCF associated with this product line.

of 64
4.1 Location
The pump should be located to allow room for
installation, access, ventilation, maintenance, and
inspection with ample headroom for lifting. Refer to
the general arrangement drawing for the pump set.
If pump is furnished with external flush-lubricated
bearings, the fluid lines must be accessible from
the pump location.
Also important, especially in the larger flow units, is
proper sump design. Liquid velocity approaching
the pump should be one foot per second or less.
When more than one pump is installed and used at
the same time in the same sump, the location and
spacing of the pumps are important. The
guidelines for sump design and pump placement as
outlined in the "Hydraulic Institute Standards" are
recommended.
4.2 Part assemblies
•Pumps are shipped completely assembled
except for driver, strainer [6531], float controls
(if furnished), pit cover, and the mechanical
seal [4200] or packing [4130] for the stuffing
box on a vapor proof or pressurized design
pump.
•When mechanical seals are furnished, they
should be installed before the motor is put in
place. Refer to seal installation instructions in
section 6.9.5.
•Vapor Proof and Pressurized design pumps
are furnished with an upper stuffing box
[4110]. If the stuffing box doesn't already have
the packing [4130] or seal [4200] installed,
then they should be installed before the motor
is mounted. See section 6.
•The driver will be mounted after the pump is
installed.
•When the pump is shipped, all threads and all
openings are covered. This protection should
not be removed until installation. If the pump
is removed from service, this protection should
be reinstalled.
4.3 Foundation
There should be adequate space for workers to
install, operate, and maintain the pump. The
foundation should be sufficient to absorb any
vibration and should provide a rigid support for the
pump and motor. Recommended mass of a
concrete foundation should be three times that of
the pump, motor and mounting plate. Supporting
members must be sufficiently strong to prevent
spring action and/or lateral movement.
4.4 Pump Mounting
The pump may be mounted directly on the pit
using the pump mounting plate [6130] or in
conjunction with a pit cover.
a) The pump was checked during assembly at
the factory to make sure the pump shaft [2100]
rotated freely by hand. Handling during
shipment, storage, or preparation for
installation could have caused distortions
resulting in pump shaft binding. Check the
shaft to make sure that it will rotate freely by
hand.
b) Check all bolts and nuts for tightness, then
carefully lower the assembled pump into the
pit, taking care not to damage lube lines or float
control equipment. Make sure that any
equipment used to lift the pump or any of
its components is capable of supporting the
weights encountered. Make sure that all parts
are properly rigged before attempting to lift.
c) Pump mounting plate and/or pit cover must
maintain level within 1/8in/ft. from one side of
the plate to the other, and be supported evenly
at all points before being bolted down.
d) If the sump doesn't provide a level mounting
surface for the pump, drive wedges under
the mounting plate/pit cover until pump levels
out. The wedges must be able to support the
weight of the entire pumping assembly and
hold the assembly steady enough that no
excess vibration occurs.
e) Do not bolt the discharge flange of the pump
to the piping until the baseplate foundation is
completely installed.
f) Run piping to the discharge of the pump.
There should be no piping loads transmitted to
the pump after connection is made.
4.5 Mechanical seals and packing
Pumps supplied with vapor proof construction or
pressurized designs are furnished with an upper
stuffing box [4110] equipped to take mechanical
seals or packing (see vapor proof and pressurized
design cross-sections in section 8). Gas seals are
typically of a canister design, thus the stuffing box
is omitted. The canister seals are mounted directly
to the upper column [1341.1]. Installation
instructions can be found in section 6.9.5
4.5.1 Mechanical seal
Mechanical seals [4200] are typically installed prior
to shipment. Specific order requirements may
specify that the seal be shipped separately, or none
be supplied. It is the pump installer’s responsibility
to determine if a seal was installed. Installation
instruction can be found in section 6
Page 18
of 64
Failure to ensure that a seal is installed may
result in serious leakage of vapor and of the pumped
fluid.
Seal and seal support system must be installed and
operational as specified by the seal manufacturer.
The stuffing box/seal chamber/gland may have
ports that have been temporarily plugged at the
factory to keep out foreign matter. It is the
installer’s responsibility to determine if these plugs
should be removed and external piping connected.
Refer to the seal drawings and or the local
Flowserve representative for the proper
connections.
4.5.2 Packing
When the pump is intended to be equipped with
shaft packing, it is NOT Flowserve standard
practice to install the packing in the stuffing box
prior to shipment. The packing is shipped with the
pump. It is the pump installer’s responsibility to
install the packing in the stuffing box. Installation
instructions can be found in section 6.
Failure to ensure that the packing is installed
may result in serious leakage of vapor and of the
pumped fluid.
4.6 Driver Mounting
a) Before the motor is installed, be sure to
connect the motor half coupling hub and the
pump half coupling hub onto their respective
shafts.
b) Carefully lift the motor and place it on the
support head [3160] of the pump.
c) Turn the motor frame to one of the four
positions where the motor bolt holes line up to
the support head [3160]. Select the position of
the motor to suit the desired conduit box
location. Install the motor hold down bolts
[6570.1]. In some instances a motor adapter
[1340.3] may be furnished. In this case the
adapter must be installed before the motor can
be mounted.
d) Motor to pump alignment is controlled by fits
within the adapter and cannot be adjusted.
e) Locate the coupling and source of electrical
power but DO NOT INSTALL THE COUPLING
DRIVE ELEMENT AT THIS TIME.
f) Connect the motor terminals to the leads from
the starter panel. Make sure the motor shaft
and/or coupling is not touching any part of the
pump shaft or pump half coupling. Rotate the
ESP3 USER INSTRUCTIONS ENGLISH 26999943 08-11
motor shaft by hand to make sure it is free to
rotate when energized.
Never check driver rotation unless the
pump and driver shafts are disconnected and
physically separated. Failure to follow this
instruction can result in serious damage to the
pump and driver if rotation is in the wrong
direction.
g) Jog the motor and check for proper rotation
which should be clockwise when looking
down on top of the motor. If rotation is wrong,
interchange any two motor connections on
three-phase motors. On single-phase motors,
follow the motor manufacturer’s instructions. After
changing the connections, again check the rotation
to ensure that the direction is correct.
h) Disconnect and lockout the power supply to the
driver.
i) The coupling can now be fully installed and
join the driver and pump shafts together (see
section 5.4.2).
j) Install the coupling guarding [7450.1-.2] (see
section 5.5).
4.7 Piping
Protective covers are fitted to both the
suction and discharge flanges of the casing and must
be removed prior to connecting the pump to any
pipes.
4.7.1 General piping
If the pump flange(s) have tapped holes, select flange
fasteners with thread engagement at least equal to
the fastener diameter but that do not bottom out in the
tapped holes before the joint is tight.
4.7.2 Suction piping
ESP pumps typically only have strainers attached to
the suction flange of the pump casing. An option for
an extension from the suction flange is available and
is called a tailpipe (see section 8 for cross-sectional
drawing). A tailpipe is useful for applications where
there is adequate NPSH at the lowest sump level but
the discharge pressure is critical and must be
maintained at a maximum value compared to using a
longer column and shaft. Pumps may air-bind if air is
allowed to leak into the piping
Page 19
ESP3 USER INSTRUCTIONS ENGLISH 26999943 08-11
of 64
4.7.3 Discharge piping
Install a valve in the discharge line. This valve is
required for regulating flow and/or to isolate the
pump for inspection and maintenance.
When fluid velocity in the pipe is
high, for example, 3 m/s (10 ft/sec) or higher, a
rapidly closing discharge valve can cause a
damaging pressure surge. A dampening
arrangement should be provided in the piping.
All piping must be independently supported,
accurately aligned and preferably connected to the
pump by a short length of flexible piping. The pump
should not have to support the weight of the pipe. It
should be possible to install discharge bolts through
mating flanges without pulling or prying either of the
flanges. All piping must be tight.
a) Use discharge piping one size larger than the
pump discharge.
b) Discharge piping should be well supported
and connected to the pump such that no strain
or weight of the piping is carried by the pump.
c) Check pump shaft for freedom of rotation by
hand to make sure any discharge piping strain
is not causing binding.
d) After the pump discharge, the increaser
should be the first item in the discharge line,
followed by the check valve and gate valve,
respectively. See Figure 4-1.
e) It is recommended that pressure indicating
devices be installed before and after the
valves in the discharge line to verify the pump
is not being run dry and that the discharge
valves are not closed.

4.7.4 Allowable Nozzle Loads
Discharge piping should be constructed to fit to the
ESP3 discharge piping flange. The ESP3 design
can accommodate large piping loads without
installation should not impose unnecessary loads to
the discharge flange. The allowable piping loads

4.8 Final free rotation check
After connecting the piping, rotate the pump drive
shaft clockwise (viewed from motor end) by hand
several complete revolutions to be sure there is no
binding and that all parts are free. If piping caused
unit to be in a bind, correct piping to relieve strain
on the pump.
4.9 Auxiliary piping
Check to see if any other connections need to be
made to pump, such as fluid injection to stuffing
box for seal or packing lubrication (when furnished)
and make the required connections.
Check to see that connections are made to the
lubrication fittings at pump manifold [3869] on
mounting plate [6130]
4.10 Electrical connections
Electrical connections must be made
by a qualified Electrician in accordance with
relevant local national and international regulations.
It is important to be aware of the EUROPEAN
DIRECTIVE on potentially explosive areas where
compliance with IEC60079-14 is an additional
requirement for making electrical connections.
4.11 Level controls
Assemble float control equipment per Figure 4-3
below. Wire the float controls following the
diagrams on the next several pages. The stops
should be set in accordance with maximum and
minimum liquid levels desired and required. Float
rods are furnished in kits of a standard length. The
rod might have to be cut off to fit the particular
installation.
Figure 4-3
It is important to be aware of the EUROPEAN
DIRECTIVE on electromagnetic compatibility when
wiring up and installing equipment on site.
Attention must be paid to ensure that the techniques
used during wiring/installation do not increase
electromagnetic emissions or decrease the
electromagnetic immunity of the equipment, wiring or
any connected devices. If in any doubt contact
Flowserve for advice.
The motor must be wired up in
accordance with the motor manufacturer's
instructions (normally supplied within the terminal
box) including any temperature, earth leakage,
current and other protective devices as appropriate.
The identification nameplate should be checked to
ensure the power supply is appropriate.
See section 5.4, Direction of rotation
before connecting the motor to the electrical supply.
Some of the wiring diagrams are included on the
following pages. If the wiring diagram needed is not
included, contact control manufacturer for wiring

4.12 Protection systems
The following protection systems are
recommended particularly if the pump is installed in a
potentially explosive area or is handling a hazardous
liquid. If in doubt consult Flowserve.
If there is any possibility of the system allowing the
pump to run against a closed valve or below
minimum continuous safe flow a protection device
should be installed to ensure the temperature of the
liquid does not rise to an unsafe level.
If there are any circumstances in which the system
can allow the pump to run dry, or start up empty, a
power monitor should be fitted to stop the pump or
prevent it from being started. This is particularly
relevant if the pump is handling a flammable liquid.
If leakage of product from the pump or its associated
sealing system can cause a hazard it is
recommended that an appropriate leakage detection
system is installed.
To prevent excessive surface temperatures at
bearings it is recommended that temperature or
vibration monitoring is carried out.
5 COMMISSIONING, STARTUP,
OPERATION AND SHUTDOWN
These operations must be carried
out by fully qualified personnel.
5.1 Pre-commissioning procedure
5.1.1 Pre start-up checks
Prior to starting the pump it is essential that the
following checks be made. These checks are all
described in detail in the Maintenance section of this
manual.
• Motor properly secured to the support head
• All fasteners tightened to the correct torque
• Coupling guard in place and not rubbing
• Rotation check, see section 5.4.
This is absolutely essential
• Impeller clearance setting
• Shaft seal properly installed
• Seal support system operational
• Bearing lubrication
• Pump instrumentation is operational
• Rotation of shaft by hand
As a final step in preparation for operation, it is
important to rotate the shaft by hand to be certain that
all rotating parts move freely, and that there are no
foreign objects in the pump casing.
5.2 Bearing Lubrication
Two types of bearings are used in the ESP3. Line
shaft bearings are used to support pump shaft within
the column. These plain bearings are lubricated by
external flush, product lubrication or grease. Duplex
angular contact bearings are used to support the
coupling end of the shaft. These ball bearings
support coupling loads and pump thrust. They are
lubricated by bearing grease. See (5.2.3)
Operation of the unit without proper
lubrication can result in bearing failures, pump
seizures and pump failure.
5.2.1 Line Shaft Bearings
Check to see that no damage has occurred to any
lubrication lines above the mounting plate [6130]
during shipment or installation. For number of
bearings, refer to Figure 5-6. Check to see that
connections are made to lubrication fittings at pump
manifold [3869] on mounting plate [6130].
5.2.1.1 External Flush Lubrication
a) Clean liquid from an external source must be
used when pumps are furnished with external
flush lubrication connections. Liquid is typically
supplied continuously during operation. Some
bearings (such as carbon) can run without
lubrication for short periods but lubrication is
needed to dissipate heat and abrasives.
b) Check to see that connections are made to
lubrication fittings on pump manifold [3869] on
mounting plate [6130] and that 1.9 LPM (0.5
gpm) of flushing fluid per bearing, 3.0 LPM (0.8
gpm) for Group 3, (See Figure 5-6) at 1.4 kg/cm2
to 5.6 kg/cm2 (20 PSIG to 80 PSIG) above sump
pressure.
It is absolutely necessary that rubber
bearings be wet at all times during operation.
5.2.1.2 Product Lubrication
When conditions warrant, the pump can be furnished
with provisions for pumped product bearing
lubrication. This is accomplished by means of a
lubrication line from the discharge flange of the pump
casing [1100] to the adapter bearing [3020.2], while
the rest of the lines are run from the manifold [3869]
on the pump mounting plate [6130]. In the case of a
pumped-product lubricated pump with separators
furnished, all lube lines will be run from the pump
manifold [3869].

a) Check to see that connections are made to
lubrication fittings at pump manifold [3869] on
mounting plate [6130] and for the adapter
[1340.1] bearing [3020.2].
b) Check that 1.9 LPM (0.5 gpm), 3.0 LPM (0.8
gpm) for Group 3, of pumped liquid per bearing
(See Figure 5-5) at 1.4 kg/cm2 (20 PSIG) for
standard product lubricated pumps or 1.8 kg/cm2
(25 PSIG) for product lubricated pumps with
separators is available.
c) Changes in noise and vibration may indicate
insufficient lubrication.
5.2.1.3 Grease Lubrication
Pumps furnished with grease-lubricated shaft
bearings [3020.1-.2] will leave the factory with lube
lines [3840.1] and bearings [3020.1-.2] already
packed with grease. The grease used will be of a
water-resistant nature. Each bearing should be regreased prior to start-up through the grease fittings
located in the manifold [3869] on the pump mounting
plate [6130]. Grease must be insoluble in the liquid
being pumped. The recommended grease to be used
is Mobil Polyrex EP 2 or an equivalent. Bearing
lubrication lines are filled with Polyrex EP 2 before
the pump leaves the factory. Consult local lubricant
suppliers for the type of grease most compatible with
the liquid being pumped. The grease lubrication
system is the same as the external flush system with
the exception of the manifold [3869]. For grease
lubrication the manifold contains grease fittings while
the external flush manifold contains fluid line taps.
Grease lubricated line bearings require frequent
lubrication. Grease lubricating systems may be
utilized. Follow the manufacturer’s instruction for
proper use. Lubrication intervals and amounts can
be found in Figures 5-2 and 5-3.
Flowserve offers two lubrication systems that
significantly extend the line shaft bearing lubrication
intervals. Individual 2 oz. grease cups per line shaft
bearing and a fully automated progressive lubrication
system. Consult your Flowserve representative for
additional information.
5.2.2 Thrust Bearing
The external duplex angular contact thrust bearing
[3031] may be lubricated through the grease fitting
[3853.2]. Lubrication type, intervals and amount may
be found in Figures 5-1, 5-4 and 5-5. The bearing will
leave the factory with grease already packed.
A greased for-life option may be selected. In this
case, NYLOS® rings will be added to control grease
movement and the grease port will be plugged. A
shielded bearing will not need to be re-greased, but
will need to be replaced when it becomes excessively
worn.
Grease for life bearings
The replacement interval for these bearings is greatly
affected by their operating temperature and speed.
5.2.3 Driver Bearings
Driver Bearings should be re-greased before starting
the pump. Consult the manufacturer's directions for
lubricating instructions.

5.3 Impeller clearance
The impeller clearance was set at the factory. For
reverse-vane and recessed impellers, the clearance
is set to the cover while the open impeller clearance
is set to the casing
The impeller setting may be checked or change due
to wear. See Section 6.6.
5.4 Direction of rotation
5.4.1 Rotation check
It is absolutely essential that the rotation of the
motor be checked before installing the coupling drive
element. Incorrect rotation of the pump, for even a
short time, can dislodge and damage the impeller,
casing, shaft and shaft seal. All ESP3 3 pumps turn
clockwise as viewed from the motor end (top). A
direction arrow is cast on the support head [3160].
5.4.2 Coupling installation
Turn off the driver power and lock it
out so that the driver cannot be started during the
coupling assembly. Non-spacer couplings are used.
Mount coupling hubs/sheaves on pump and motor
shafts prior to attaching motor to the support head.
The coupling should be installed as
advised by the coupling manufacturer. Pumps are
shipped without the sleeve installed. If the sleeve
has been installed then it must be removed prior to
checking rotation. Remove all protective material
from the coupling and shaft before installing the
coupling.
5.5 Guarding
Power must never be applied to the driver when
the coupling guard is not installed.
In member countries of the EU and EFTA, it
is a legal requirement that fasteners for guards must
remain captive in the guard to comply with the
Machinery Directive 2006/42/EC. When releasing
such guards, the fasteners must be unscrewed in an
appropriate way to ensure that the fasteners remain
captive.
Flowserve coupling guards are safety devices intended
to protect workers from inherent dangers of the rotating
pump shaft, motor shaft and coupling. It is intended to
prevent entry of hands, fingers or other body parts into a
point of hazard by reaching through, over, under or
around the guard. No standard coupling guard provides
complete protection from a disintegrating coupling.
Flowserve cannot guarantee their guards will
completely contain an exploding coupling.
5.6 Priming and auxiliary supplies
A pump is said to be “primed” when the casing is
submerged and completely filled with liquid. Open
discharge valves a slight amount. This will allow any
entrapped air to escape and will normally allow the
pump to prime, if the liquid level is above the pump
casing. When a condition exists where the suction
pressure may drop below the pump’s capability, it is
advisable to add a low-pressure control device to shut
the pump down when the pressure drops below a
predetermined minimum.
Depending upon the bearing lubrication and shaft
seal option, some auxiliary supply lines may need to
be brought to the pump. Check to see if any other
connections need to be made to pump, such as fluid
injection to stuffing box for seal or packing lubrication
(when furnished) and make the required connections.
Check to see that connections are made to the
lubrication fittings at pump manifold [3869] on
mounting plate [6130]
Seals must never be run without
lubrication. Abrasive lubrication will greatly reduce
seal life.
5.7 Starting the pump
To avoid pump damage or injury to operating
personnel during start-up and operation:
•DO NOT operate the pump outside of design
parameters.
•DO NOT run with a closed discharge for more than
one minute.
•DO NOT operate with safety devices (i.e. coupling
guard) removed.
•DO NOT run the pump dry.
a) Ensure the pump is primed. (See section 5.6.)
The sump liquid level must cover the casing and
adapter. Minimum submergence number can be
found in Figure 3-6.
b) All flush lines must be started and regulated.
c) Start the driver (typically, the electric motor).
d) Slowly open the discharge valve until the desired
flow is reached, keeping in mind the minimum
continuous flow listed in Figure 3-2.
e) Check all joints and mechanical seal (if
furnished) for leakage.
f) If packing is furnished, adjust the packing gland
and flush flow.
g) Check for excessive vibration.
h) Monitor bearing temperature until it stabilizes.
Page 34
ESP3 USER INSTRUCTIONS ENGLISH 26999943 08-11
of 64
It is important that the discharge valve be opened
within a short interval after starting the driver. Failure to
do this could cause a dangerous buildup of heat, and
possibly an explosion.
5.8 Running or operation
5.8.1 Minimum continuous flow
Minimum continuous stable flow is the lowest flow at
which the pump can operate and still meet the bearing
life, shaft deflection and bearing housing vibration limits
documented in the latest version of ASME B73.1M.
Pumps may be operated at lower flows, but it must be
recognized that the pump may exceed one or more of
these limits. For example, vibration may exceed the
limit set by the ASME standard. The size of the pump,
the energy absorbed, and the liquid pumped are some
of the considerations in determining the minimum
continuous flow (MCF).
The minimum continuous flow (capacity) is established
as a percentage of the best efficiency point (BEP). (See
section 3.4.4.)
5.8.2 Minimum thermal flow
All ESP3 pumps also have a minimum thermal flow.
This is defined as the minimum flow that will not
cause an excessive temperature rise. Minimum
thermal flow is application dependent.
Do not operate the pump below
minimum thermal flow, as this could cause an excessive
temperature rise. Contact a Flowserve sales engineer
for determination of minimum thermal flow.
Avoid running a centrifugal pump at drastically reduced
capacities or with discharge valve closed for extended
periods of time. This can cause severe temperature
rise and the liquid in the pump may reach its boiling
point. If this occurs, the bearings and any equipment
flushed with process fluid will be exposed to vapor, with
no lubrication, and may score or seize to the stationary
parts.
Thermostats may be used to safeguard against
overheating by shutting down the pump at a
predetermined temperature.
Safeguards should also be taken against possible
operation with a closed discharge valve, such as
installing a bypass back to the suction source. The size
of the bypass line and the required bypass flow rate is a
function of the input horsepower and the allowable
temperature rise.
5.8.3 Reduced head
Note that when discharge head drops, the pump’s
flow rate usually increases rapidly. Check motor for
temperature rise as this may cause overload. If
overloading occurs, throttle the discharge.
5.8.4 Surging condition
A rapidly closing discharge valve can cause a
damaging pressure surge. A dampening
arrangement should be provided in the piping.
5.8.5 Operation in sub-freezing conditions
When using the pump in sub-freezing conditions
where the pump is periodically idle, the sump should
be properly drained or protected with thermal devices
which will keep the liquid in the sump from freezing.
External bearing and seal lubrication lines must be
protected with thermal devices. High chrome iron
pumps are not recommended for applications below 18 °C (0 °F).
5.8.6 Operating Checks
Costly shutdowns will be avoided by making routine
checks on pump operation.
a) Check to see if liquid is being discharged. A
discharge pressure gauge is an easy way to
check whether or not the liquid is being pumped.
If, at any time, the gauge should drop near or to
zero, or register an abnormally high pressure,
shut down the pump immediately.
b) Observe pump for any abnormal noise or
vibration. Especially check for any CHANGE in
pump noise or vibration.
c) Bearing lubricating liquid, and sealing and
cooling liquid flows, should be checked
frequently.
5.8.7 Normal vibration levels, alarm and trip
Alarm and trip values for installed pumps should be
based on the actual measurements (N) taken on site
on the motors of vertical pumps in fully commissioned
as new condition. The example (N) value is given for
the preferred operating flow region (typically this may
extend to 70 to 120% of the pump best efficiency
point); outside the preferred flow region the actual
vibration experienced may be multiplied by up to two.
These standard values can vary with the rotational
speed and the power absorbed by the pump. For
any special case, contact your nearest Flowserve
office.

5.9 Stopping and shutdown
5.9.1 Shutdown considerations
When the pump is being shutdown, the procedure
should be the reverse of the start-up procedure.
First, slowly close the discharge valve and shut down
the driver.
The pump should be brought to zero
speed rapidly, especially on pumps equipped with
product-lubricated bearings.
Pumps driven by electric motors do not require any
special shutdown procedure. If turbine drive is used,
the operator must manually trip the over speed trip to
obtain rapid shutdown
5.10 Hydraulic, mechanical and electrical
duty
5.10.1 Net positive suction head (NPSH)
Net positive suction head - available (NPSHA) is the
measure of the energy in a liquid above the vapor
pressure. It is used to determine the likelihood that a
fluid will vaporize in the pump. It is critical because a
centrifugal pump is designed to pump a liquid, not a
vapor. Vaporization in a pump will result in damage to
the pump, deterioration of the Total differential head
(TDH), and possibly a complete stopping of pumping.
Net positive suction head - required (NPSHR) is the
decrease of fluid energy between the inlet of the
pump, and the point of lowest pressure in the pump.
This decrease occurs because of friction losses and
fluid accelerations in the inlet region of the pump and
particularly accelerations as the fluid enters the
impeller vanes. The value for NPSHR for the specific
pump purchased is given in the pump data sheet,
and on the pump performance curve.
For a pump to operate properly the NPSHA must be
greater than the NPSHR. Good practice dictates that
this margin should be at least 1.5 m (5 ft) or 20%,
whichever is greater.
Ensuring that NPSHA is larger than
NPSHR by the suggested margin will greatly enhance
pump performance and reliability. It will also reduce
the likelihood of cavitation, which can severely
damage the pump.
5.10.2 Specific gravity (SG)
Pump capacity and total head in meters (feet) of
liquid do not change with SG; however pressure
displayed on a pressure gauge is directly proportional
to SG. Power absorbed is also directly proportional
to SG. It is therefore important to check that any
change in SG will not overload the pump driver or
over pressurize the pump.
5.10.3 Viscosity
For a given flow rate the total head reduces with
increased viscosity and increases with reduced
viscosity. Also for a given flow rate the power
absorbed increases with the increased viscosity, and
reduces with reduced viscosity. Product lubricated
bearings require a minimum of viscosity of 0.4 cP;
>0.6 cP is recommended for extended bearing life.
Failure to maintain sufficient viscosity will result in a
damaged shaft and bearings, and possibly a complete
stopping of pumping. It is important that checks are
made with your nearest Flowserve office if changes
in viscosity are planned.
5.10.4 Pump speed
Changing the pump speed affects flow, total head,
power absorbed, NPSHR, noise and vibration levels.
Flow varies in direct proportion to pump speed. Head
varies as speed ratio squared. Power varies as speed
ratio cubed. If increasing speed it is important to ensure
the maximum pump working pressure is not exceeded,
the driver is not overloaded, NPSHA > NPSHR and that
noise and vibration are within local requirements and
regulations.
The number of line shaft bearings (bearing spans) has
been selected based upon the motor speed. These
spans impact the stability of the shaft and determine it
natural frequencies. The number of line shaft bearings
can be found in Figure 5-6. The bearing spans and
critical speeds can be found in Figure 3-8. The pump
should not be operated above it designed operating
speed as this may result in severe and damaging
vibration.
The minimum speed for pump with product lube
bearings is dictated by the ability of the discharge
pressure to deliver lube to the bearings. Pumps with
product lube line shaft bearings should not be operated
at speeds that deliver less than 20 PSIG at the
mounting plate or 25 PSIG if equipped with
separator(s).
Page 36
ESP3 USER INSTRUCTIONS ENGLISH 26999943 08-11
of 64
5.10.5 Minimum submergence
Each ESP3 pump has a minimum submergence
depending on the design conditions of that pump.
See Figure 3-6 to determine the minimum
submergence based upon pump flow and suction
size. All minimum submergence values are taken
from the bottom of the strainer.
If a tailpipe [1428] is used, the sump
(pit) liquid level must engulf the casing and adapter
completely during start-up.
6 MAINTENANCE
It is the plant operator's responsibility to ensure
that all maintenance, inspection and assembly work
is carried out by authorized and qualified personnel
who have adequately familiarized themselves with
the subject matter by studying this manual in detail.
(See also section 1.6.)
Any work on the machine must be performed when it
is at a standstill. It is imperative that the procedure
for shutting down the machine is followed, as
described in section 5.9.
On completion of work all guards and safety devices
must be re-installed and made operative again.
Before restarting the machine, the relevant
instructions listed in section 5, Commissioning, start up, operation and shut down must be observed.
Oil and grease leaks may make the ground
slippery. Machine maintenance must always
begin and finish by cleaning the ground and the
exterior of the machine.
If platforms, stairs and guardrails are required for
maintenance, they must be placed for easy access to
areas where maintenance and inspection are to be
carried out. The positioning of these accessories
must not limit access or hinder the lifting of the part to
be serviced.
When air or compressed inert gas is used in the
maintenance process, the operator and anyone in the
vicinity must be careful and have the appropriate
protection.
Do not spray air or compressed inert gas on skin.
Do not direct an air or gas jet towards other people.
Never use air or compressed inert gas to clean
clothes.
Before working on the pump, take measures to
prevent the pump from being accidentally started.
Place a warning sign on the starting device:
"Machine under repair: do not start."
With electric drive equipment, lock the main switch
open and withdraw any fuses. Put a warning sign on
the fuse box or main switch:
"Machine under repair: do not connect."
Never clean equipment with flammable solvents or
carbon tetrachloride. Protect yourself against toxic
fumes when using cleaning agents.
Refer to the parts list shown in section 8 for item
number references used throughout this section.
6.1 Maintenance schedule
It is recommended that a maintenance plan and
schedule be implemented, in accordance with these
User Instructions, to include the following:
a) Any auxiliary systems installed must be monitored,
if necessary, to ensure they function correctly.
b) Gland packing must be adjusted correctly to give
visible leakage and concentric alignment of the
gland follower to prevent excessive temperature
of the packing or follower.
c) Check for any leaks from gaskets and seals. The
correct functioning of the shaft seal must be
checked regularly.
d) Check bearing lubricant level, and the remaining
hours before a lubricant change is required.
e) Check that the duty condition is in the safe
operating range for the pump.
f) Check vibration, noise level and surface
temperature at the bearings to confirm
satisfactory operation.
g) Check dirt and dust is removed from areas
around close clearances, bearing housings and
motors.
6.1.1 Preventive maintenance
The following sections of this manual give
instructions on how to perform a complete
maintenance overhaul. However, it is also important
to periodically repeat the Pre start-up checks listed in
section 5.1. These checks will help extend pump life
as well as the length of time between major
overhauls.
6.1.2 Need for maintenance records
A procedure for keeping accurate maintenance
records is a critical part of any program to improve
pump reliability. There are many variables that can
contribute to pump failures. Often long term and
repetitive problems can only be solved by analyzing
these variables through pump maintenance records.
Page 37
ESP3 USER INSTRUCTIONS ENGLISH 26999943 08-11
of 64
6.1.3 Cleanliness
One of the major causes of pump failure is the
presence of contaminants in the bearing housing.
This contamination can be in the form of moisture,
dust, dirt and other solid particles such as metal
chips. Contamination can also be harmful to the
mechanical seal (especially the seal faces) as well as
other parts of the pump. For example, dirt in the
impeller threads could cause the impeller to not be
seated properly against the shaft. This, in turn, could
cause a series of other problems. For these reasons,
it is very important that proper cleanliness be
maintained. Some guidelines are listed below.
•After draining the oil from the bearing housing,
periodically send it out for analysis. If it is
contaminated, determine the cause and correct.
•The work area should be clean and free from
dust, dirt, oil, grease etc.
• Hands and gloves should be clean.
• Only clean towels, rags and tools should be
used.
6.2 Spare parts
The decision on what spare parts to stock varies greatly
depending on many factors such as the criticality of the
application, the time required to buy and receive new
spares, the erosive/corrosive nature of the application,
and the cost of the spare part. Section 8 identifies all of
the components that make up each pump addressed in
this manual.
Prior to resizing impellers in high
chrome iron and nickel, please consult your local
Flowserve sales representative.
6.2.1 Ordering of spare parts
Flowserve keeps records of all pumps that have been

6.6 Setting impeller clearance and
impeller replacement
A new impeller gasket [4590.2] must be installed
whenever the impeller has been removed from the
shaft. Impeller balancing instruction may be found in
section 6.8.
Do not adjust the impeller clearance with the seal set.
Doing so may result in seal leakage and/or damage.
The impeller could have sharp edges,
which could cause an injury. It is very important to
wear heavy gloves when handling the impeller.
It is recommended that two people
install a Group 3 impeller. The weight of a Group 3
impeller greatly increases the chance of thread
damage and subsequent lock-up concerns.
Do not attempt to tighten or loosen the
impeller on the shaft by hitting the impeller with a
hammer or any other object or by inserting a pry bar
between the impeller vanes. Serious damage to the
impeller may result from such actions.
Care should be taken in the handling
of high chrome iron impellers.
6.6.1 Impeller installation
The impeller is threaded to the shaft in a clockwise
direction (right hand threads). Apply a coat of grease
or anti-seize to the threads to allow for ease of
disassembly in the future. Install a new impeller
gasket [4590.2].
Using a strap wrench to hold the drive coupling,
screw impeller [2200] onto the end of the pump shaft
[2100] clockwise until snugly fit. A second strap
wrench may be utilized to fully tighten the impeller
and compress the impeller gasket [4590.2]. The
gasket must be fully compressed to ensure an
accurate and stable impeller setting.
If available, an impeller wrench may be utilized to
tighten the impeller. Using the shaft key [6700.2],
mount the impeller wrench to the end of the shaft.
The impeller wrench is placed on the shaft at the
coupling end with a key. With the impeller wrench in
place, grasp the impeller in both hands (wear heavy
gloves] and, with the impeller wrench handle to the
left (viewed from the impeller end of the shaft) spin
the impeller forcefully in a clockwise direction to
impact the impeller wrench handle on the work
surface to the right.
6.6.2 Impeller Removal
Remove the impeller [2200] by unscrewing it counterclockwise (looking in at the vanes).
Do not apply heat to the impeller. If liquid is
entrapped in the hub, an explosion could occur.
While holding the drive coupling with a strap wrench,
unscrew the impeller. Do not attempt to use a
crowbar as a lever to unscrew the impeller as
damage to the vanes may result. Use a strap wrench
or a piece of wood as a mallet. Discard the impeller
gasket [4590.2]
If available, an impeller wrench may be utilized to
loosen the impeller. Using the shaft key [6700.2],
mount the impeller wrench to the end of the shaft.
With the wrench handle pointing to the left when
viewed from the impeller end, grasp the impeller
[2200] firmly with both hands (wear heavy gloves).
By turning the impeller in the clockwise direction
move the wrench handle to the 11 o’clock position
and then spin the impeller quickly in a counterclockwise direction so that the wrench makes a
sudden impact with a hard surface on the bench.
After several sharp raps, the impeller should be free.
Unscrew the impeller and remove from the shaft.
Discard the impeller gasket [4590.2].
6.6.3 Impeller Setting
Several types of impellers are available for the ESP3
product. Reverse vane and Recessed impellers are
set off the rear cover. Open impellers and Lo-Flo
impellers are set off the casing. Impeller setting is
performed by adjusting the impeller to the correct
surface as described above and then adjusting it to
the correct gap. For services above 82 °C (180 °F)
add another two combinations of shaft keyway/sleeve
slots to the values listed.
6.6.3.1 Reverse vane and Recessed impeller
setting
a) Rotate the shaft [2100] so that the impeller
adjustment key [6700.3] is toward you.
b) Remove the retaining ring [2530.2] and key
[6700.3] from the adjusting sleeve [3400].
c) Holding the shaft [2100] steady, turn the
adjusting sleeve [3400] clockwise until the
impeller [2200] is resting against the running
face of the cover [1220].
Page 40
ESP3 USER INSTRUCTIONS ENGLISH 26999943 08-11
of 64
d) Back the impeller [2200] off the cover [1220] by
rotating the adjusting sleeve [3400]
counterclockwise so that the next slot lines up
with one of the shaft keyways:
e) For GP1 and 2 Pumps, continue to rotate the
sleeve [3400] in the same direction for an
additional four or five combinations of shaft
keyway/sleeve slots (22.5 degrees each - the
keyway that lines up will alternate as the sleeve
[3400] is turned).
For GP3 Pumps continue to rotate the sleeve
[3400] in the same direction for another five or
six combinations of shaft keyway/sleeve slots
(22.5 degrees each - the keyway that lines up
will alternate as the sleeve [3400] is turned)
f) Install the impeller adjustment key [6700.3) and
retaining ring [2530.2] back into position.
g) Check for freedom of shaft [2100] rotation by
turning by hand.
As the reverse vane and Recessed Impellers
are set from the read cover, these settings can be made
in the shop. If setting is being performed in the shop,
less casing, it is advisable to leave out the impeller
gasket [4590.2] during impeller setting. This will ensure
that the impeller is fully seated and will not tighten
further in operation. The impeller gasket must be
installed before the casing is installed.
6.6.3.2 Open and Lo-Flo impeller setting
a) Rotate the shaft [2100] so that the impeller
adjustment key [6700.3] is toward you.
b) Remove the retaining ring [2530.2] and key
[6700.3] from the adjusting sleeve [3400].
c) Holding the shaft [2100] steady, turn the
adjusting sleeve [3400] counterclockwise until
the impeller [2200] is resting against the running
face of the casing [1100].
d) Back the impeller [2200] off the casing [1100] by
rotating the adjusting sleeve [3400] clockwise so
that the next slot lines up with one of the shaft
keyways:
e) For GP1 and 2 Pumps, continue to rotate the
sleeve [3400] in the same direction for an
additional four or five combinations of shaft
keyway/sleeve slots (22.5 degrees each - the
keyway that lines up will alternate as the sleeve
[3400] is turned).
For GP3 Pumps continue to rotate the sleeve
[3400] in the same direction for another five or
six combinations of shaft keyway/sleeve slots
(22.5 degrees each - the keyway that lines up
will alternate as the sleeve [3400] is turned)
f) Install the impeller adjustment key [6700.3] and
retaining ring [2530.2] back into position.
g) Check for freedom of shaft [2100] rotation by
turning by hand.
6.7 Disassembly
Use extreme care in removing and dismantling pump.
Refer to pump assembly drawings for part
nomenclature (see Section 8).
Lock out power to driver to prevent personal
injury.
If Flowserve ESP3 pumps contain dangerous
chemicals, it is important to follow plant safety
guidelines to avoid personal injury or death.
6.7.1 Removing pump from pit
a) Close control valve in discharge line.
b) Lock out power supply to driver.
c) Disconnect all electrical connections.
d) Close all valves on auxiliary equipment and
piping then disconnect all auxiliary piping.
e) Disconnect discharge piping from pump.
f) Remove coupling guard [7450.1-.2] and coupling
halves [7200].
g) Disconnect driver [8000] and remove.
h) Unbolt pump mounting plate [6130] and lift pump
(see Sections 2.3 and 4.4) from pit. Let the
pump drain thoroughly before removing pump
completely. Remove casing drain [6515.1], if
supplied.
i) Remove liquid level controls (if any).
j) Lift the pump (see Sections 2.3 and 4.4) out of
the pit and lay pump horizontally on supports.
For units that are welded, the welded
sections should not be disassembled unless the parts
need to be replaced.
6.7.2 Pump disassembly
a) Pump discharge pipe removal
•Discharge pipes four inches and less:
Unscrew the flange [1245.2], locknut [3400], and
loosen the lower locknut. Then the upper
discharge pipe [1360] can be unscrewed.
Discharge pipes greater than four inches:
Unscrew the flange [1245.2]. These pumps are
furnished with the discharge pipe bolted to the
mounting plate [6130] by a flange [1245.3] and
four screws [6570.11]. Remove the screws
holding the flange to the mounting plate [6130].
•The discharge pipe [1360] can then be removed
by unbolting the elbow [1371] from the discharge
of the casing [1100) and pulling the discharge
pipe out from the underside of the mounting plate
[6130].

of 64
b) Remove bearing lubrication lines [3840.1].
c) Unbolt and remove the pump casing [1100].
The cove plate [1220] may only
be held in place by the casing and could fall
when the casing is removed.
If applicable, remove the two cap screws
[6570.16] which attach the rear cover [1220] to
the adapter. Carefully remove this part. The
strainer [6531] does not need to be removed
from the casing unless it is to be cleaned or
replaced.
d) Remove the impeller [2200] by unscrewing it
counterclockwise. See section 6.6.2 for
instructions.
Do not apply heat to the impeller. If liquid is
entrapped in the hub, an explosion could occur.
e) Remove the shaft sleeve [2400]
f) Remove the support head [3160].
Pumps without Vapor Proof or Pressurized
Construction
For groups 1 and 2 the support head will be
disconnected from the mounting plate [6130].
For group 3 the support head will be
disconnected from the upper column [1341.1].
For Group 3 pumps, any columns
still attached to the pump at this time must be
firmly supported. The upper column will
disconnect from the mounting plate at the same
time that the support head is disconnected.
Pumps with Vapor Proof or Pressurized
Construction:
remove the support head [3160] from the
bearing bracket [4310.2]
g) Remove coupling hub.
h) Pumps with Vapor Proof or Pressurized
Construction:
If a cartridge type mechanical seal [4200] is
used, the spacing clips or tabs should be
installed prior to loosening the setscrews which
attaches the seal to the shaft. This will ensure
that the proper seal compression is maintained.
It will also help prevent damage to the seal in
the following steps.
i) Unbolt and remove the bearing body [3110]
j) Remove the retaining ring [2530.2] and key
[6700.3] from the adjusting sleeve [3400].
k) Holding the shaft [2100] steady, turn the
adjusting sleeve [3400] counterclockwise to
remove the assembly from the shaft
l) Remove the bearing bracket [4310.2] for pump
with Vapor Proof or Pressurized Construction
only.
For groups 1 and 2 the bearing bracket will be
disconnected from the mounting plate [6130]
For group 3 the bearing bracket will be
disconnected from the upper column [1341.1].
For Group 3 pumps, any columns still
attached to the pump at this time must be firmly
supported. The upper column will disconnect from
the mounting plate at the same time that the bearing
bracket is disconnected.
Before the next procedure, be sure to
cover the shaft threads with a Teflon tape for
protection when sliding parts off the shaft to prevent
the shaft threads from being damaged or causing
damage to other parts.
m) Pumps with Vapor Proof or Pressurized
Construction only.
Unbolt the gland [4120.1 or 4120.3] and
carefully slide it off the end of the shaft. If the
pump contains a seal, VERY CAREFULLY, slide
the seal off of the shaft. Remove all seal
components and discard all O-rings and
gaskets. If the pump contains packing remove
the packing at this time.
n) Now the stuffing box [4110] can be unbolted and
removed gently from the shaft.
o) A shaft-nose cone (See Figure 6-3) is
recommended, but not required, for the next
step. If a shaft nose cone is to be used, attach
the cone in place of the impeller [2200]. Remove
the shaft [2100] from the remainder of the pump.
Always remove the shaft by pulling it
out through the mounting plate end as shaft threads
may cause damage to the line shaft bearings if pulled
through the casing end.
p) Unbolt and remove the adapter [1340.1].
q) Unbolt and remove the intermediate columns
[1341.2] and the bearing holders [3250] until the
upper column is reached [1341.1].
r) The shaft bearings should not be removed from
their housings unless they are to be replaced.
Figure 6.6 shows a listing of allowable bearing
tolerances. If these tolerances are exceeded,
either the bearings [3020.1-.2], shaft [2100], or
bearing holder [3250] should be replaced.
s) Intermediate shaft bearings [3020.1] can be
pressed or driven out of their bearing holder
[3250] when replacing.
t) The adapter bearing [3020.2] may be removed
by pressing or driving the bearing sleeve from
the upper flange (column side) out through the
lower end (casing side) of the adapter [1340.1].
u) Removal of bearings [3031] from adjusting
sleeve [3400]. Remove snap ring [2530.2]. An
arbor or hydraulic press may be used to remove
the bearings from the adjusting sleeve. It is
extremely important to apply even pressure to
the inner bearing race only. Never apply
pressure to the outer race as this exerts excess
load on the balls and causes damage.
Applying pressure to the outer
race could permanently damage the bearings.
x) If lip seals [4310.1] and [4310.2] (see figure 6-4)
are used, they should be removed and discarded.
Figure 6-4
6.8 Examination of parts
6.8.1 Cleaning/inspection
All parts should now be thoroughly cleaned and
inspected. New bearings, O-rings, gaskets, and lip
seals must be used. Any parts that show wear or
corrosion should be replaced with new genuine
Flowserve parts.
It is important that only non-flammable,
non-contaminated cleaning fluids are used. These
fluids must comply with plant safety and environmental
guidelines.
a) Inspect impeller [2200] for excessive wear and
etching due to corrosion. Large nicks and deep
pits will unbalance the impeller, cause vibration,
and wear in other parts of the pump. Be sure the
O-ring [4590.2] sealing surface and impeller
threads are clean.
b) Check pump shaft [2100] for straightness.
c) Inspect the surface of the shaft in the bearing
[3020.1-.2] areas to make sure it is smooth. It
must be free of grooves, scratches, corrosion or
wear.
d) Check ends of shaft for burrs. Make sure that
shaft threads are clean.
e) Inspect the casing [1100] thoroughly, removing
all burrs and foreign matter. Check hydraulic
passages for cleanliness.
f) Check all other parts for burrs, wear, damage or
corrosion.
g) Use a dial indicator to check the straightness of
adapter [1340.1] and intermediate bearing
holder(s) [3250]. Check for cracks, uneven or
excessive wear, scoring or heat discoloration,
and corrosion. Bearings should be replaced as
described in Section 6.7.2.
6.8.2 Critical measurements and tolerances
To maximize reliability of pumps, it is important that
certain parameters and dimensions are measured
and maintained within specified tolerances. It is
important that all parts be checked. Any parts that do
not conform to the specifications should be replaced
with new Flowserve parts.
6.8.3 Parameters that should be checked by
users
Flowserve recommends that the user check the
measurements and tolerances in Figure 6-6
whenever pump maintenance is performed. Each of
these measurements is described in more detail on
the following pages.
6.8.3.1 Shaft
Replace if grooved, pitted or worn, especially where
the shaft rides in the sleeve bearings.
6.8.3.2 Bearings
It is recommended that rolling element bearings not
be used after removal from the shaft.
6.8.3.3 Impeller balancing
To minimize shaft whip it is imperative that the
impeller is balanced. All impellers manufactured by
Flowserve are balanced after they are trimmed. If for
any reason, a customer trims an impeller, it must be
re-balanced.
The maximum values of acceptable unbalance are:
• Up to 1800 rpm: 40 g·mm/kg (0.021 oz-in/lb)
• Above1800 rpm: 20 g·mm/kg (0.011 oz-in/lb)
Flowserve performs a single plane spin balance on
most impellers. The following impellers are
exceptions: 10X8-14, 10X8-16 and 10x8-16H. On
these Flowserve performs a two plane dynamic
balance, as required by the ASME B73.1M standard.
All balancing, whether single or two plane, is
performed to the ISO 1940 Grade 6.3 tolerance
criteria.
6.8.3.4 Vibration analysis
Vibration analysis is a type of condition monitoring
where a pump’s vibration “signature” is monitored on
a regular, periodic basis. The primary goal of
vibration analysis is extension on MTBPM. By using
this tool Flowserve can often determine not only the
existence of a problem before it becomes serious, but
also the root cause and possible solution.
Modern vibration analysis equipment not only detects
if a vibration problem exists, but can also suggest the
cause of the problem. On a centrifugal pump, these
causes can include the following: unbalance,
misalignment, defective bearings, resonance,
hydraulic forces, cavitation and recirculation. Once
identified, the problem can be corrected, leading to
increased MTBPM for the pump.
Flowserve strongly urges customers to work with an
equipment supplier or consultant to establish an ongoing vibration analysis program.

6.9 Assembly of pump and seal
It is important that all pipe threads be
sealed properly. PTFE tape provides a very reliable
seal over a wide range of fluids, but it has a serious
shortcoming if not installed properly. If, during
application to the threads, the tape is wrapped over the
end of the male thread, strings of the tape will be
formed when threaded into the female fitting. These
strings can then tear away and lodge in the piping
system.
If this occurs in the seal flush system, small orifices can
become blocked effectively shutting off flow. For this
reason, Flowserve does not recommend the use of
PTFE tape as a thread sealant.
Flowserve has investigated and tested alternate
sealants and has identified two that provide an
effective seal, have the same chemical resistance as
the tape, and will not plug flush systems. These are
La-co Slic-Tite and Bakerseal. Both products contain
finely ground PTFE particles in an oil-based carrier.
They are supplied in a paste form which is brushed
onto the male pipe threads. Flowserve recommends
using one of these paste sealants.
Full thread length engagement is required for all
fasteners.

Figure 6-8.
b) After removing the adapter bearing [3020.2] (see
section 6.7.2) clean and deburr adapter bore and
lubrication port. Apply a light coating of grease or
oil to bearing holder bore and outside diameters
of new bearings. Carefully press the new bearing
into the adapter flush with the counter bore as shown
in Figure 6-9.
c) Be sure that all bearings [3020.1-.2] are now
within their bearing holders [3250, 1340.1].

6.9.2 Assembling mounting plate, column(s),
adapter and shaft
If a shaft nose cone is available, the mounting plate,
column(s), intermediate bearing(s) and adapter may
be assembled prior to shaft insertion. If a nose cone
is not available, the pump must be built in section
over the shaft. Use of a shaft nose cone is
recommended.
a) Standard and vapor tight construction:
connect the upper column [1341.1] to the
mounting plate [6130]. For Group 3, the upper
column and support head [3160] must be bolted
to the mounting plate at the same time.
In this configuration, the upper column
contains a lip seal [4310.2] which is installed with
the energizing spring down. Although installation
is more difficult, it is beneficial to install the lip seal
after shaft installation to prevent damage. Wrap
the shaft thread with Teflon tape to protect lip seal
from damage.
Vapor proof or pressurized construction:
replace the upper column gasket [4590.5] and
reconnect the upper column [1341.1] to the
mounting plate [6130]. For Group 3, the bearing
bracket [4310.2] must be bolted to the mounting
plate at the same time.
Assembly with nose cone
b) If intermediate bearings are used, install the
bearing holder [3250] and intermediate column
[1341.2] and bolt them together. Repeat for
each section.
c) Bolt the adapter [1340.1] back onto the last
column in the pump.
d) Screw the shaft bullet onto the end of the shaft
[2100] at the impeller end.
Always insert the shaft from the
mounting plate side of the pump. Never insert it from
the adapter side because shaft threads may cause
damage to the internal bearings.
e) The pump shaft [2100] should now be inserted
into the pump from the mounting plate side.
Standard and vapor tight construction require a
lip seal [4310.2] in the upper column. If the lip
seal is installed prior to the shaft, than ensure
the lip seal and shaft are lubricated to prevent
damage to the lip seal. The lip seal may be
installed after the shaft is slid into place, but
installation is more difficult (see section a) for
details). Fill the cavity between the lips ½ to
⅔full
Assembly without nose cone
It is important that the shaft and columns
are well supported after the shaft is partially inserted as
bending in the shaft may occur.
b) Insert the shaft from the motor side of the pump
through the starter column [1341.1] until the
shaft threads [for the thrust bearing - 3031] are
about 3 inches from the starter column
Standard and vapor tight construction require a
lip seal [4310.2] in the upper column. If the lip
seal is installed prior to the shaft, than ensure
the lip seal and shaft are lubricated to prevent
damage to the lip seal. The lip seal may be
installed at the end of this sequence, but
installation is more difficult (see section a) for
details).
c) If intermediate bearing(s) are used, slide the
bearing holder [3250] onto the end of the shaft
[2100], followed by the column [1341.2] and bolt
together. Repeat for each section.
d) Slide the adapter [1340.1] onto the shaft [2100]
and bolt to the column [1341.1] or [1341.2].
6.9.3 Cover, Impeller and Casing Installation
a) Install the cover [1220] to the adapter [1340.1].
If applicable, hold the cover in place with cap
screws [6570.16].
b) Install the impeller. Section 6.6 covers all
aspects of impeller installation. Install a new
gasket [4590.2], sleeve O-ring [4590.1] and
lubricate threads.
c) Place a new gasket [4590.1] on the gasket face
of the cover [1220] and bolt the casing [1100] to
the adapter [1340.1]
6.9.4 Ball bearing/Adjusting Sleeve Assembly
Mounting of bearings must be done in a clean
environment. Thrust bearing life can be drastically
reduced if even very small foreign particles work their
way into the bearings. Wear clean gloves.
Bearings should be removed from their protective
packaging only immediately before assembly to limit
exposure to possible contamination. After removing
Page 47
ESP3 USER INSTRUCTIONS ENGLISH 26999943 08-11
of 64
the packaging they should only come in contact with
clean hands, fixtures, tools and work surfaces.

Bearings have a slight interference fit
which requires that they be pressed on the adjuster with
an arbor or hydraulic press. Even force should be
applied to only the inner race. Never press on the outer
race, as the force will damage the balls and races.
An alternate method of installing bearings is to heat
the bearings to 93 °C (200 °F) by means of an oven
or induction heater. With this approach the bearing
must be quickly positioned on the adjuster.
Never heat the bearings above 110 °C (230 °F). To
do so will likely cause the bearing fits to permanently
change, leading to early failure.
Duplex angular contact bearings must be mounted
face-to-face with the wider thrust sides of the outer
races away from each other as shown in figure 6-10.
Only bearings designed for universal mounting
should be used. The SKF designation is “BEGAM”.
NTN’s designation is “BL1G”.
Figure 6-10
6.9.5 Seal and packing installation (if equipped)
Cover the shaft threads with a Teflon
tape to prevent them from causing internal damage to
other components.
a) Attach the stuffing box [4110] to the upper
column [1341.1]. NOTE: Some cartridge
(canister) seals are designed to bolt directly to
the upper column and will not have a separate
stuffing box.
b) Seal component installation
Component Seal that require setting:
Most component seals required setting. The
impeller must be set and the shaft marked at
box face before seal assembly can take place.
The following steps will build the pump to the
point the impeller can be set and the shaft
marked. The pump must then be disassembled
to the point that the seal can be installed and set
according to the instruction included with the
seal.
Figure 6-11 Typical Inside Component Seal
a) Press the bearings [3031) onto the adjusting
sleeve [3400) as shown in Figure 6-10. If the
bearings have been heated for installation, the
bearing should be pressed against the shoulder
after the bearing has cooled below 38 °C (100
°F).
b) Install snap ring [2530.2].
c) Pack the bearing with grease. See Figure 5-5.

Component Seals that do not require setting:
Most double component seals do not required
any settings. The seal may be installed at this
point according to the instructions provided with
the seal. Care must be taken that the seal rotor
is lubricated properly so that it will be able to
move on the shaft as the impeller is set in the
following steps.
Figure 6-13 Typical Double Component Seal
Cartridge and Gas Canister seal:
CAREFULLY slip the seal [4200] onto the shaft
[2100] and slide it down until it sets into the
stuffing box [4110] or upper column [1341.1] on
with Gas Canister type seals. DO NOT SET
THE SEAL AT THIS TIME. Leave the gland
nuts slightly loose.
Figure 6-14 Typical Cartridge Seal
Packing:
Install one ring at a time, pushing it well into
place. Two rings of packing must be installed,
the seal cage, then succeeding rings of packing
until the box is filled.
NOTE: The joints of succeeding rings must be
staggered. The taped hole in the stuffing box for
packing lubrication must line up with the seal
cage when the packing is compressed.
After the last ring of packing is in place, draw up
the nuts [6580.8] on the gland [4120.1] evenly
finger tight. Save additional packing rings as
they may become necessary as the packing is
tightened during operation.

The lower lip seal [4310.2] should be installed
with the spring down into the bearing bracket
[3130]. Fill the cavity between the lips ½ to ⅔
full with bearing grease. Install the bearing
bracket [3130] to the mounting plate [6130]
GP3 Pumps:
The bearing bracket [3130] has already been
installed. The lower lip seal [4310.2] should be
installed with the spring down into the bearing
adapter plate [1340.4]. Fill the cavity between
the lips ½ to ⅔ full with bearing grease. Install
the bearing adapter plate [1340.4] onto the top
of the bearing bracket [3130]. Temporarily hold
the adapter bracket in place with cap screws.
d) Install bearing/adjusting sleeve assembly.
Screw the adjusting sleeve [3400] to the shaft
e) Install O-ring [4590.2] and the bearing body
[3110]. Secure with cap screws [6570.9].

Component seals that do not required
setting:
Tighten the gland nuts [6580.8]
h) Components seals that required setting:
The following steps are only necessary for these
types of seals.
•Put bluing on the shaft and mark the shaft at
the face of the gland [4120.3]. This mark is
used as a reference for setting the seal.
• Remove the bearing body installed in step e).
• Remove the adjusting sleeve installed [3400]
in step d).
•Remove the bearing bracket [3130] or
adapter bracket installed in step c).
•Install and set the seal according the
instruction provided with the seal. Inside
component seal may prove difficult to set. If
necessary, remove the casing and impeller
so that the shaft may be moved to allow
access for setting the seal.
•Repeat steps c), d) and e).
Seals must never be run without
lubrication. Abrasive lubrication will greatly
reduce seal life.
A variety of seal piping plans designed to suit certain
pumping conditions and liquids are available.
6.9.6 Installation of ball bearings and housing
The following steps have previously been performed
for pumps with seals.
a) Install bearing/adjusting sleeve assembly.
Screw the adjusting sleeve [3400] to the shaft
b) Install O-ring [4610.2] and the bearing body
[3110]. Secure with cap screws [6570.9].
The bearing body contains lip seal [4310.1].
The lip seal is installed with the spring down.
Lubricate the lip seal with grease prior to placing
over the shaft. Fill the cavity between the lips ½
to ⅔full.
c) Set the impeller as described in section 6.6.3
6.9.7 Installation of motor support head
GP1 and 2 Pumps:
For pumps without seals, attach the support head
[3160] to the upper column [1341.1] with cap screws
[6579.2].
For pumps with seals, attach the support head [3160]
to the bearing bracket [4310.2] with cap screws
[6579.4]
GP3 Pumps:
For pumps without seals, the support head has
already been installed.
For pumps with seals, remove the cap screws
temporarily holding the bearing adapter plate [1340.4]
in place. Attach the support head to the adapter
bracket with cap screws.
6.9.8 Discharge piping
a) If the strainer [6531] had been removed for
cleaning or replacement purposes, reattach
strainer to suction flange of the casing.
b) Reconnect all bearing lubrication lines [3840.1].
c) For Groups 1, 2, and 6x4-13: At this point the
lower locknut [3400] should be screwed all the
way down the threads on the upper end of the
discharge pipe [1360]. The discharge elbow
[1371] should be screwed onto the lower end of
the discharge pipe (if not already). Check to see
if the companion flange [1245.1] is still
connected to the discharge elbow. Next, the
discharge pipe should be slid up through the
mounting plate [6130] until the companion flange
lines up with the discharge flange of the casing
[1100].
To ensure a proper seal at the casing
discharge flange, it is important that the companion
flange is connected to the casing before the upper
locknuts are tightened to against the mounting plate.
d) Replace the gasket [4590.2] between the
companion flange and the discharge flange of
the casing and bolt back together.
e) The upper locknut [6580.8] can now be screwed
onto the threads at the upper end of the
discharge pipe and both locknuts can be
tightened against the mounting plate.
f) For Group 3 (excluding 6x4x13): The
discharge pipe is attached the same way to the
casing discharge flange (see step “f” above).
The only difference in the assembly is that the
Group 3 pipes have a flange [1245.3] welded to
the discharge pipe [1360] that bolts to the
underside of the mounting plate [6130].
6.9.9 Final Assembly
•Ensure ball bearing, line shaft bearings, and seal
lubrication lines are installed
•Grease the thrust bearing [3031] with initial lube
quantity found in figure 5-5.
• Follow the installation instruction in section 4.
• Follow the instruction found in section 5.
• Ensure all guards are in place.

sump, lengthen pump or lower fluid temperature to increase the
NPSHa.
Reduce system head by increasing pipe size and/or reducing
number of fittings. Increase impeller diameter. (Note: Increasing
impeller diameter may require use of a larger motor.)
1. Check for air entrainment sources in the sump.
2. If vortex formation is observed in suction tank, install a vortex
breaker.
3. Check for minimum submergence.
After confirming wrong rotation, reverse any two of three leads on
a three phase motor. The pump should be disassembled and
inspected before it is restarted.
Replace with proper diameter impeller. (NOTE: Increasing
impeller diameter may require use of a larger motor.)
1. Reduce length of fiber when possible.
2. Reduce solids in the process fluid when possible.
3. Consider larger pump.
4. Clean strainer.
Replace part or parts.
If pump and bearing system has run dry for a long period,
disassemble and inspect the pump before operation.
1. Check and reset impeller clearance.
2. Check outboard bearing assembly for axial endplay.
2. Rapid temperature changes; increase impeller clearance.
Add sump vortex breakers to avoid adverse fluid rotation as it
approaches the impeller. Consult ANSI/HI 2.3.5
1. Work with clean tools in clean surroundings.
2. Remove all outside dirt from housing before exposing bearings.
3. Use clean solvent and flushing oil.
4. Protect disassembled bearing from dirt and moisture.
5. Clean inside of bearing body before replacing bearing.
6. Check lip seals and replace as required.
7. Check all plugs and tapped openings for tightness.
Adjust VFD or install proper speed motor.

PROBABLE CAUSES POSSIBLE REMEDIES
Too much flow.
Brinelling of bearing identified by
indentation on the ball races, usually
caused by incorrectly applied forces
in assembling the bearing or by shock
loading such as hitting the bearing or
drive shaft with a hammer.
False brinelling of bearing identified
indentations usually caused by
vibration of the balls between the
races in a stationary bearing.
Thrust overload on bearing identified
by flaking ball path on one side of the
outer race or in the case of maximum
capacity bearings, may appear as a
spalling of the races in the vicinity of
the loading slot. These thrust failures
are caused by improper mounting of
the bearing or excessive thrust loads.
Misalignment identified by fracture of
ball retainer or a wide ball path on the
inner race and a narrower cocked ball
path on the outer race. Misalignment
is caused by poor mounting practices
or defective drive shaft. For example,
bearing not square with the centerline
or possibly a bent shaft due to
improper handling.
Bearing damaged by electric arcing
identified as electro- etching of both
inner and outer ring as a pitting or
cratering. Electrical arcing is caused
by a static electrical charge
emanating from belt drives, electrical
leakage or short-circuiting.
Bearing damage due to improper
lubrication, identified by one or more
of the following:
1. Abnormal bearing temperature
rise.
2. A stiff cracked grease appearance.
3. A brown or bluish discoloration of
the bearing races.
Liquid has higher viscosity or specific
gravity than thought.
Binding in the pump or driver. 1. Clean column mating surfaces.
System resistance to flow is too low. Close discharge valve more.
Reduce impeller diameter.
When mounting the bearing on the drive shaft use a proper size
ring and apply the pressure against the inner ring only. Be sure
when mounting a bearing to apply the mounting pressure slowly
and evenly.
1. Correct the source of vibration.
2. In units that may be out of service for extended periods, the
drive shaft should be turned over periodically to relubricate all
bearing surfaces at intervals of one to three months.
Follow correct mounting procedures for bearings.
Handle parts carefully and follow recommended mounting
procedures. Check all parts for proper fit and alignment.
1. Where current shunting through the bearing cannot be
corrected, a shunt in the form of a slip ring assembly should be
incorporated.
2. Check all wiring, insulation and rotor windings to be sure that
they are sound and all connections are properly made.
3. Where pumps are belt driven, consider the elimination of static
charges by proper grounding or consider belt material that is less
generative.
1. Be sure the lubricant is clean.
2. Be sure proper amount of lubricant is used. In the case of
greased lubricated bearings, be sure that there is space adjacent
to the bearing into which it can rid itself of excessive lubricant,
otherwise the bearing may overheat and fail prematurely.
3. Be sure the proper grade of lubricant is used.
Analyze fluid being pumped and adjust it or pump driver.
2. Pump shaft bent and binding in sleeve bearings.
