instructions where non-compliance in the hazardous
area would cause the risk of an explosion.
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.
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
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.
NEVER APPLY HEAT TO REMOVE IMPELLER
Trapped lubricant or vapour could cause an explosion.
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
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 (20 ºF) in a restricted zone, or exceeds
local regulations, action as above shall be taken.
Page 5 of 52 flowserve.com
USER INSTRUCTIONS POLYCHEM GRP ENGLISH 71569132 12-04A
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.
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.)
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 spacer
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 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.
Both electrical and non-electrical equipment must meet
the requirements of European Directive 94/9/EC.
1.6.4.1 Scope of compliance
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 OPERATE THE PUMP WITH
THE SUCTION VALVE CLOSED
It should be fully opened when the pump is running.
NEVER RUN THE PUMP DRY OR
WITHOUT PROPER PRIME (Casing Flooded)
NEVER OPERATE THE PUMP AT
ZERO FLOW OR FOR EXTENEDED PERIODS
BELOW THE MINIMUM CONTINUOUS FLOW
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 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 effects 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.

1.6.4.3 Avoiding excessive surface temperatures
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 ATEX temperature class and must not exceed the
values in the table that follows:
* The table only takes the ATEX temperature class into
consideration. Pump design or material, as well as component
design or material, may further limit the maximum working
temperature of the liquid.
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 when the pump is required to be
used in differently classified potentially explosive
atmospheres. In this case the user is responsible for
ensuring that the pump surface temperature does not
exceed that permitted in its actual installed location.
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 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 build up of explosive
mixtures
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
vapour 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.
Page 7 of 52 flowserve.com
USER INSTRUCTIONS POLYCHEM GRP ENGLISH 71569132 12-04A
To avoid the potential hazard from random induced
current generating a spark, the baseplate must be
properly grounded.
Avoid electrostatic charge: do not rub non-metallic
surfaces with a dry cloth; ensure cloth is damp.
For ATEX, 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 baseplates
When metallic components are fitted on a nonmetallic baseplate they must be individually earthed.
1.6.4.6 Preventing leakage
A pump with mechanical seal 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 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 Maintenance to avoid the hazard
1.7 Nameplate and safety labels
1.7.1 Nameplate
For details of nameplate, see the Declaration of
Conformity and section 3.
1.7.2 Safety labels
CORRECT MAINTENANCE IS REQUIRED TO
AVOID POTENTIAL HAZARDS WHICH GIVE A
RISK OF EXPLOSION
Oil lubricated units only:
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
DurcoShieldTM (splash/shaft guard
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.)

1.8 Specific machine performance
For performance parameters see section 1.5, Duty
conditions. Where performance data has been supplied
separately to the purchaser these should be obtained
and retained with these User Instructions if required.
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, 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 LpA at 1 m
(3.3 ft) from the machine, for “free field conditions
over a reflecting plane”.
For estimating sound power level LWA (re 1 pW) then
add 14 dBA to the sound pressure value.
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 in writing within one month 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 side
walls 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 fork lift vehicles or slings dependent on their
size and construction.
2.3 Lifting
A crane must be used for all pump sets in
excess of 25 kg (55 lb). Fully trained personnel must
carry out lifting, in accordance with local regulations.
The driver and pump weights are recorded on their
respective nameplates.
Pumps and motors often have integral
lifting lugs or eye bolts. These are intended for use in
only lifting the individual piece of equipment.
2.3.1.2 Rear cover [1220]
Use a choker hitch slung through the central seal
chamber hole to lift large rear covers.
2.3.1.3 Bearing housing [3200]
Group 1. Insert a sling between the upper and lower
support ribs between the housing barrel and the
casing attachment flange. Use a choker hitch when
slinging. (Make sure there are no sharp edges on the
bottom side of the ribs which could cut the sling.)
Group 2 and 3. Insert either a sling or hook through
the lifting lug located on the top of the housing.
2.3.1.4 Power end
Same as bearing housing.
2.3.1.5 Bare pump
Horizontal pumps. Sling under the casing and
around the outboard end of the bearing housing with
separate slings. Choker hitches must be used at
both attachment points and pulled tight. The sling
lengths should be adjusted to balance the load before
attaching the lifting hook.
2.3.2 Lifting pump, motor and baseplate assembly
If the baseplate has lifting holes cut in the sides at the
end (type A Group 3, type D, and type E bases) insert
lifting S hooks at the four corners and use slings or
chains to connect to the lifting eye. Do not use slings
through the lifting holes because of sharp edges.
Other styles of baseplates can be lifted by placing
slings slightly outboard from the center of mass of the
motor and pump. A spreader bar may be required to
maintain the sling spacing during lifting.
2.4 Storage
Do not use eye bolts or cast-in lifting
lugs to lift pump, motor and baseplate assemblies.
To avoid distortion, the pump unit
should be lifted as described in this section.
Care must be taken to lift components
or assemblies above the center of gravity to prevent
the unit from flipping.
2.3.1 Lifting pump components
2.3.1.1 Casing [1100]
Use a choker hitch through the suction hole and
around the casing body.
Page 10 of 52 flowserve.com
location away from vibration. Leave piping
connection covers in place to keep dirt and other
foreign material out of pump casing. Turn pump at
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 six
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:
Store the pump in a clean, dry
USER INSTRUCTIONS POLYCHEM GRP ENGLISH 71569132 12-04A
All loose unmounted items are packaged in a
waterproof plastic bag and placed under the
coupling guard. Larger items are boxed and
metal banded to the baseplate. For pumps not
mounted on a baseplate, the bag and/or box is
placed inside the shipping container.
Inner surfaces of the bearing housing, shaft (area
through bearing housing) and bearings are
coated with Cortec VCI-329 rust inhibitor, or
equal. (Note: bearing housings are not filled with
oil prior to shipment.)
Regreasable bearings are packed with grease.
(EXXON POLYREX EM for horizontal pumps.)
Exposed shafts are taped with Polywrap.
Flange covers are secured to both the suction
and discharge flanges.
Assemblies ordered with external piping, in some
cases components may be disassembled for
shipment.
The pump must be stored in a covered, dry location.
2.4.2 Long term storage
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.
After unpacking, protection will be the responsibility of
the user. Addition of oil to the bearing housing will
remove the inhibitor. 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 local requirements. If the
product contains substances that are harmful to the
environment, these should be removed and disposed
of in accordance with current 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
regulations at all times.

The pressure-temperature charts for PolyChem GRP
pumps are shown in figure 3-2. Maximum fluid
temperature for Derakane 470™ material is 121 °C
(250 °F) and for Durcon 730 is 107 °C (225 °F).
The following data are typical, and factors such as
liquid being pumped, temperature, and seal type may
influence them. If required, a definitive statement for
your application can be obtained from Flowserve.
3.4.2 Minimum continuous flow
The minimum continuous flow (MCF) is based on a
percentage of the best efficiency point (BEP). Figure
3-3 identifies the MCF for all PolyChem GRP pump
models.
3.4.3 Minimum suction pipe submergence
The minimum submergence is shown in figure 3-4 and
3-5 for the 1K3x2GS-7 unitized self-priming pump.
Figure 3-4: Minimum submergence
Figure 3-5: Minimum submergence
3.4.4 Suction pressure limits
Open style impellers typically create a thrust load
towards the suction of the pump. This reduces the axial
loading on the bearings so that the suction pressure
limit is equal to the pressure-temperature rating.
4 INSTALLATION
Equipment operated in hazardous locations
must comply with the relevant explosion protection
regulations. See section 1.6.4, Products used in
potentially explosive atmospheres.
4.1 Location
The pump should be located to allow room for access,
ventilation, maintenance and inspection with ample
headroom for lifting and should be as close as
practicable to the supply of liquid to be pumped. Refer
to the general arrangement drawing for the pump set.
4.2 Part assemblies
The supply of motors and baseplates is optional. As
a result, it is the responsibility of the installer to
ensure that the motor is assembled to the pump and
aligned as detailed in sections 4.5 and 4.8.
4.3 Foundation
4.3.1 Protection of openings and threads
When the pump is shipped, all threads and all
openings are covered. This protection/covering
should not be removed until installation. If, for any
reason, the pump is removed from service, this
protection should be reinstalled.
4.3.2 Rigid baseplates - overview
The function of a baseplate is to provide a rigid
foundation under a pump and its driver that maintains
alignment between the two. Baseplates may be
generally classified into two types:

2. Nuts
3. Lock washer
4. Floor cup
capability at the motor to obtain a “perfect” final
alignment when the installer puts the baseplate
assembly into its original, top leveled, unstressed
condition.
4.3.3 Stilt and spring mounted baseplates
Flowserve offers stilt and spring mounted baseplates.
Figure 4-1
(See Figure 4-2 for stilt mounted option.) The low
vibration levels of PolyChem GRP pumps allow the use
of these baseplates - provided they are of a rigid design.
The baseplate is set on a flat surface with no tie down
bolts or other means of anchoring it to the floor.
Figure 4-2
Baseplates intended for grouted installation are
designed to use the grout as a stiffening member.
Stilt mounted baseplates, on the other hand, are
designed to provide their own rigidity. Therefore, the
designs of the two baseplates are usually different.
Regardless of the type of baseplate used, it must
provide certain functions that ensure a reliable
installation. Three of these requirements are:
The baseplate must provide sufficient rigidity to
assure the assembly can be transported and
installed, given reasonable care in handling,
without damage. It must also be rigid enough
when properly installed to resist operating loads.
The baseplate must provide a reasonably flat
mounting surface for the pump and driver.
Uneven surfaces will result in a soft-foot condition
that may make alignment difficult or impossible.
Flowserve experience indicates that a baseplate
that has a top surface flatness of 1.25 mm/m
(0.015 in./ft) across the diagonal corners of the
baseplate provides such a mounting surface.
Therefore, this is the tolerance to which we supply
our standard baseplate. Some users may desire
an even flatter surface, which can facilitate
installation and alignment. Flowserve will supply
flatter baseplates upon request at extra cost. For
example, mounting surface flatness of 0.17 mm/m
General instructions for assembling these baseplates
are given below. For dimensional information, please
refer to the appropriate Flowserve “Sales Print.”
(Refer to figure 4-3.)
a) Raise or block up baseplate/pump above the floor
to allow for the assembly of the stilts.
b) Predetermine or measure the approximate
desired height for the baseplate above the floor.
c) Set the bottom nuts (item 2) above the stilt bolt
head (item 1) to the desired height.
d) Assemble lock washer (item 3) down over the stilt
bolt.
e) Assemble the stilt bolt up through hole in the
bottom plate and hold in place.
f) Assemble the lock washer (item 3) and nut (item 2)
on the stilt bolt. Tighten the nut down on the lock
washer.
g) After all four stilts have been assembled, position
the baseplate in place, over the floor cups (item 4)
under each stilt location, and lower the baseplate
to the floor.
h) Level and make final height adjustments to the
suction and discharge pipe by first loosening the
top nuts and turning the bottom nuts to raise or
lower the baseplate.
i) Tighten the top and bottom nuts at the lock
washer (item 3) first then tighten the other nuts.
(0.002 in./ft) is offered on the Flowserve Type E
“Ten Point” baseplate shown in figure 4-1.
The baseplate must be designed to allow the user
to final field align the pump and driver to within
their own particular standards and to compensate
for any pump or driver movement that occurred
during handling. Normal industry practice is to
achieve final alignment by moving the motor to
match the pump. Flowserve practice is to confirm
in our shop that the pump assembly can be
accurately aligned. Before shipment, the factory
verifies that there is enough horizontal movement

4.3.3.3 Stilt/spring mounted baseplates - motor
alignment
The procedure for motor alignment on stilt or spring
mounted baseplates is similar to grouted baseplates.
The difference is primarily in the way the baseplate is
leveled.
a) Level the baseplate by using the stilt adjusters.
(Shims are not needed as with grouted
baseplates.) After the base is level, it is locked in
place by locking the stilt adjusters.
b) Next the initial pump alignment must be checked.
The vertical height adjustment provided by the
stilts allows the possibility of slightly twisting the
baseplate. If there has been no transit damage
or twisting of the baseplate during stilt height
adjustment, the pump and driver should be within
0.38 mm (0.015 in.) parallel, and 0.0025 mm/mm
(0.0025 in./in.) angular alignment. If this is not
the case, check to see if the driver mounting
fasteners are centered in the driver feet holes.
c) If the fasteners are not centered there was likely
shipping damage. Re-center the fasteners and
perform a preliminary alignment to the above
tolerances by shimming under the motor for
vertical alignment, and by moving the pump for
horizontal alignment.
d) If the fasteners are centered, then the baseplate
may be twisted. Slightly adjust (one turn of the
adjusting nut) the stilts at the driver end of the
baseplate and check for alignment to the above
tolerances. Repeat as necessary while maintaining
a level condition as measured from the pump
discharge flange. Lock the stilt adjusters.
e) The remaining steps are as listed for new grouted
baseplates.
4.4 Grouting
a) The pump foundation should be located as close to
the source of the fluid to be pumped as practical.
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 base. (Refer to figure 4-5.)
Figure 4-5
USER INSTRUCTIONS POLYCHEM GRP ENGLISH 71569132 12-04A
baseplate or if they were not removed from the
Foundation bolts are imbedded in the
concrete inside a sleeve to allow some
movement of the bolt.
b) Level the pump baseplate assembly. If the
baseplate has machined coplanar mounting
surfaces, these machined surfaces are to be
referenced when leveling the baseplate. This may
require that the pump and motor be removed from
the baseplate in order to reference the machined
faces. If the baseplate is without machined
coplanar mounting surfaces, the pump and motor
are to be left on the baseplate. The proper
surfaces to reference when leveling the pump
baseplate assembly are the pump suction and
discharge flanges. DO NOT stress the baseplate.
Do not bolt the suction or discharge flanges of the
pump to the piping until the baseplate foundation
is completely installed. If equipped, use leveling
jackscrews to level the baseplate. If jackscrews
are not provided, shims and wedges should be
used (see figure 4-5). Check for levelness in both
the longitudinal and lateral directions. Shims
should be placed at all base anchor bolt locations,
and in the middle edge of the base if the base is
more than 1.5 m (5 ft) long. Do not rely on the
bottom of the baseplate to be flat. Standard
baseplate bottoms are not machined, and it is not
likely that the field mounting surface is flat.
c) After leveling the baseplate, tighten the anchor
bolts. If shims were used, make sure that the
baseplate was shimmed near each anchor bolt
before tightening. Failure to do this may result in
a twist of the baseplate, which could make it
impossible to obtain final alignment. Check the
level of the baseplate to make sure that
tightening the anchor bolts did not disturb the
level of the baseplate. If the anchor bolts did
change the level, adjust the jackscrews or shims
as needed to level the baseplate. Continue
adjusting the jackscrews or shims and tightening
the anchor bolts until the baseplate is level.
d) Check initial alignment. If the pump and motor
were removed from the baseplate proceed with
step e) first, then the pump and motor should be
reinstalled onto the baseplate using Flowserve’s
factory preliminary alignment procedure as
described in section 4.5, and then continue with
the following. As described above, pumps are
given a preliminary alignment at the factory. This
preliminary alignment is done in a way that
ensures that, if the installer duplicates the factory
conditions, there will be sufficient clearance
between the motor hold down bolts and motor foot
holes to move the motor into final alignment. If the
pump and motor were properly reinstalled to the
baseplate and there has been no transit damage,
and also if the above steps where done properly,
the pump and driver should be within 0.38 mm
(0.015 in.) FIM (Full Indicator Movement) parallel,
and 0.0025 mm/mm (0.0025 in./in.) FIM angular.
If this is not the case, first check to see if the driver
mounting fasteners are centered in the driver feet
holes. If not, re-center the fasteners and perform
a preliminary alignment to the above tolerances by
shimming under the motor for vertical alignment,
and by moving the pump for horizontal alignment.
e) Grout the baseplate. A non-shrinking grout
should be used. Make sure that the grout fills the
area under the baseplate. After the grout has
cured, check for voids and repair them.
Jackscrews, shims and wedges should be
removed from under the baseplate at this time. If
they were to be left in place, they could rust,
swell, and cause distortion in the baseplate.
f) Run piping to the suction and discharge of the
pump. There should be no piping loads
transmitted to the pump after connection is made.
Recheck the alignment to verify that there are no
significant loads.
4.5 Initial alignment
Pump and driver must be isolated
electrically and the half couplings disconnected.
The alignment MUST be checked.
4.5.1 Horizontal initial alignment procedure
The purpose of factory alignment is to ensure that the
user will have full utilization of the clearance in the
motor holes for final job-site alignment. To achieve
this, the factory alignment procedure specifies that
the pump be aligned in the horizontal plane to the
motor, with the motor foot bolts centered in the motor
holes. This procedure ensures that there is sufficient
clearance in the motor holes for the customer to field
align the motor to the pump, to zero tolerance. This
philosophy requires that the customer be able to
place the base in the same condition as the factory.
Thus the factory alignment will be done with the base
sitting in an unrestrained condition on a flat and level
surface. This standard also emphasizes the need to
ensure the shaft spacing is adequate to accept the
specified coupling spacer.
The factory alignment procedure is summarized
below:
a) The baseplate is placed on a flat and level
workbench in a free and unstressed position.
