section 1.6.4 also applies.
NEVER DO MAINTENANCE WORK
WHEN THE UNIT IS CONNECTED TO POWER
GUARDS MUST NOT BE REMOVED WHILE
THE PUMP IS OPERATIONAL
DRAIN THE PUMP AND ISOLATE PIPEWORK
BEFORE DISMANTLING THE PUMP
The appropriate safety precautions should be taken
where the pumped liquids are hazardous.
FLUORO-ELASTOMERS (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.
Personnel qualification and training
1.6.2
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.
Safety action
1.6.3
This is a summary of conditions and actions to
prevent injury to personnel and damage to the
environment and to equipment. For products
APPLYING HEAT TO REMOVE IMPELLER
There may be occasions when the impeller has either
been shrunk fit on to the pump shaft or has become
difficult to remove due to products of corrosion.
If you elect to use heat to remove the impeller, it must
be applied quickly to the impeller boss. TAKE GREAT CARE!
Before applying heat ensure any residual hazardous
liquid trapped between the impeller and pump shaft is
thoroughly drained out through the impeller keyway
to prevent an explosion or emission of toxic vapour.
This must be carried out with the shaft in the vertical
position. On some pump sizes a cavity exists in the
impeller bore so on occasions a significant volume of
liquid may drain out.
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.
HOT (and cold) PARTS
If hot or freezing components or auxiliary heating
supplies can present a danger to operators and
persons entering the immediate area action must be
Page 5 of 76 flowserve.com
VERTICAL TURBINE PUMPS (VTPS) CENTRIFUGAL PUMPS ENGLISH 71569224 – 10-13
taken to avoid accidental contact. 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
immediate area. Note: bearing housings must not be
insulated and drive motors and bearings may be hot.
If the temperature is greater than 80 ºC (175 ºF) or
below -5 ºC (23 ºF) 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 siting of the pump, 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.)
START THE PUMP WITH OUTLET
VALVE PARTLY OPENED
(Unless otherwise instructed at a specific point in the
User Instructions.)
This is recommended to minimize the risk of
overloading and damaging the pump motor at full or
zero flow. Pumps may be started with the valve
further open only on installations where this situation
cannot occur. The pump outlet control valve may
need to be adjusted to comply with the duty following
the run-up process. (See section 5, Commissioning start-up, operation and shutdown.)
NEVER RUN THE PUMP DRY
INLET VALVES TO BE FULLY OPEN
WHEN PUMP IS RUNNING
Running the pump at zero flow or below the
recommended minimum flow continuously will cause
damage to the pump and mechanical seal.
the motor and cause cavitations. Low flow rates may
cause a reduction in pump/bearing life, overheating of
the pump, instability and cavitation/vibration.
Products used in potentially explosive
1.6.4
atmospheres
Measures are required to:
Avoid excess temperature
Prevent build up 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.
For ATEX, both electrical and non-electrical
equipment must meet the requirements of European
Directive 94/9/EC. Always observe the regional legal
Ex requirements eg Ex electrical items outside the
EU may be required certified to other than ATEX eg
IECEx, UL.
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 ATEX pump set
shall select the coupling, driver 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 and so, for
pumps sets with a VFD, the ATEX Certification for the
motor must state that it is covers the situation where
electrical supply is from the VFD. This particular
requirement still applies even if the VFD is in a safe area.
DO NOT RUN THE PUMP AT
ABNORMALLY HIGH OR LOW FLOW RATES
Operating at a flow rate higher than normal or at a flow
rate with no back pressure on the pump may overload

ENSURE THE EQUIPMENT TEMPERATURE
CLASS IS SUITABLE FOR THE HAZARD ZONE
Pumps have a temperature class as stated in the
ATEX Ex rating on the nameplate. These are based
on a maximum ambient 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 that follows.

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 operator is responsible to ensure that the
specified maximum liquid temperature is not
exceeded
Temperature classification “Tx” is used when the
liquid temperature varies and the pump could be
installed in different hazarous 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.
If an explosive atmosphere exists during the
installation, do not attempt to check the direction of
rotation by starting the pump unfilled. Even a short
run time may give a high temperature resulting from
contact between rotating and stationary components.
Where there is any risk of the pump being run
against a closed valve generating high liquid and
casing 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 make routine vibration monitoring
checks.
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
mixture
ENSURE THE PUMP IS PROPERLY FILLED
AND VENTED AND DOES NOT RUN DRY
Ensure the pump and relevant suction and discharge
pipeline system is totally filled with liquid at all times
during the pump 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.
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.
Page 7 of 76 flowserve.com
VERTICAL TURBINE PUMPS (VTPS) CENTRIFUGAL PUMPS ENGLISH 71569224 – 10-13
Preventing sparks
1.6.4.5
To prevent a potential hazard from mechanical
contact, the coupling guard must be non-sparking.
To avoid the potential hazard from random induced
current generating a spark, the base plate must be
properly grounded.
Avoid electrostatic charge: do not rub non-metallic
surfaces with a dry cloth; ensure cloth is damp.
For ATEX applications the coupling must be selected
to comply with 94/9/EC. Correct coupling alignment
must be maintained.
Additional requirement for metallic pumps on
non-metallic base plates
When metallic components are fitted on a nonmetallic base plate they must be individually earthed.
1.6.4.6
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 ancillary 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
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
Preventing leakage
The pump must only be used to handle liquids

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.)

Instructions if required.
Noise Level
1.9
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.
Page 8 of 76 flowserve.com
VERTICAL TURBINE PUMPS (VTPS) CENTRIFUGAL PUMPS ENGLISH 71569224 – 10-13
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, pipework 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
motor” noise is that typically expected from standard
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 L
at 1 m
pA
(3.3 ft) from the machine, for “free field conditions
over a reflecting plane”.
For estimating sound power level L
(re 1pW) then
WA
add 17 dBA to the sound pressure value.
The noise levels shown in table 1.9.1 are
extracted from typical motor manufacturer’s
data/catalogue to provide the average expected
motor noise values at no load for reference only and
are not guaranteed. The values could vary
depending upon the test and surrounding conditions.
The combined noise level of the pump and the motor
could exceed the values shown. It is to be noted that
adding motors with similar noise levels increases the
total noise level. Therefore, the dB correction to the
values listed above is required to obtain the
combined noise levels of motor and the pump.
Actual on-site noise measurement by experts is
recommended and safety measures are to be taken
accordingly.

Drivers
3.3.1
A variety of drivers may be used, however, electric
motors are most common. For the purposes of this
manual, all types of drivers can be grouped into two
categories.
a) Hollow shaft drivers: where the head shaft extends
through a tube in the center of the rotor and is
connected to the driver by a clutch assembly at the top
of the driver.
b) Solid shaft drivers: where the rotor shaft is solid
and projects below the driver-mounting base. This
type driver requires an adjustable coupling for
connecting to the pump.
Discharge Head Assembly
3.3.2
(See also section 3.2.2.1)
The discharge head supports the driver and bowl
assembly as well as supplying a discharge connection
in most cases.

VERTICAL TURBINE PUMPS (VTPS) CENTRIFUGAL PUMPS ENGLISH 71569224 – 10-13
A shaft sealing arrangement is located in the
discharge head to seal the shaft at its exit from the
liquid chamber.
The shaft seal will usually be either a mechanical
seal assembly or stuffing box with an open lineshaft
or a tube-packing box with an enclosed lineshaft.
Column assembly
3.3.3
The column assembly consists of column pipe, which
connects the bowl assembly to the discharge head
and carries the pumped fluid to the discharge head.
Houses and supports the shaft and may contain
bearings. Typical column assemblies are:
a) flanged column assembly
See sectional drawings supplied with the pump for
exact column assembly details as per the order. The
size and configuration vary depending upon the
specific order requirements and application criteria.
3.3.4
Bowl assemblies
The bowl assembly consists of impellers rigidly
mounted on the pump shaft coupled to an electric
motor. Impellers are cast wheels with multiple diffuser
vanes and are generally coated to meet the hydraulic
requirements. See section 8.0 for cross sectional and
part details.
Suction strainers
3.3.5
VTPs can also be fitted with strainers [316] to prevent
foreign particles from entering the pump. The type of
strainers and the mesh size depends on the
application. Examples are shown below. Strainers
are fastened [422] directly to the suction bell [55] or
attached using clips [421]. Cone shaped strainers
are provided with internal or external threads to
attach it to the main assembly.

provision of correct foundation and installation may
lead to failure of the pump and, as such, would be
outside the terms of the warranty.
The foundation must consist of material that will afford
rigid support to the discharge head and will absorb
expected stresses that may be encountered in service.
Concrete foundations should have anchor bolts
installed in sleeves that allow alignment and have
holes in the mounting plate as illustrated in the detail
below. Sleeve should be filled with non-bonding
moldable material after sleeve is set in place.
When a suction barrel is supplied as in the case of the
type "TF" discharge head, the suction vessel must
provide permanent, rigid support for the pump and
motor.
All foundation / anchor bolt
recommendations should be verified by prevailing
industry standards.

Some wet pit pumps are installed directly by using
the flange that comes as an integral part of the
discharge head. The pump is lowered into the pit
and aligned with the anchor bolts [372].
The mounting flange is shimmed to achieve required
level by using a precision machinist’s level. The
pump is to be leveled to within 0.16 mm/m
(0.002 in./ft). The data to be recorded for future
reference. Anchor bolt nuts [373] are tightened
sufficient enough to hold down the pump in place.
Grout is poured and allowed to set for at least 72~80
hours (cure as required) before any further work is
done on the pump.
If leveling nuts are used to level the
base, they must be backed off as far as possible prior
to grouting.
Always shim near foundation bolts and then back off
the leveling nuts. Now tighten the foundation bolts. If
done otherwise there is a risk of significantly lowering
the structural natural frequency that could result in
separation of the base from the grout.
Directly mounted pumps are not user
friendly for service. Re-installation of these pumps
requires re-leveling and re-grouting.

Flowserve service center for advice.
Grouting provides solid contact between the pump
unit and foundation that prevents lateral movement of

See sections 4.2.1~4.2.4 for pump leveling details.
Position lifting equipment so it will center over the
foundation opening.
Installation of couplings on solid shaft
4.5.3
drivers.
If the pump purchased is having a solid
shaft driver, one of the following coupling
arrangement between the driver and the pump shaft
is applicable. Choose the procedure appropriate to
the coupling arrangement required.
Sump and piping should be
thoroughly cleaned of all loose debris before starting
installation.
Set up installation unit so that the lifting cable will be
centered directly over the well or sump. Carefully lift
the bowl assembly and suction barrel with a clamp.
Lower the bowl assembly into the well or sump. Set
the clamps or holding device that is attached to bowls
on a flat surface. This is to stabilize bowl assembly
and reduce possibility of cross threading the shaft.
a) When installing 152 mm (6 in.) or 203 mm (8 in.)
pump assembly, leave the pump securely
fastened to the wooden skid (as shipped) until the
bowl assembly is raised to a vertical position
b) Lift the pump to a vertical position. If a strainer is
used, attach it to the bowl assembly.
c) Position pump over sump or suction barrel. Align
the discharge of the pump with external piping
then lower onto the base. Level the entire pump.
d) If a stuffing box and a hollow shaft driver are
included, attach the head shaft to the pump shaft
(left hand threads).
e) If a mechanical seal is included, install the seal at
this point per the attached instructions.
If the pump includes a suction barrel (can), follow the
procedure as listed below. (See lifting instructions in
section 2.3)
a) Install the suction barrel first and grout the
mounting flange and bolts directly to the
foundation.
b) If soleplate is used, mount and grout the
soleplate and mount the suction barrel onto the
soleplate.
c) Level the soleplate & the suction barrel flange as
required.
d) Check to ensure suction barrel is free of debris
and other foreign material.
e) Install the pump.
Clean threads on pump shaft and on
adjusting nut.
Check for burrs and nicks.
All burrs, nicks and rust must be removed from all
mating parts of flanged coupling and pump before
installation. Failure to remove all burrs, nicks and
rust may result in misalignment causing pump to fail.
4.5.3.1
Installation of adjustable flanged

Installation of solid shaft driver without
jacking screws
When lowering the motor and driver
half of coupling onto pump, do not let pump half of
the coupling touch the driver half of the coupling.
Before bumping motor make sure coupling halves
are not touching and that the driver can rotate freely,
without rotating the pump
Driver half coupling must be in proper position so the
circular key will not come out.
a) Clean driver mounting flange on discharge head
and check for burrs or nicks on the register and
mounting face. Oil lightly.
b) Center motor over pump and rotate to align
mounting holes.
Electric motors: Rotate junction box into desired
position.
Gear Drives: Rotate input shaft into desired
position.
c) Lower driver carefully into place making certain
that the female register on the driver mates over
the male register on the pump.
d) Bolt driver to discharge head.
e) Check driver manufacturer's instructions for
special instructions including lubrication
instructions and follow all "startup" instructions.
f) Electric drivers should be checked for rotation at
this time. Make electrical connections "bump"
motor (momentarily start, then stop) to check
rotation. DRIVER MUST ROTATE
COUNTERCLOCKWISE when looking down at
top end of motor. To change the direction of
rotation on a three-phase motor, interchange any
two line leads. To change direction of rotation on
a two-phase motor, interchange the leads of either
phase.
g) See impeller adjustment instructions (section 5.3)
before bolting the pump and driver half of the

4.5.4.3
Installation of solid shaft driver with
jacking screws
a) Clean driver mounting flange on discharge head
and check for burrs or nicks on the register and
mounting face. Oil lightly.
b) Center motor over pump and rotate to align
mounting holes.
Electric motors: Rotate junction box into
desired position.
Gear Drives: Rotate input shaft into desired
position.
c) Lower driver carefully into place. Mount the dial
indicator base on the O.D. of the motor half
coupling. Set the indicator on the pump shaft,
position the dial to zero being careful that the
indicator is in direct line with one of the
jackscrews. Record this reading then rotate the
motor shaft and indicator 180 degrees. Record
this reading being careful to note plus or minus
values. Take the difference of the two readings
and using the jackscrews move the motor onehalf of the difference. Repeat this step until the
T.I.R. reading is a maximum of 0.051mm
(0.002in.). Then repeat this step for the set of
jack screws located 90 degrees to the first set.
Once all readings are within 0.051mm (0.002in.),
tighten motor bolts and check for any movement
in readings.
d) Check driver manufacturer's instructions for
special instructions including lubrication
instructions and follow all "startup" instructions.
e) Electric drivers should be checked for rotation at
this time. Make electrical connections and
"bump" motor (momentarily start, then stop) to
check rotation. DRIVER MUST ROTATE

two line leads. To change direction of rotation on
a two-phase motor, interchange the leads of
either phase.
f) See impeller adjustment instructions (section 5.3
before bolting the pump and driver half of the
coupling together.
Initial Alignment
4.6
4.6.1
Thermal expansion
The pump and motor will normally
have to be aligned at ambient temperature and
should be corrected to allow for thermal expansion at
operating temperature. In pump installations
involving high liquid temperatures greater than 300°F,
the unit should be run at the actual operating
temperature, shut down and the alignment checked
immediately.
Preparation before alignment
4.6.2
To ensure proper alignment the following items are
very important.
a) All machined mating surfaces (such as the
mating flanges of pump and motor) must be
clean and free of burrs and nicks.
b) Exterior strain must not be transmitted to the
pump. The most common cause of trouble is
forcing the piping to mate with the pump. It is
recommended that flexible connectors be installed
in the piping adjacent to the pump.
c) All threads should be checked for damage and
repaired if necessary. Lubricate all threaded
connections with a suitable thread lubricant (an
anti-galling compound).
Alignment methods
4.6.3
Ensure pump and driver are isolated
electrically and the half couplings are disconnected.
The alignment MUST be checked.
Although the pump will have been aligned at the
factory it is most likely that this alignment will have
been disturbed during transportation or handling.
If necessary, align the motor to the pump, not the
pump to the motor.
Adding or removing shims between the
motor and the discharge head helps alignment in the
vertical direction. The motor assembly may also
have to be adjusted in the horizontal direction to line
up the driver and shaft centers. Alignment screws
are provided to lock the motor assembly in its final
aligned position.
See section 5.3.2.1 for final coupling alignment for
solid shaft.
Before bumping motor make sure that the
coupling halves are not touching and that the driver
can rotate freely without rotating the pump. Driver
half coupling must be in proper position so the
circular key will not come out.
Angular and parallel misalignment
4.6.4
Check the direction of pump rotation
before the coupling is fully connected. The power
supply to the driver to be connected only after the
final alignment is complete.
a)
Angular of fset
Axial offset
b)
c)
Parallel offset
a) Angular Offset: The median lines of shaft
intersect halfway between the ends of the two
shafts.
b) Axial Offset: Another offset is the displacement
of one or both of the shafts. A typical example is
thermal expansion.
c) Parallel Offset: The median lines run parallel.
The maximum allowable parallel offset depends
on the size of coupling and is indicated in the
instruction manual of manufacturer of coupling.
For couplings with narrow flanges use a dial indicator
as shown in the detail to check both parallel and
angular alignment.

VERTICAL TURBINE PUMPS (VTPS) CENTRIFUGAL PUMPS ENGLISH 71569224 – 10-13
A
Par al l el
ngular
a) Pumps with thick flanged non-spacer couplings
can be aligned by using a straight-edge across
the outside diameters of the coupling hubs and
measuring the gap between the machined faces
using feeler gauges, measuring wedge or
calipers.
b) When the electric motor has sleeve bearings, it is
necessary to ensure that the motor is aligned to
run on its magnetic centerline.
Refer to the motor User Instructions for details.
If the motor does not run in its
magnetic center the resultant additional axial force
may overload the pump thrust bearing.
If the pump is handling hot liquid, the alignment must
be rechecked in warm condition of the unit. The
alignment of the unit shall be checked again after 200
service hours.
Pipe work velocities
4.7.1
In order to minimize friction losses and hydraulic
noise in the pipe work it is good practice to choose
pipe work that is one or two sizes larger than the
pump suction and discharge.
Typically, main pipe velocities should not exceed 2
m/s (6 ft/sec) on the suction and 3 m/s (9 ft/sec) on
discharge.
Take into account the available NPSH that must be
higher than the required NPSH of the pump.
Never use the pump as a support for
piping.
Maximum forces and moments allowed on
4.7.2
VTP pump flanges (See table 4.6.2.1)
Maximum forces and moments allowed on the pump
flanges vary with the pump size and type. To
minimize these forces and moments that may, if
excessive, cause misalignment, hot bearings, worn
couplings, vibration and possible failure of the pump
casing. The following points should be strictly
followed.
a) Prevent excessive external pipe load.
b) Never draw piping into place by applying force to
pump flange connections.
c) Do not mount expansion joints so that their force,
due to internal pressure, acts on the pump
flange.
Piping
4.7
Protective covers are fitted to the pipe
connections to prevent foreign particles or objects
entering the pump during transportation and
installation. Ensure that these covers are removed
from the pump before connecting pipes.
Page 31 of 76 flowserve.com
before use.
Ensure that the piping arrangement has been
provided to flush the pump before removal in cases
of hazardous liquid pumps.
Ensure piping and fittings are flushed

4.7.3.1
Normal pump leaks and gland leakage to be drained
through a separate piping arrangement or back into
the suction/sump.
4.7.3.2
The pumped liquid is allowed to flow through the
gland packing at discharge pressure and drained out
of the pump or re-circulated back into the suction. A
separate flush supply may be required in some
cases. The piping plans and flush supply are to be
selected based on the application and operating
parameters.
In some special cases where the discharge pressure
exceeds 6.5 bar (100 psi) a special flushing plan is
recommended.
4.7.3.3
Auxiliary piping to circulate the flushing liquid back
into the suction is required. In case of external clean
source requirements for pump applications such as
high temperature service, contaminated fluids,
oxidizing fluids, a special piping plan to carry the
clean liquid into the seal chamber with adequate
pressure is required and several piping plans are
available to suit the specific pump application.

Final Shaft Alignment Check
4.9
After connecting piping to the pump, rotate the shaft
several times by hand to ensure there is no binding
and all parts are free. Recheck the coupling
alignment, as previously described, to ensure no pipe
strain. If pipe strain exists, correct piping.
Protection Systems
4.10
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 the
bearings, it is recommended that temperature and/or
vibration monitoring is done on a regular basis.

5 COMMISSIONING, STARTUP,
OPERATION AND SHUTDOWN
These operations must be carried out
by fully qualified personnel. Turn off power supply for
safety while pump commissioning is in progress.
Pre-commissioning Procedure
5.1
The gland is to be filled with grease and flush supply
to be in place. Flush piping to be checked for leaks.
Mechanical seals to be checked for leaks, flush flow
and pressure.
a) Pumps with the enclosing tubes and oil-lubed
bearings must be filled with the proper lubricant to
avoid running dry and to guarantee acceptable
performance of the pump. A separate oil tank is
attached to the pump (see detail in section 5.2.2).
b) For can pumps check all vent connections for
complete filling of the pump. The venting
procedure can take from 10 minutes up to 2 hours,
depending on the kind of fluid .
c) Check the direction of rotation of the pump
(Coupling spacer dismantled). Should be counter
clockwise when viewed from the driver end.
d) The pump rotor and the shaft seal must be in
correct axial position.
e) Check the readiness of all auxiliary systems (seal
sys., lubrication system etc.,) for startup.
f) All pipe work, including the internal and the
auxiliary pipe work, must be connected correctly
and must be absolutely tight. Check the tightness
of all connections of the auxiliary pipe work. The
suction valve must be open, the discharge valve
shall be closed or partially open as required.
g) Turn the pump by hand, if required with the help of
a lever, to check the free rotation of the rotor. The
rotor must turn uniformly and noiselessly. Some
resistance may be felt due to the friction in the
bearings and seals.
h) Check the readiness of the driver for startup. Refer
to the manual for the driver to be sure that all
precautions are in place to energize the motor.
Pump Lubricants
5.2
Other than the stuffing box lubrication, mechanical
seal and/or lineshaft lubrication, the pump will not
require further periodic lubrication. On water pumps,
the suction bearing on the bowl assembly should be
repacked when required. Pumps that pump
hydrocarbons or have carbon, rubber, epoxy or
Teflon suction bearings do not have the suction
bearings packed. If the pump will be started after a
longer storage period, the bearings should be first
flushed and cleaned by using a suitable cleaning
agent. It is not necessary to remove the oil sprayed
for short or long-term storage as this will mix up
thoroughly with the lubrication oil.
Re-checking the motor lubrication should
be in accordance with the motor manufacturer’s user
instructions supplied separately with the pump.
Open lineshaft lubrication
5.2.1
Open lineshaft bearings are lubricated by the pumped
fluid where the static water level is less than 9 m (30 ft)
below the discharge head and will usually not require
pre or post-lubrication. Care is to be taken to ensure
that the gland or seal is supplied with the required
flush flow.
All open lineshaft pumps where the static water level is
more than 9 m (30 ft) below the discharge head should
be adequately pre-lubricated before starting the pump.
5.2.1.1
Allow flush water to flow down the shaft for 45
minutes for pumps over 9 m (30 ft) and increase the
pre-lube duration by at least 15 minutes for every 5 m
(15 ft) additional shaft length beyond 20 m (65 ft).
The fittings for pre-lube are provided at the discharge
head.
5.2.1.2
In general all W type cast discharge heads are
provided with a standard size pipe fitting for pre-lube
connection. Fabricated discharge heads are fitted
with a special piping arrangement to allow pre-lube
liquid flow onto the shaft.
Pre-lubrication duration
Typical pre-lube pipe connection
(examples (a) thru (d))
It is the responsibility of the user to install a
reliable pre-lube system to achieve the pump prelubrication. Flowserve will not supply these types of
systems or accessories with the pump.

Enclosed shaft lubrication
5.2.2
VTPs with the enclosed shafting are lubricated by a
dedicated oil supply system or injection lubricated by
extraneous liquid; usually clean water to meet the
application requirements.
5.2.2.1
Oil lubricated pumps
The lubricating oil must be available and should be
allowed to run into the enclosing tube in sufficient
quantity to thoroughly lubricate all lineshaft bearings.
The gravity flow system is the most commonly
utilized system for oil.
The oil reservoir (example shown in detail below)
must be kept filled with a good quality light turbine oil
(about 30 cSt) at the operating temperature and
adjusted to feed a minimum of 3 drops per minute
per 30 m (100 ft) of column length, at never less than
5 drops per minute total.

5.2.2.2
Pre-lubrication of oil lubricated pumps
As a general rule, the oil must be allowed to flow by
gravity at least 45 minutes before the pump is started
for the first time or in case the pump was turned off
for a longer duration. Adequate care should be taken
to make sure that the flow is available and is
consistent for subsequent startups.
5.2.2.3
Injection lubricated pumps
Enclosed lineshaft bearings are lubricated by
extraneous liquid (usually clean water), which is fed
to the tension nut either by gravity flow, or by a
pressure injection system.
The injected lubricant flow is never stopped for short
‘off ’ periods. Adequate care should be taken to
make sure that the flow is available and consistent
for subsequent startups and operation. Injection
pressure to be adjusted as recommended before the
startup.
Enclosed shaft lubricants
5.2.3
The following oils are recommended for enclosed
lineshaft bearing lubrication under normal operating
conditions. See tables 5.2.3.1 and 5.2.3.2.
It is recommended that detergent type
oils not be used.
5.2.3.1
Non-food/food grade lubricant oils
Equivalent turbine oil (food or non-food grades as
required) with the matching properties has to be
selected. Oils with a viscosity range of 30 cSt
2
(mm
/sec) to 37 cSt (mm2/sec) at 40 C (100 F) with a
minimum viscosity index of 90 are recommended.
The pour point of the oil must be in accordance with
the lowest expected temperature of the bearing
housing during a stop of the pump.
Oil level
5.2.4
The correct oil level is in the middle of the oil sight
glass and shall be checked when the pump is not in
operation. Periodically check if the lubricating oil is
mixed with any condensed water. Careful opening of
the oil drain during a stop of the pump will show any
water.
After the initial start the level will decrease
due to circulation of the oil through the bearings.
If the oil level is higher than specified, it could
result in higher bearing temperatures resulting in
poor lubrication.
Impeller Adjustment
Injection systems are designed for each
installation. Injection pressure and quantity of liquid
will vary. Normally 0.45-0.90 m
3
/h (2-4 gpm) at 0.7-
1.4 bar (10-20 psi) over maximum pump discharge
pressure of clean liquid is required.
5.2.2.4
Pre-lubrication of injection lubricated
pumps
As a general rule, the liquid flow is to be started at
least 15~20 minutes before the pump is started for
the first time or in the event of pump not being in use
for longer duration.
5.3
Proper impeller adjustment positions the impeller
inside the bowl assembly for maximum performance.
The impellers must be raised slightly to prevent them
from dragging on the bowls, but not raised too high so
as to adversely affect hydraulic performance.
The impeller must be down against the bowl seat
when starting impeller adjustment. When pumps are
subjected to suction pressure, the pressure acting
against the shaft tends to raise it. Make sure the shaft
is down when starting to adjust the impellers.
Page 38 of 76 flowserve.com
VERTICAL TURBINE PUMPS (VTPS) CENTRIFUGAL PUMPS ENGLISH 71569224 – 10-13
If, after making the impeller adjustment the pump does
not deliver its rated capacity, the impellers can be
lowered one step at a time until the lowest possible
adjustment is achieved without the impellers dragging.
On the other hand, if the impellers appear to be
dragging after the initial adjustment, the unit should be
stopped and the impellers raised one step. Dragging
impellers will increase the load significantly and can
usually be heard and felt as increased vibration. A
sharp rise in motor amperage will occur when
impellers are dragging.
Impeller adjustment for a hollow shaft
5.3.1
driver
Impeller adjustment when using hollow shaft drivers is
as follows. The driver canopy will have to be removed
before beginning.
a) Install headshaft [10] if not already in place.
b) Install driver clutch in accordance with the driver
instruction manual and bolt into place.
c) Check shaft position. Lower shaft until there is a
definite feel of metal contacting metal. This
indicates the impellers are "on bottom" and in the
correct starting position for impeller adjustment.
d) Thread headshaft nut [66] down (right hand
threads) except 43 mm (1.7 in.) and larger sizes
that are having left hand threads, until impellers
are just raised off their seat and the shaft will
rotate freely.
e) Check a separate document that is supplied with
the pump that provides recommended impeller
setting and running clearance information..

Note and record the T.I.R. reading. If this reading
is more than 0.25 mm (0.010 in.) for WA and WSA
couplings or 0.15 mm (0.006 in.) for PA and PSA
couplings, unbolt the drive and reposition the
driver in the direction required to reduce the T.I.R.
to within the allowable limits.
If a register fit is used for alignment,
driver will be able to be moved only a few
thousandths of an inch. If enough movement is
not obtainable then the male register can be filed
to obtain acceptable T.I.R. readings (Go to step
g).
f) On pumps using jackscrews for motor alignment,
mount the dial indicator base on the O.D. of the
motor half coupling. Set the indicator on the shaft,
position the dial to zero being careful that the
indicator is in direct line with one of the
jackscrews. Record this reading then rotate the
motor shaft and indicator 180 degrees.
Record this reading being careful to note plus or
minus values. Take the difference of the two
readings and using the jackscrews move the
motor one half of the difference. Repeat this step
until the T.I.R. reading is a maximum of 0.05 mm
(0.002 in.).
Page 40 of 76 flowserve.com
VERTICAL TURBINE PUMPS (VTPS) CENTRIFUGAL PUMPS ENGLISH 71569224 – 10-13
Then repeat this step for the set of jackscrews
located 90 degrees to the first set. Once all
readings are within 0.05 mm (0.002 in.) tighten
motor bolts and check for any movement in
readings.
g) Set the impeller setting gap between the
adjusting nut and the driver portion of the
coupling. See impeller setting data supplied
along with the pump. If this information is not
found, contact Flowserve. Align the match marks
on the pump half coupling with the driver half
coupling. On pumps with enclosed impellers the
match marks can be lined up by increasing the
impeller gap until the marks are in line with the
driver half coupling marks.
On pumps with semi-open impellers,
the match marks probably will not be in line when
the gap is set. DO NOT try to align the marking
on the nut with the other markings.
For pumps with enclosed impellers go to step (h).
h) Using 2 bolts of the coupling, at 180 degrees to
each other, slowly raise pump half coupling until
impellers are just lifted off the seat (This can be
gauged by trying to turn shaft by hand. At the
point the impellers are lifted the pump will turn).
Be sure to lift both sides evenly.
i) Measure the resultant gap between the motor half
coupling and the adjusting nut.
j) Find the difference between the original gap and
the new gap. Add this difference to the original
gap and reset the adjusting nut.
k) Bolt the coupling together and tighten bolts by
tightening opposite sides.
l) Remove wooden wedges, if used. Mount
magnetic base on pump and set the tip of indicator
on the shaft just above the seal. Slowly rotate the
shaft and note the T.I.R. reading.
Unless otherwise specified, the allowable T.I.R.
readings are:
WA and WSA couplings 0.10 mm (0.004 in.)
PA and PSA couplings 0.05 mm (0.002 in.)
If the reading is larger than the allowable values
specified above, unbolt the pump and rotate the driver
portion of the coupling to different hole and repeat
steps (h) and (i) until acceptable readings are
obtained.
m) If a mechanical seal is used, adjust the
mechanical seal at this time.
Direction of Rotation
5.4
Ensure the pump is given the same
rotation as specified or as marked on the
pump/driver. Please contact Flowserve
representative, if you have any questions before the
startup.
To avoid dry running the pump must either be filled
with liquid or have the flexible coupling disconnected
before the driver is switched on.
If maintenance work has been carried
out to the site's electricity supply, the direction of
rotation should be re-checked as above in case the
supply phasing has been altered.
Guarding
5.5
Guarding is supplied fitted to the pump set.
Fasteners for guards must remain captive in the guard
to comply with the Machinery Directive 2006/42/EC.
When releasing guards, the fasteners must be
unscrewed in an appropriate way to ensure that the
fasteners remain captive. Whenever guarding is
removed or disturbed ensure that all the protective
guards are securely refitted prior to start-up
Priming and Auxiliary Supplies
5.6
Ensure electrical, hydraulic,
pneumatic, sealant and lubrication systems (as
applicable) are connected and operational.
Ensure the inlet pipe and pump
casing are completely full of liquid before starting
continuous duty operation.

Location of the first stage impeller eye to be taken
into account for minimum priming submergence. It is
also equally important to take note of the minimum
distance to be maintained to the suction bell from the
sump floor (with or without strainer). Therefore, refer
to the Flowserve supplied general assembly drawing
on minimum submergence or contact Flowserve
before the pump is started.
Starting the Pump
5.7
Pre-starting checks
5.7.1
Before starting the pump the following checks should
be made.
a) Rotate the pump shaft by hand to make sure the
pump rotates freely and the impellers are
correctly positioned.
b) Ensure that the electric motor has been properly
lubricated in accordance with the instructions
furnished with the driver.
c) Ensure the electric motor has been checked for
proper rotation. The pump must be disconnected
from the driver at the coupling before checking.
The electric motor must rotate counter-clockwise
when looking down on the top of the driver.
d) Check all connections to the driver and control.
Do not overfill the grease cavity. Over greasing
can lead to overheating and premature failure of
the thrust bearing.
e) Check that all piping connections are tight.
f) Check all foundation bolts for tightness.
g) Check all bolting connections for tightness
(coupling bolts, mechanical seal gland bolts,
driver bolts etc).
h) Make sure the mechanical seal is properly
adjusted and locked into place. Ensure that all
seal spacers are in the running position prior to
operation.
i) All guards must be secured in position prior to
pump startup to prevent possible contact with
rotating parts.
To ensure proper alignment three items are very
important during installation and they are:
All machined mating surfaces (such as the
mating faces of the pump and motor) must be
clean and free from burrs and nicks.
These surfaces should be cleaned thoroughly
with a scraper, wire brush and emery cloth if
necessary and all nicks or burrs removed with a
fine file
Exterior strain must not be transmitted to the
pump. The most common cause of trouble in this
respect is forcing the piping to mate with the
pump. It is recommended that flexible
connectors be installed in the piping adjacent to
the pump.
All threads should be checked for damage and
repaired if necessary. If filing is necessary,
remove the part from the pump if possible, or
arrange to catch all the filings so they do not fall
onto other parts of the pump. Clean all threads
with a wire brush and approved cleaning solvent,
ends of shafts must be cleaned and any burrs
removed since alignment depends on the shaft
ends butting squarely. Lubricate all threaded
connections with a suitable approved thread
lubricant (an approved anti-galling compound
should be used on stainless mating threads)
j) On pumps equipped with mechanical seals, clean
fluid should be put into the seal chamber. With
pumps under suction pressure, this can be
accomplished by bleeding all air and vapor out of
the seal chamber and allowing the fluid to enter.
With pumps not under suction pressure, the seal
chamber should be flushed liberally with clean
fluid to provide initial lubrication. Make sure the
mechanical seal is properly adjusted and locked
into place. Insure that all seal spacers are
removed prior to operation.

INSTALLED
After initial startup, pre-lubrication of
the mechanical seal will usually not be required as
enough liquid will remain in the seal chamber for
subsequentstartup lubrication.
A screen guard is furnished with all pumps
having a two-piece headshaft or an adjustable
flanged coupling. This screen must be secured in
place prior to pump startup to prevent possible
contact with rotating parts. Typical arrangement is
shown in section 5.7.1.1.
Stuffing box adjustment
5.7.2
On the initial starting it is very important that the
packing not be tightened excessively. New packing
must be run in properly to prevent damage to the shaft
and shortening of the packing life.
The stuffing box must be allowed to leak for proper
operation. The proper amount of leakage can be
determined by checking the temperature of the
leakage, this should be cool or just lukewarm - NOT
HOT - usually 40 to 60 drops per minute will be
adequate.
When adjusting the packing gland, bring both nuts
down evenly and in small steps until the leakage is
reduced as required. The nuts should only be
tightened about one half turn at a time at 20 to 30
minute intervals to allow the packing to "run-in".
Under proper operation, a packing set will last a long
time. Occasionally a new ring of packing will need to
be added to keep the box full.
After adding two or three rings of packing, or when
proper adjustment cannot be achieved, the stuffing
box should be cleaned completely of all old packing
and re-packed.
Open shaft lubrication before startup
5.7.3
Open lineshaft bearings are lubricated by the
pumped fluid on short-coupled units less than 15 m
(50 ft) long and usually do not require pre- or postlubrication. All open lineshaft pumps where the static
water level is more than 15 m (50 ft) below the
discharge head should be adequately pre-lubricated
before startup. These units should have a nonreverse ratchet on the driver to prevent backspin
when turning off pump. If there is no NRR, postlubrication is also necessary.
Enclosed shaft lubrication before start up
5.7.4
Enclosed lineshaft bearings are lubricated by an
extraneous liquid (usually oil or clean water
The oil reservoir must be kept filled with a good
quality of light turbine oil (about 30 cSt (mm
2
/sec) at
operating temperature) and adjusted to feed 3
drops/minute for every 30 m (100 ft) of column.
Injection systems are designed for each installation.
Injection pressure and quantity of lubricating liquid
will vary. Usually 0.45 to 0.90 m
3
/h (2 to 4 gpm) at
0.7 to 0.14 bar (10 to 20 psi) over maximum pump
discharge pressure of clean liquid is required.
For recommended oils for enclosed lineshaft bearing
lubrication under normal operating conditions, please
see tables 5.2.3.1 and 5.2.3.2. If none of the above
oils are available, oil with the following specifications
should be obtained. Turbine type oil with rust and
oxidation inhibitors added, viscosity 30 cSt (mm
to 37 cSt (mm
2
/sec) at 40 C (100 F) with a minimum
2
/sec)
viscosity index of 90.
In the case of product-lubricated
bearings, the source of product supply should be
checked against the order. There may be
requirements for an external clean supply, particular
supply pressure or the commencement of lubrication
supply before pump startup.

Initial Starting
5.7.5
Ensure flushing and/or cooling/
heating liquid supplies are turned ON before
starting the pump.
a) If the discharge line has a valve in it, partially
open the discharge valve closest to the pump.
The discharge valve is intended to add sufficient
system resistance to the pump. Failure to
maintain pump flow rates within the limits of the
pump and motor could result in severe damage.
b) OPEN all inlet valves.
c) Prime the pump & check lubrication system in
operation (check the liquid level).
d) Ensure all vent connections are closed
before starting.
e) Check the motor connections.
f) Start pre-lubrication liquid flow on pump if
required.
g) Start the pump and observe the operation. If
there is any difficulty, excess noise or vibration,
stop the pump immediately and refer to the
Trouble Shooting Chart (section 7.0) to
determine the probable cause.
Do not run the pump with the outlet
valve closed for a period longer than 30 seconds.
h) Open vent connections and ensure that the unit
is vented of all trapped vapor before closing the
vents.
Observe extreme
caution when venting and or draining hazardous
liquids. Wear protective clothing in the presence of
caustic, corrosive, volatile, flammable or hot liquids.
Do not breathe toxic vapors. Do not allow sparking,
flames or hot surfaces in the vicinity of the equipment.
i) Open the discharge valve as desired to operate
the unit at its design conditions.
j) Check complete pump and driver for leaks, loose
connections, or improper operation.
If possible, the pump should be left running for
approximately one half hour on the initial startup, this
will allow the bearings, packing or seals, and other
parts to "run-in" and reduce the possibility of trouble
on future starts.
If abrasives or debris are present,
upon startup, the pump should be allowed to run until
the pumpage is clean. Stopping the pump when
handling large amounts of abrasives (as is
sometimes present on initial starting) may lock the
pump and cause more damage than the pump is
allowed to continue operation.
Every effort should be made to keep abrasives out of
lines, sump, etc. so that abrasives will not enter the
pump.
In the case of product lubricated
bearings the source of product supply should be
checked against the order. There may be
requirements for an external clean supply, particular
supply pressure or the commencement of lubrication
supply before pump start-up.
Frequency of lubrication
5.7.6
The characteristics of the installation and severity of
service will determine the frequency of lubrication.
Lubricant and pump/motor bearing temperature
analysis is useful in optimizing lubricant change
intervals.
The motor bearing temperature limitations should be
considered for its lubrication requirements. Refer to
the driver manufacturer’s user instructions supplied
with the pump. If documents are not found contact
Flowserve.
Never mix greases containing different
bases, thickeners or additives.
Normal vibration levels, alarm and trip
5.7.7
Pumps generally fall under classification of rigid
support machines within the International Rotating
Machinery standard and maximum vibration levels
are based on those standards
Alarm and trip values for installed
pumps should be based on the actual measurements
(N) taken on the pump in a fully commissioned (new)
condition. Measuring vibration at regular intervals
and recording will help to track any deterioration in
pump or operating conditions. Measurements shall
be taken at the pump/motor interface.

Motor start/stop frequency
Even though motors are normally suitable for at least
two consecutive starts, it is recommended to restart
only after coasting to rest between starts (minimum
of 15 minutes gap), with the motor initially at ambient
temperature. If more frequent starting is necessary,
refer to driver manufacturer’s instructions or contact
Flowserve with details.
The number of motor start and stops
in any given time affects motor life.
If the motor is expected to experience multi
starts in any given time, please refer to the driver’s
user instructions before the pump is put into
operation.
Operating the Pump
5.8
5.8.1
Venting the pump
Make sure that the pump is vented to enable
all trapped air to escape, taking due care with the
hazardous or hot liquids. Under normal conditions
after the pump is fully vented and primed, it should
be unnecessary to re-vent the pump.
DISCHARGE VENT LINE
SUCTION VENT LINE
SUCTION
SOURCE
SEALING LIQUID
Pumps fitted with packed glands
5.8.2
If the pump has a packed gland, there must be some
leakage from the gland. Gland nuts should initially
be finger-tight only. Leakage should take place soon
after the stuffing box is pressurized.
The gland must be adjusted evenly to give
visible leakage and concentric alignment of the gland
ring to avoid excess temperature. If no leakage
takes place, the packing will begin to overheat.
If overheating takes place, the pump should be
stopped and allowed to cool before being re-started.
When the pump is re-started, check to ensure
leakage is taking place at the packing gland.
If hot liquids are being pumped it may be necessary
to loosen the gland nuts to achieve leakage.
The pump should be run for 30 minutes with steady
leakage and the gland nuts tightened by 10 degrees
at a time until leakage is reduced to an acceptable
level, normally a minimum of 40-60 drops per minute
is required.
Care must be taken when adjusting the gland
on an operating pump. Safety gloves are essential.
Loose clothing must not be worn to avoid being
caught by the pump shaft. Shaft guards must be
replaced after the gland adjustment is complete.
Never run gland packing dry, even for
a short time.
Pumps fitted with mechanical seal
5.8.3
Mechanical seals require no adjustment. Any slight
initial leakage will stop when the seal is run in.
Before pumping dirty liquids, it is advisable, if
possible, to run in the pump mechanical seal using
clean liquid to safeguard the seal face.
External flush or quench should be
started before the pump is run and allowed to flow for
a period after the pump has stopped.
Never run a mechanical seal dry,
even for a short time.

VERTICAL TURBINE PUMPS (VTPS) CENTRIFUGAL PUMPS ENGLISH 71569224 – 10-13
Pump and motor bearing temperature
5.8.4
If the pumps are working in a potentially
explosive atmosphere, temperature or vibration
monitoring at the bearings is recommended.
If pump bearing temperatures (such as thrust
bearings) are to be monitored it is essential that a
benchmark temperature is recorded at the
commissioning stage and after the bearing
temperature has stabilized.
Record the bearing temperature (t) and the
ambient temperature (ta)
Estimate the likely maximum ambient
temperature (tb)
Set the alarm at (t+tb-ta+5) C [(t+tb-ta+10) F]
and the trip at 100 C (212 F) for oil lubrication
and 105 C (220 F) for grease lubrication
It is important, particularly with grease lubrication, to
keep a close watch on the bearing temperatures.
After startup the temperature rise should be gradual,
reaching a maximum after approximately 1.5 to 2
hours. This temperature rise should then remain
constant or marginally reduce with time.
5.8.5
Multiple Can Pump Operation
Additional procedures may be required in multiple
can pump systems when one or more pump remains
idle. Contact Flowserve for details.
Stopping and Shutdown
5.9
a) Close the outlet valve, but ensure that the pump
runs in this condition for no more than a few
seconds.
b) Stop the pump.
c) Switch off flushing and/or cooling/heating liquid
supplies at a time appropriate to the process.
For prolonged shutdowns and
especially when ambient temperatures are likely to
drop below freezing point, the pump and any cooling
and flushing arrangements must be drained or
otherwise protected.
Hydraulic, mechanical and electrical
5.10
duty
This product has been supplied to meet the
performance specifications of your purchase order,
however it is understood that during the life of the
product these may change. The following notes may
help the user decide how to evaluate the implications
of any change. If in doubt contact your nearest
Flowserve office.
5.10.1 Specific gravity (SG)
Pump capacity and total head in metres (feet) 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.
5.10.2 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 increased viscosity, and
reduces with reduced viscosity. It is important that
checks are made with your nearest Flowserve office
if changes in viscosity are planned.
5.10.3 Pump speed
Changing pump speed effects flow, total head, power
absorbed, NPSH
, noise and vibration. Flow varies in
R
direct proportion to pump speed, head varies as speed
ratio squared and power varies as speed ratio cubed.
The new duty, however, will also be dependent on the
system curve. If increasing the speed, it is important
therefore to ensure the maximum pump working
pressure is not exceeded, the driver is not overloaded,
NPSH
> NPSHR, and that noise and vibration are
A
within local requirements and regulations.

available in the pumped liquid, above its vapour
pressure, at the pump suction branch.
NPSH required (NPSH

performance curve to determine exact requirements
particularly if flow has changed.
If in doubt please consult your nearest Flowserve
office for advice and details of the minimum allowable
margin for your application.
5.10.5 Pumped flow
Flow must not fall outside the minimum and
maximum continuous safe flow shown on the pump
performance curve and or data sheet.

6 MAINTENANCE
General
6.1
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.
Guard fasteners must remain captive during
dismantling of guards as described in section 5.5
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 guard rails 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 an uncontrolled start. Put a warning board
on the starting device with the words:
"Machine under repair: do not start".
With electric drive equipment, lock the main switch
open and withdraw any fuses. Put a warning board
on the fuse box or main switch with the words:
"Machine under repair: do not connect".
Never clean equipment with inflammable solvents or
carbon tetrachloride. Protect yourself against toxic
fumes when using cleaning agents.
Maintenance Schedule
6.2
It is recommended that a maintenance plan
and schedule is adopted, in line 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 packings 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 if the hours
run show 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.
h) Check coupling alignment and re-align if
necessary.
Our specialist service personnel can help with
preventative maintenance records and provide
condition monitoring for temperature and vibration to
identify the onset of potential problems.
If any problems are found the following sequence of
actions should take place:
a) Refer to section 8, Faults; causes and remedies,
for fault diagnosis.
b) Ensure equipment complies with the
recommendations in this manual.

Routine inspection (daily/weekly)
6.2.1
The following checks should be
made and the appropriate action taken to remedy
any deviations.
a) Check operating behavior; ensure noise,
vibration and bearing temperatures are normal.
b) Check that there are no abnormal fluid or
lubricant leaks (static and dynamic seals) and
that any sealant systems (if fitted) are full and
operating normally.
c) Check that shaft seal leaks are within acceptable

c) The coupling should be checked for correct
alignment and worn driving elements.
equipment for periodic checks needed.
6.2.3
6.2.3.1
In general, VTPs that are product lubricated will not
require further periodic lubrication. Stuffing box and
mechanical seal needs flow of flush. Enclosed line
shaft pumps have to be provided with the required oil
quantity for an oil lubed system and the injection lube
flow at the required pressure for injection lubed
systems.
6.2.3.2
Refer to the manuals of any associated
Re-lubrication
Pump lubrication
Driver lubrication
Refer to driver manufacturer’s User
Instructions supplied with the pump.
Impeller re-adjustment
6.2.4
Ordinarily, impellers will not require re-adjustment if
properly set at initial installation.
All adjustments of the impellers will
change the seal setting, therefore, the seal must be
loosened from the shaft until the adjustment is
completed and then reset.
Maintenance of the stuffing box
6.2.5
6.2.5.1
Maintenance of the stuffing box will consist of greasing
the box when required, tightening the packing gland
occasionally as the leakage becomes excessive, and
installing new packing rings or sets as required.
6.2.5.2
Under ordinary operation, once-a-month greasing of
the stuffing box will be adequate. A high quality
industrial grade # 2 grease is recommended.
6.2.5.3
Remove gland and all old packing. If the box contains
a lantern ring, remove this and all packing below it
using two long threaded machine screws.
Inspect shaft or sleeve for score marks or rough spots.
Be sure by-pass holes (if supplied) are not plugged.
Repair or replace badly worn shaft or sleeve.
If wear is minor dress down until smooth and
concentric. Clean box bore.
Oil inside and outside of replacement rings lightly and
install in box, staggering joints 90 degrees. Be sure to
replace lantern ring in proper position when used.
Replace gland and tighten nuts finger tight. The
packing gland must never be tightened to the point
where leakage from the packing is stopped.
A small amount of leakage is required for packing
lubrication.
Packing ring sizes vary with the shaft diameter.
Packing ring size information are as follows.
General
Greasing the stuffing box

Examination of Parts
6.9
Used parts must be inspected before
assembly to ensure the pump will subsequently run
properly. In particular, fault diagnosis is essential to
enhance pump and plant reliability.
Before proceeding with assembly, thoroughly clean
all bolts, nuts, threaded connections and mating
faces. Clean up any burrs with a file or emery cloth.
Cleanliness and proper lubrication are
required to guarantee ease of re-assembly and
proper pump operation.
Page 51 of 76 flowserve.com
VERTICAL TURBINE PUMPS (VTPS) CENTRIFUGAL PUMPS ENGLISH 71569224 – 10-13
Examination of shaft/s
6.9.1
Check the shafts for straightness, pitting and wear.
Remove all burrs or nicks. Shaft damage is usually
best corrected by replacing the shaft.
The shaft must be straight to within 0.127 mm
(0.005 in.) total indicator reading. The detail below
shows the recommended method for checking shaft
straightness. If the shaft is not straight, it must be
straightened or replaced. If the deflection is gradual
over a considerable length, the shaft can usually be
straightened by supporting on two blocks straddling
the crooked section and applying pressure to the high
side to deflect the shaft in the opposite direction. If the
shaft has a sharp crook (dog-leg), it is recommended
that the shaft be replaced since the shaft will not
always remain straight, even if satisfactorily
straightened.
DIAL INDICATOR
ROLLERS
SHAFT
Even if the shaft is new or has been
previously straightened, it is recommended that the
shaft be re-checked at this point to ensure damage
has not occurred in transit or handling.
Examination of bearings
6.9.2
Check all bearings for total clearance over the shaft.
It is recommended that all bearings indicating visual
wear be replaced. In addition, any bearings whose
running clearance exceeds "As New" tolerances by
more than 50% should be replaced (see table 6.8.2.1).
Rubber bearings should always be replaced
when servicing a pump.

Bronze, epoxy, carbon and hard-backed rubber
bearings are pressed into their respective bores. They
can either be pressed out or machined on the inside
diameter until the wall is thin enough to collapse.
Some rubber bearings are the snap-in or glue-in type.
These can be removed by prying inward on the
outside of the bearing to collapse it.
If the bearing bore of the housing is heavily scarred or
corroded, the part should be replaced or reworked to
provide a true bore for the bearing.
Replacement bearings are designed to be pressed
into housings so bores will shrink to "as new"
tolerances. Measure the bore of bearings after
pressing and ream as necessary to assure "as new"
tolerances.
Inspection of bowl assembly
6.9.3
When repairing a bowl assembly that has
been in service for several years, the physical
condition or strength of all parts such as cap screws,
bowls and bowl threads must be carefully checked.
Page 52 of 76 flowserve.com
VERTICAL TURBINE PUMPS (VTPS) CENTRIFUGAL PUMPS ENGLISH 71569224 – 10-13
When attempting to rework any part,
extreme care must be taken to maintain alignment of
mating parts and ensure “as new” tolerances.
The inspection, disassembly of bowl assembly
requires expertise and tools to perform the job
correctly. It is recommended to seek the services of
Flowserve trained technicians to inspect and repair
bowl assemblies.
6.9.3.1
Inspection of enclosed impellers
a) Clear all passageways and check for signs of
damage from abrasion or corrosion. Replace an
impeller that shows signs of excessive wear.
b) Check impeller running clearances against “as
new” tolerances listed in the section 0. If the
clearances exceed the maximum tolerances
shown by more than 50%, the new wear rings
should be installed to obtain correct tolerances.
c) If the original unit was furnished with bowl and
impeller wear rings, they may be pressed or
machined off.
Please note that certain repairs may require special
skills and it is recommended to contact Flowserve
authorized service center before attempting any such
repairs.
See wear ring tolerance chart in section 0.
6.9.3.2
Inspection of semi-open impellers
a) Clear all passageways and check for signs of
damage from abrasion or corrosion.
b) Replace any impeller, which shows signs of
excessive wear. If the bowl faces or impellers
are worn slightly (grooves in either impeller or
bowl under 0.79 mm (1/32 in.)), they can be
corrected by re-facing the impeller and bowl.
0.79 mm (1/32 in.) is the maximum that can be
machined off without harm to the hydraulic
performance of the pump.
c) The machining must match the face angle and
should be re-faced by an authorized Flowserve
repair facility or replaced.
If the impeller has a balance ring on the topside
(side opposite pumping vanes) running clearances
must be checked.
Please see section 6.9.4 for wearing ring tolerance
chart for enclosed impellers.
