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

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 68 ºC (175 ºF) or
below 5 ºC (20 ºF) in a restricted zone, or exceeds
local regulations, action as above shall be taken.
NEVER APPLY HEAT TO REMOVE IMPELLER
This could damage the liner plus trapped lubricant or
vapor could cause an explosion.

1.6.4 Products used in potentially explosive
THERMAL SHOCK
atmospheres
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.
The following instructions for pumps and pump
units when installed in potentially explosive
atmospheres must be followed to help ensure
explosion protection. The terminology and
HAZARDOUS LIQUIDS
When the pump is handling hazardous liquids care must
be taken to avoid exposur e to the l iquid by approp riate

operator training. If the liquid is flammable and or
explosive, strict safety procedures must be applied.
procedures ensure that the installed pump is in
compliance with the European Directive 94/9/EC,
known as the ATEX Directive, which is mandatory in
Europe and may also be specified in other countries.
Where applicable, both electrical and non-electrical
equipment must meet the requirements 94/9/EC.

not the applicable regulation, the general measures
described shall be followed to ensure safe operation.
The measures are explained under the headings of:
• Avoiding excessive surface temperature
• Preventing build up of explosive mixtures
• Preventing the generation of sparks
• Preventing leakages
• Maintaining the pump to avoid hazard
1.6.4.1 Scope of compliance
Use equipment only in the zone for whi ch it is
appropriate. Always check that the driver , drive
coupling assembly, seal and pump equipment are
suitably rated and/or certifie d for the classi fication of the
specific atmosphere in which they are to be inst alled.
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/
NEVER RUN THE PUMP DRY OR
WITHOUT PROPER PRIME (Casing flooded)
Declaration of Conformity establishing it is suitable for
the area in which it is to be installed.
NEVER OPERATE THE PUMP WITH
THE SUCTION VALVE CLOSED
It should be fully opened when the pump is running.
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
NEVER OPERATE THE PUMP AT
ZERO FLOW OR FOR EXTENDED PERIODS
BELOW THE MINIMUM CONTINUOUS FLOW
where electrical supply is from the VFD. This
particular requirement still applies even if the VFD is
in a safe area.
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 spa cer
and starting the pump. Incorrect rotation of the pump
for even a short period can unscrew the impeller,
which can cause significant damage.

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

The responsibility for compliance with the
specified maximum liquid temperature is with the
plant operator.
Temperature classification “Tx” is used when the liquid
temperature varies and when the pump is requir ed 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 installe d location.
Do not attempt to check the direction of rotation with the
coupling element/pins fitted due to the risk of sev ere
contact between rotating and stationary compo nents.
Where there is any risk of the pump being run against a
closed valve generating high liqui d and casing exte rnal
surface temperatures it is recommended that users fit
an external surface temperature protectio n device.
Avoid mechanical, hydraulic or electrical overlo ad by
using motor overload trips, temperature monitor or a
power monitor and perform rout ine vibrat ion monito ring.
In dirty or dusty environments, regular checks must
be made and dirt removed 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 the fitting of an appropriate dry run
protection device is recommended (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.

USER INSTRUCTIONS POLYCHEM S-SERIES ENGLISH 71569207 11-08
1.6.4.5 Preventing sparks
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 earth contact on the
baseplate must be used.
Avoid electrostatic charge: do not rub no n-metallic
surfaces with a dry cloth; en sure cloth is dam p.
When applicable the coupling must be selected to
comply with 94/9/EC and correct 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
The pump must only be used to handle liquids
for which it has been approved to have the correct
corrosion resistance.
Avoid entrapment of liquid in the pump a nd associat ed
piping due to closing of su ction an d discharg e valves,
which could cause dangerous excessiv e pressures to
occur if there is heat input t o the liqu id. This ca n 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 lo ss of a seal
barrier fluid or external flush, the f luid must be monit ored.
If leakage of liquid to atmosphere can result in a
hazard, the installation of a liquid detection device is
recommended.
1.6.4.7 Maintenance of the centrifugal pump to
avoid a hazard
CORRECT MAINTENANCE IS REQUIRED TO
AVOID POTENTIAL HAZARDS WHICH GIVE A
RISK OF EXPLOSION
The responsibility for compliance of maintenance
and compliance during mainten ance with the
specified product is with the plant operator.
To avoid potential explosion hazards during
maintenance, the tools, cleaning and painting
materials used must not give rise to sparking or
adversely affect the ambient conditions. Where there
is a risk from such tools or materials, maintenance
must be conducted in a safe area.
It is recommended that a maintenance plan and
schedule is adopted. (See section 6, Maintenance.)

1.8 Specific machine performance
For performance parameters see section 1.5, Dut y
conditions. Where performance data has been supplied
separately to the purchaser these should be obtained
and retained with these User Inst ructions if re quired.
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 a ssumed in t he “pump and
motor” noise is that typically exp ected f rom stand ard
and high efficiency motors when on load dire ctly 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 Flowserv e 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 1 pW) then
WA
add 14 dBA to the sound pressure value.

in transportation. Any shortage and or damage must
be reported immediately to Flowserve and must be
received in writing within thirty (30) calendar days of
receipt of the equipment. Later claims cannot be
accepted.
Check any crate, boxes or wrappings for any
accessories or spare parts that may be packed
separately with the equipment or attached to 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
Pumps and motors often have integral
lifting lugs or eye bolts. These are intended for use in
only lifting the individual piece of equipment.

sure the completion of the choker hitch on the discharge
nozzle is toward the coupling end of the pump shaft as
shown in Figure 2-1. The sling lengths should be
adjusted to balance th e load bef ore att achi ng the lift ing

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 shown.
Care must be taken to lift components or
assemblies above the center of gr avity to prev ent the
unit from flipping. This is especially t rue with In -Line
pumps.

2.3.2 Lifting pump, motor and baseplate assembly
If the baseplate has lifting holes cut in the sides at the
end (Type D and Type E base s) insert lifti ng S hook s at
the four corners and use slings or chains to connect to
the lifting eye. (Figure 2-1.) Do not use slings through
the lifting holes.
For other baseplates, sling around the pump discharge
nozzle, and around the outboard end of the motor
frame using choker hitches pulled tight. Pump models
with non standard flanges can not accommodate a
sling around the discharge nozzle; when lifting these
pumps an individual trained in properly lifting
equipment must be consulted. (Figure 2-1.)
The sling should be positioned so the weight is not
carried through the motor fan housing. Make sure the
completion of the choker hitch on the discharge
nozzle is toward the coupling end of the pump shaft
as shown in Figure 2-1.
2.4 Storage
Store th e pump in a clea n, dry locati on
away from vibration. Leave piping connectio n covers in
place to keep dirt and other foreign material out of pump
casing. T urn pump at int erv als to pr event brinel ling of
the bearings and the seal faces, if fitted, from sticking.
The pump may be stored as above for up to 6
months. Consult Flowserve for preservative actions
when a longer storage period is needed.
2.4.1 Short term storage and packaging
Normal packaging is designed to protect the pump
and parts during shipment and for dry, indoor storage
for up to six months or less. The following is an
overview of our normal packaging:
• All loose unmounted items are packaged in a
water proof plastic bag and placed under the
coupling guard
• Inner surfaces of the bearing housing, shaft (area
through bearing housing) and bearings are coated
with Cortec VCI-329 rust inhibitor, or equal.
2.4.2 Long term storage and packaging
Long term storage is defined as more than six
months, but less than 12 months. The procedure
Flowserve follows for long term storage of pumps is
given below. These procedures are in addition to the
short term procedure.
• Each assembly is hermetically (heat) sealed from
the atmosphere by means of tack wrap sheeting
and rubber bushings (mounting holes)
• Desiccant bags are placed inside the tack
wrapped packaging
• A solid wood box is used to cover the assembly
This packaging will provide protection for up to twelve
months from humidity, salt laden air, dust etc.
After unpacking, protection will be the responsibility of
the user. Addition of oil to the bearing housing will
remove the inhibitor. If unit s are to be idle fo r extende d
periods after addition of lubricants, in hibitor oils a nd
greases should be used. Every three months, the pump
shaft should be rotated approximately 10 revolution s.
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.
Bearing housings are not filled with oil
prior to shipment
• Regreasable bearings are packed with grease
(MOBIL POLYREX EM)
• Exposed shafts are taped with Polywrap
• Flange covers are secured to both the suction
and discharge flanges
• In some cases with assemblies ordered wit h
external piping, components may be
disassembled for shipment
• The pump must be stored in a covered, dry location

4 INSTALLATION
Equipment operated in hazardous locations
must comply with the relevant explosion protection
regulatiuons. See section 1.6.4, Products used in
potentially explosive atmospheres.
4.1 Location
The pump should be located to allow room for acce ss,
ventilation, maintenance, and inspe ction 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 are 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 section 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:
• Foundation-mounted, grouted de sign. (Figure 4-1. )
• Stilt mounted, or free standing. (Figure 4-2.)
Figure 4-1
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.
Page 14 of 52 flowserve.com
USER INSTRUCTIONS POLYCHEM S-SERIES ENGLISH 71569207 11-08
Experience indicates that a baseplate with 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
(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 a nd drive r to within th eir
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 confir m in our shop
that the pump assembly can be accurately aligned.
Before shipment, the factory verifies that there is
enough horizontal movement capability at the motor
to obtain a “perfect” final alig nment wh en the
installer puts the baseplate assembly into its
original, top levelled, unstressed conditi on.
4.3.3 Stilt and spring mounted baseplates
Flowserve offers stilt and spring mounted baseplates.
(See Figure 4-2 for stilt mounted option.) The low
vibration levels of PolyChem 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.
General instructions for assembling these baseplates
are given below. For dimensional information, please
refer to the appropriate Flowserve “Sales print”.
4.3.3.1 Stilt mounted baseplate assembly
instructions
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 [2] above the stilt bolt head
[1] to the desired height.
d) Assemble lock washer [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 [3] and nut [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 [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 [3] first then tighten the other nuts.
j) It should be noted that the connecting pipelines
must be individually supported, and that the stilt
mounted baseplate is not intended to support
total static pipe load.

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
levelled.
a) Level the baseplate by using the stilt adjusters.
(Shims are not needed as with grouted baseplates.)
b) After the base is level, it is locked in place by
locking the stilt adjusters.
c) 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.
d) 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.
e) 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.
f) Lock the stilt adjusters.
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.
b) 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.
c) Recommended mass of a concrete foundation
should be three times that of the pump, motor
and base. Refer to Figure 4-5.
Foundation bolts are imbedded in the
concrete inside a sleeve to allow some
movement of the bolt.
Figure 4-5
d) Level the pump baseplate assembly. If the
baseplate has machined coplanar mounti ng
surfaces, these machined surfaces are to be
referenced when leveling the baseplate. This may
require that the pump and motor b e remove d 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 p roper surfa ces
to reference when leveling the pump baseplate
assembly are the pump suction and discharge
flanges. DO NOT stress the baseplate.
e) Do not bolt the suction or discharge flanges of the
pump to the piping until the ba seplate f oundati on 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 levelne ss 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 i s more than
1.5 m (5 ft.) long. Do not rely on th e bottom of t he
baseplate to be flat. Standard baseplate bottoms
are not machined, and it is not likely that the field
mounting surface is flat.
