FM USER INSTRUCTIONS ENGLISH 71576526 - 03/07  
1.6.3 Safety action  
1.6 Safety  
This is a summary of conditions and actions to  
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.  
1.6.1 Summary of safety markings  
These User Instructions contain specific safety  
markings where non-observance of an instruction  
would cause hazards. The specific safety markings  
are:  
NEVER DO MAINTENANCE WORK  
WHEN THE UNIT IS CONNECTED TO POWER  
This symbol indicates electrical safety  
instructions where non-compliance will involve a  
high risk to personal safety or the loss of life.  
GUARDS MUST NOT BE REMOVED WHILE  
THE PUMP IS OPERATIONAL  
This symbol indicates safety instructions where  
non-compliance would affect personal safety and  
could result in loss of life.  
DRAIN THE PUMP AND ISOLATE  
PIPEWORK BEFORE DISMANTLING THE PUMP  
The appropriate safety precautions should be taken  
where the pumped liquids are hazardous.  
This symbol indicates “hazardous substances  
and toxic fluid” safety instructions where non-  
compliance would affect personal safety and could  
result in loss of life.  
FLUORO-ELASTOMERS (When fitted.)  
When a pump has experienced temperatures over  
250 ºC (482 ºF), partial decomposition of fluoro-  
elastomers (example: Viton) will occur. In this  
condition these are extremely dangerous and skin  
contact must be avoided.  
This symbol indicates safety  
instructions where non-compliance will involve some  
risk to safe operation and personal safety and would  
damage the equipment or property.  
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 indicates explosive atmosphere  
zone marking according to ATEX. It is used in safety  
instructions where non-compliance in the hazardous  
area would cause the risk of an explosion.  
This symbol is used in safety instructions to  
remind not to rub non-metallic surfaces with a dry  
cloth; ensure cloth is damp. It is used where non-  
compliance in the hazardous area would cause the  
risk of an explosion.  
THERMAL SHOCK  
Rapid changes in the temperature of the liquid within  
the pump can cause thermal shock, which can result  
in damage or breakage of components and should  
be avoided.  
NEVER APPLY HEAT TO REMOVE  
IMPELLER  
Trapped lubricant or vapor could cause an explosion.  
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.  
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.  
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.  
If the temperature is greater than 68 °C (175 °F)  
or below 5 °C (20 °F) in a restricted zone, or  
exceeds local regulations, action as above shall  
be taken.

FM USER INSTRUCTIONS ENGLISH 71576526 - 03/07  
1.6.4 Products used in potentially explosive  
atmospheres  
HAZARDOUS LIQUIDS  
When the pump is handling hazardous liquids care  
must be taken to avoid exposure to the liquid by  
appropriate sitting of the pump, limiting personnel  
access and by operator training. If the liquid is  
flammable and/or explosive, strict safety procedures  
must be applied.  
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 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.  
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.  
Even if the installation is in a region where ATEX is not  
the applicable regulation, the general measures  
described shall be followed to ensure safe operation.  
The measures are explained under the headings of:  
ENSURE CORRECT LUBRICATION  
(See section 5, Commissioning, startup, operation  
and shutdown.)  
Avoiding excessive surface temperature  
Preventing build up of explosive mixtures  
Preventing the generation of sparks  
Preventing leakages  
START THE PUMP WITH OUTLET  
VALVE PART OPENED  
Maintaining the pump to avoid hazard  
(Unless otherwise instructed at a specific point in the  
User Instructions.)  
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.  
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. Pump outlet valve shall may need to  
be adjusted to comply with the duty following the  
run-up process. (See section 5, Commissioning  
start-up, operation and shutdown.)  
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 Declaration of  
Conformity establishing it is suitable for the area in  
which it is to be installed.  
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 seal.  
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 backpressure on the pump may  
overload the motor and cause cavitation. Low flow  
rates may cause a reduction in pump/bearing life,  
overheating of the pump, instability and  
cavitation/vibration.

FM USER INSTRUCTIONS ENGLISH 71576526 - 03/07  
1.6.4.2 Marking  
The responsibility for compliance with the  
specified maximum liquid temperature is with the  
plant operator.  
An example of ATEX equipment marking is shown  
below. The actual classification of the pump will be  
engraved on the nameplate.  
Temperature classification “Tx” is used when the  
liquid temperature varies and the pump could be  
installed in different hazardous atmospheres. In this  
case the user is responsible for ensuring that the  
pump surface temperature does not exceed that  
permitted in the particular hazardous atmosphere.  
II 2 GD c IIC 135 ºC (T4)  
Equipment Group  
I = Mining  
II = Non-mining  
If an explosive atmosphere exists during the  
Category  
2 or M2 = High level protection  
3 = normal level of protection  
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. Furthermore, confinement of liquid in  
the pump and pipes must be avoided (valve closed).  
If the liquid heats up this may cause excessive  
pressure and lead to bursting of pump components.  
Gas and/or Dust  
G = Gas; D= Dust  
c = Constructional safety  
(in accordance with EN 13463-5)  
Gas Group (Equipment Category 2 only)  
IIA – Propane (typical)  
IIB – Ethylene (typical)  
Where there is any risk of the pump being run against  
a closed valve generating high liquid and casing  
external surface temperatures it is recommended that  
users fit an external surface temperature protection  
device.  
IIC – Hydrogen (typical)  
Maximum surface temperature (Temperature Class)  
(see section 1.6.4.3)  
Avoid mechanical, hydraulic or electrical overload by  
using motor overload trips, temperature monitor or a  
power monitor and make routine vibration monitoring  
checks.  
1.6.4.3 Avoiding excessive surface temperatures  
ENSURE THE EQUIPMENT TEMPERATURE  
CLASS IS SUITABLE FOR THE HAZARD ZONE  
In dirty or dusty environments, regular checks must  
be made and dirt removed from areas around close  
clearances, bearing housings and motors.  
Pumps have a temperature class as stated in the  
ATEX Ex rating on the nameplate. These are based  
on a maximum ambient of 40 °C (104 °F); refer to  
Flowserve for higher ambient temperatures.  
1.6.4.4 Preventing the build up of explosive  
mixtures  
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.  
ENSURE PUMP IS PROPERLY FILLED AND  
VENTED AND DOES NOT RUN DRY.  
Ensure 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.  
The temperature rise at the seals, bearings and due  
to the minimum permitted flow rate is taken into  
account in the temperatures stated.

FM USER INSTRUCTIONS ENGLISH 71576526 - 03/07  
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.)  
1.6.4.5 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 ground contact on the  
baseplate must be used.  
1.7 Nameplate and safety labels  
1.7.1 Nameplate  
For details of nameplate, see the Declaration of  
Conformity, or separate documentation included with  
these User Instructions.  
Avoid electrostatic charge: do not rub non-  
metallic surfaces with a dry cloth, ensure cloth is  
damp.  
Where applicable the coupling must be selected to  
comply with 94/9/EC and correct alignment must be  
maintained.  
1.7.2 Safety labels  
Additional requirements for metallic pumps on  
non-metallic baseplates  
When metallic components are fitted on a non-  
metallic baseplate they must be individually earthed  
(grounded).  
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 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.  
Oil lubricated units only:  
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, the installation of a liquid detection device is  
recommended.  
1.8 Specific machine performance  
For performance parameters see section 1.5, Duty  
conditions. When the contract requirement specifies  
these to be incorporated into User Instructions these  
are included here. Where performance data has  
been supplied separately to the purchaser these  
should be obtained and retained with these User  
Instructions if required.  
1.6.4.7 Maintenance to avoid the hazard  
CORRECT MAINTENANCE IS REQUIRED  
TO AVOID POTENTIAL HAZARDS WHICH GIVE A  
RISK OF EXPLOSION  
The responsibility for compliance with  
maintenance instructions is with the plant  
operator.  
To avoid potential explosion hazards during  
maintenance, the tools, cleaning and painting  
materials used must not give rise to sparking or  
adversely affect the ambient conditions.

FM USER INSTRUCTIONS ENGLISH 71576526 - 03/07  
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.  
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.  
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.  
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.  
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”.  
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.  
For estimating sound power level LWA (re 1 pW)  
then add 17 dBA to the sound pressure value.

FM USER INSTRUCTIONS ENGLISH 71576526 - 03/07  
In areas where the staff has to intervene, remember  
that when the level of the sound pressure is:  
To lift machines or pieces with one or several  
suspension rings, only use hooks and chains in  
compliance with the local regulations concerning  
safety.  
below 70 dBA: it is not necessary to take special  
precautions.  
above 70 dBA: people working continuously in  
the machine room must be supplied with  
protective devices against noise.  
below 85 dBA: no particular measures need to  
be taken for casual visitors staying in the room  
during a limited period.  
above 85 dBA: the room must be considered as  
a dangerous area because of the noise and a  
warning sign must be fixed at each entry  
warning the people coming into the room, even  
for a short period, that they must wear hearing  
protection.  
Never put cables, chains or ropes directly on or in  
the suspension rings. Cables, chains or lifting ropes  
must never present excessive bending.  
Never bend the lifting hooks, suspension rings,  
chains, etc... which should only be made to endure  
stresses within calculated limits. Remember that the  
capacity of a lifting device decreases when the  
direction of the lifting force direction makes an angle  
with the device axis.  
To increase the safety and the efficiency of the lifting  
device, all the lifting elements must be as  
perpendicular as possible. If necessary a lifting  
beam can be placed between the winch and the  
load.  
above 105 dBA: special hearing protection  
adapted to this noise level and to the spectral  
noise components must be installed and a  
warning sign to this effect erected at each entry.  
The staff in the room must wear ear protection.  
When heavy pieces are lifted up, never stay or work  
under the load or in the area which could be in the  
path of the load if it were to swing or fall away.  
Make sure that the noise, which travels through the  
walls and windows, does not generate too high  
noise levels in the machine room's surroundings.  
Never leave a load hanging from a winch. The  
acceleration or the slowing-down of lifting equipment  
must stay in the safety limits for the staff.  
2 TRANSPORT AND STORAGE  
2.1 Consignment receipt and unpacking  
Immediately after receipt of the equipment it must be  
checked against the delivery and shipping  
documents for its completeness and that there has  
been no damage in transportation.  
A winch must be positioned in such a way that the  
load will be raised perpendicularly. Where possible  
necessary precautions must be taken to avoid the  
swing of the load, using for example two winches  
making approximately the same angle, below 30°,  
with the vertical.  
Any shortage and or damage must be reported  
immediately to the Flowserve and received in writing  
within one month of receipt of the equipment. Later  
claims cannot be accepted.  
2.2.2 Pump masses

3 PUMP DESCRIPTION  
Motor pump unit  
3.1 Description and restrictions of use  
The multi-stage centrifugal pump is designed for the  
pumping of cold water or all clear liquids which are  
not solid and liquid mixtures, non-corrosive, non-  
abrasive or non-explosive when in contact with the  
pump motor unit and its working parts (Important: for  
other liquids consult Flowserve for beforehand  
advice).  
The FM type is a centrifugal, multi-stage, close-  
coupled pump with an axial inlet and a vertical axis  
outlet.  
The pump must be stored in a non explosive,  
ventilated location, sheltered from bad weather, dust  
and vibrations.  
When handling always wear gloves, safety  
boots and an industrial safety helmet.  
For masses above 25 kg (55 lb), manual  
handling is forbidden.  
2.4 Storage  
Store the pump in a clean, dry  
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 reliability of the delivered machine can only be  
ensured if it is used according to the conditions  
given in this manual. The maximum values specified  
in this manual must never be exceeded.  
Do not store pumps starting on the fan guard.  
The pump may be stored as above for up to 6  
months. Consult Flowserve for preservative actions  
when a longer storage period is needed.

or on the discharge flange with a levelling  
instrument.  
b) Admissible defect 0.5 mm for 1 meter (0.02 in  
for 3.3 ft).  
c) Wedge under the pump.  
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.  
All equipment must be grounded.  
Level  
Frame  
level  
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.  
4.3 Piping  
The user must verify that the equipment is  
isolated from any external sources of vibration.  
Protective covers are fitted to the  
pipe connections to prevent foreign bodies entering  
during transportation and installation. Ensure that  
these covers are removed from the pump before  
connecting any pipes.  
4.3.1 Suction and discharge piping  
The dimensions of the pipes do not directly depend  
on suction and discharge diameters of the pump:  
a) First, choose a flow speed < 2 m/s (7 ft/s) at  
suction, and about 3 m/s (10 ft/s) at discharge.  
b) Take into account the available NPSH, which  
must be superior to the required NPSH of the  
pump.  
4.2 Foundation  
There are many methods of installing  
pump units to their foundations. The correct method  
depends on the size of the pump unit, its location  
and noise vibration limitations. Non-compliance with  
the provision of correct foundation and installation  
may lead to failure of the pump and as such would  
be outside the terms of the warranty.  
Anchor bolts must be appropriate for the foot bolt  
holes. Use anchor bolts of accepted standards and  
sufficient length so that they may be clamped safely  
in the grout.  
Never use pump as a support for  
piping.  
Do not mount expansion joints in  
such a way that their force, due to internal pressure,  
may act on the pump flange.  
Maximum forces and moments allowed on the pump  
flanges vary with the pump size and type. These  
external strains may cause misalignment, heating of  
the bearings, vibrations and the possible failure of  
the pump casing.  
When designing the pipework (§ 5.3.1, § 5.3.2, §  
5.3.3) take necessary precautions in order not to  
exceed maximum allowed strains.  
NF E 27 811  
Provide sufficient space in the foundation to  
accommodate the anchor bolts. If necessary, provide  
concrete gullets.  
Forces and moments applied to the pump flanges  
must never exceed the values shown in the following  
table:

FM USER INSTRUCTIONS ENGLISH 71576526 - 03/07  
The non-return valve will be set in the discharge  
pipe to protect the pump from any excessive  
pressure surge and from reverse rotation.  
It is important to be aware of the EUROPEAN  
DIRECTIVE on electromagnetic compatibility when  
wiring up and installing equipment on site. Attention  
must be paid to ensure that the techniques used during  
wiring/installation do not increase electromagnetic  
emissions or decrease the electromagnetic immunity of  
the equipment, wiring or any connected devices. If in  
doubt, contact Flowserve for advice.  
If necessary, a control manometer (pressure gauge)  
can be connected on the piping.  
Before connecting the electric power supply, if the  
device has been kept in a damp atmosphere, have  
the insulation resistance of the electric motor  
checked.  
Control manometer  
This resistance should have a value of not less than  
5 000 ohms for each volt of the supply.  
Carry out the ground connections according to the  
current local regulations.  
Setting of the control manometer  
The motor must be protected. The protection must  
therefore be ensured by a magneto thermal breaker  
located between the section switch and the motor.  
Do not tighten flanges before the final  
check (see § 4.3.4).  
This breaker can be connected to fuses.  
Never connect the electric motor  
before the setting has been completely finished.  
Use a breaker sized and provisionally adjusted to  
the current specified on the description plate.  
4.3.4 Final checks  
a) Check the tightening of anchor bolts. Tighten  
It is recommended to provide the power supply of  
the electric motor with a monitoring device allowing  
the machine to be shut down safely.  
them if necessary.  
b) Check that protective covers on suction and  
discharge flanges are removed.  
c) Check that holes of piping flanges are parallel  
and correspond to those of the pump.  
d) Tighten suction and discharge flanges.  
e) If it is planned, connect piping (hydraulic,  
pneumatic, sealing system).  
A device to provide emergency stopping shall be  
fitted.  
4.4.2 Electrical supply  
Make sure that the voltage of the electrical supply  
line is correct for that specified on the motor  
description plate.  
f) Control seal and the working of auxiliary piping.  
4.4 Electrical connections  
Make sure that the supply wires have sufficient load  
capacity for the correct running of the installation.  
4.4.1 Safety conditions about electrical  
connections  
4.4.3 Wiring Instructions  
The motors are closed type IP 55 class E - 50 Hz  
Electric connections must be carried  
out by a qualified electrician, following the local rules  
and regulations in force.  
230/ 400 V up to 3.7 kW - 50 H:  
The motors can be directly supplied with 230 or  
400 V according to the coupling (starting with  
230 V is possible but not advised)  
It is important to be aware of the EUROPEAN  
DIRECTIVE on potentially explosive areas where  
compliance with IEC60079-14 is an additional  
requirement for making electrical connections.  
400 V from 5.5 kW - 50 Hz:  
The motors can be directly supplied with 400 V  
(starting with 400 V is possible but not  
advised). Astatoric start is advised.

Connection wiring diagram for three phase motors:  
5 COMMISSIONING START-UP,  
OPERATION AND SHUTDOWN  
These operations must only be carried out  
by qualified personnel.  
5.1 Direction of rotation  
Delta connection  
Star connection  
Starting or operating pumps with the  
wrong direction of rotation can be harmful to the  
pumps. Ensure that the pump rotation is the same  
as the arrow on the pump casing.  
Wire up the motor terminals according to the voltage  
supply, in accordance with the description plate fixed  
on the motor and with the connection wiring diagram  
mentioned on the terminal box as opposite.  
It is preferable to check the direction of rotation  
before installing the coupling. If not, the pump must  
be filled in with the liquid before start-up.  
To avoid any risk of jamming, the  
direction of rotation will be checked after priming of  
the pump (§ 5.3.1, 5.3.2) and before the first start (§  
5.4.2).  
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.  
4.5 Protection systems  
The following protection systems are  
recommended particularly if the pump is installed in  
a potentially explosive area or is handling a  
hazardous liquid. If in doubt consult Flowserve. If  
there is any possibility of the system allowing the  
pump to run against a closed valve or below  
minimum continuous safe flow a protection device  
should be installed to ensure the temperature of the  
liquid does not rise to an unsafe level.  
5.2 Guarding  
Guarding is supplied fitted to the pump set.  
If this has been removed or disturbed ensure that all  
the protective guards around the pump coupling and  
exposed parts of the shaft are securely fixed.  
5.3 Priming and auxiliary supplies  
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.  
Where there is any risk of the pump being run  
against a closed valve generating high liquid and  
casing external surface temperatures it is  
recommended that users fit an external surface  
temperature protection device.  
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.  
Ensure all 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.  
To prevent excessive surface temperatures at  
bearings it is recommended that temperature or  
vibration monitoring are carried out. See sections  
5.5.4 and 5.5.5.  
These operations must be carried out by personnel  
with approved qualifications.  
If a defect of cooling can lead to temperature higher  
than those acceptable a system of cooling  
surveillance must be installed.  
5.3.1 Priming of a flooded pump  
a) Close the discharge valve, fill the pump by  
opening the suction valve. Let air escape by  
removing the plug located on the piping.  
b) The discharge pipe is headed and there is a by-  
pass valve on the check valve, open slightly the  
discharge valve and the by-pass of the check  
valve.  
Except when explicitly required by the customer in  
the specifications, when a possibility of reverse  
rotation exists the customer must install a reverse  
rotation protection device.  
The customer must install all equipment required to  
avoid water hammer.  
c) When the pump is totally free of air bubbles,  
replace the plugs.

5.4.2 First pump start-up  
a) Fill suction pipe and casing with liquid from an  
independent source (pressure 1 to 2 bars or 15  
to 30 psi).  
b) Let air escape by removing the plugs located on  
the piping.  
Suction valves must be fully open  
when pump is running. Never run the pump dry, it  
will cause damage.  
c) When the pump is totally free of air bubbles,  
replace the plugs.  
a) Start motor and check outlet pressure.  
b) If pressure is satisfactory, slowly OPEN the  
outlet valve.  
Air escape  
c) Do not run the pump with the outlet valve closed  
for a period longer than 30 seconds.  
d) If NO pressure, or LOW pressure, STOP the  
pump. Refer to fault finding chart for fault  
diagnosis.  
External source  
The pump should run smoothly and without  
vibration.  
The pump must never run at a capacity less than  
10 % of the best efficiency point.  
Never remove a plug when the pump is  
running.  
Priming of a sump suction configuration  
with foot valve  
5.5 Running the pump  
5.5.1 Venting the pump  
* Without foot valve:  
Priming may be accomplished by means of venting  
system.  
Vent the pump to enable all trapped air to  
escape taking due care with hot or hazardous  
liquids.  
Foot valves are not recommended when  
the pumped liquid has suspended solid particles.  
They may lodge between foot valve seat and  
shutter.  
Under normal operating conditions, after the pump  
has been fully primed and vented, it should be  
unnecessary to re-vent the pump.

5.5.2 Pump fitted with a stuffing box  
2445  
4200  
4213  
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. 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 it should be checked to  
ensure leakage is taking place at the packed gland.  
When adjusting an operating stuffing box  
(shield grids removed for this operation), the  
operator must be very careful. Safety gloves are  
compulsory and loose clothes are not allowed  
(above all to the arms) to avoid being caught by the  
pump shaft.  
4610  
4240  
With a mechanical seal, the  
maximum temperature is limited to 80 °C (176 °F)  
whatever the internal construction of the pump is  
(Cast iron or Bronze).  
The pump should be run for ten minutes with steady  
leakage and the gland nuts tightened by 10 degrees  
at a time until leakage is reduced to an acceptable  
level.  
NEVER RUN A MECHANICAL SEAL  
DRY, EVEN FOR A SHORT WHILE.  
The temperature of the gland should be checked  
after each round of tightening. If the temperature  
starts to climb rapidly then back off the gland nuts  
until the temperature drops down. Wait for the  
temperature to stabilize before tightening again.  
SAFETY INSTRUCTIONS WHEN THE PUMP IS  
RUNNING:  
If hot or freezing components of the machine  
can present a danger to operators, they must be  
shielded to avoid accidental contact. If a 100 %  
protection is not possible, the machine access must  
be confined to the maintenance staff only.  
The leakage must not be reduced below a rate of 20  
drops per minute. Bedding in of the packing may  
take several hours.  
If the temperature is greater than 80 °C (176  
°F), a warning plate must be clearly placed on the  
pump.  
It is strictly forbidden to open switch  
cupboards, switch boxes, or all other live electric  
equipment. If it is necessary to open them in order to  
take readings, to carry out tests or adjustments for  
example, only a skilled technician may do them with  
adapted tools. Make sure that physical protections  
against electrical risks are used.  
5.5.4 Bearings  
Shield grids being removed during installation  
of the gland packing, it must be ensured that they  
are replaced as soon as this operation is completed.  
If the pumps are working in a potentially  
explosive atmosphere, temperature or vibration  
monitoring at the bearings is recommended. If  
bearing temperatures are to be monitored it is  
essential that a benchmark temperature is recorded  
at the commissioning stage and after the bearing  
temperature has stabilized.  
5.5.3 Pump fitted with a mechanical seal  
A mechanical seal ensures a seal without leakage  
and does not need any adjustment. Nevertheless if a  
light leakage occurs during start-up, it should  
disappear after the initial running in of the friction  
faces.  
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  
5.6 Stopping and shutdown  
According to hydraulic conditions of  
the installation and its automation degree, stop and  
restart procedures can have different forms.  
Nevertheless all of them must respect imperatively  
the following rules:  
It is important, particularly with grease lubrication, to  
keep a check on bearing temperatures. After start up  
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.  
5.6.1 Stopping < 1 hour  
a) Isolate motor.  
5.5.5 Normal vibration levels, alarm and trip  
For guidance, pumps generally fall under a  
classification for rigid support machines within the  
International rotating machinery standards and the  
recommended maximum levels below are based on  
those standards.  
b) Avoid reverse rotation of the pump.  
c) Make sure that the discharge line pressure does  
not reach the foot valve.  
5.6.2 Stopping < 1 month  
a) Isolate motor.  
b) Avoid reverse rotation of the pump.  
c) Make sure that the discharge line pressure does  
not reach the foot valve.  
d) Close the outlet valve. Eventually close the inlet  
valve.  
Alarm and trip values for installed  
pumps should be based on the actual  
measurements (N) taken on site on the bearing  
housings of the pump in the fully commissioned as  
new condition.  
e) Switch off external power supply,  
flushing/quench, cooling liquid.  
The example (N) value is given for the preferred  
operating flow region (typically this may extend to 70  
to 120 % of the pump best efficiency point); outside  
the preferred flow region the actual vibration  
experienced may be multiplied by up to 2.  
5.6.3 Shutdown > 1 month  
a) Isolate motor.  
b) Avoid reverse rotation of the pump.  
c) Make sure that the discharge line pressure does  
not reach the foot valve.  
These standard values can vary with the rotational  
speed and the power absorbed by the pump. For  
any special case, do not hesitate to consult us.  
d) Close the outlet valve. Eventually close the inlet  
valve.  
e) Switch off external power supply,  
flushing/quench, cooling liquid.  
f) Keep the pump fully filled with water. In case of  
pumped liquid other than water, drain the pump  
entirely.  
Measuring vibration at regular intervals will then  
show any deterioration in pump or system operating  
conditions.  
g) Turn once per week the pump shaft of one or

FM USER INSTRUCTIONS ENGLISH 71576526 - 03/07  
If in doubt please consult your nearest Flowserve  
office for advice and details of the minimum  
allowable margin for your application.  
5.7 Hydraulic, mechanical and electrical  
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.  
5.7.5 Pumped flow  
Flow must not fall outside the minimum and  
maximum continuous safe flow shown on the pump  
performance curve and or data sheet.  
5.8 Pumps for Food Use or Potable  
Water  
5.7.1 Specific gravity (SG)  
Pump capacity and total head in meters (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.  
If the pump has not been specifically ordered for a food  
or drinking water application it must not be used for  
these types of applications. If it has been ordered for  
this type of application the following recommendations  
are to be followed.  
5.8.1 Cleaning prior to operation  
Pumps that are to be used for a food or drinking water  
application should be cleaned before being put into  
initial operation and after the installation of spare parts  
that are in contact with the liquid.  
5.7.2 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.  
Cleaning once the pump has been commissioned will  
depend on the application and operating conditions.  
The user must ensure that the cleaning procedures are  
suitable for the application and operating conditions,  
and local regulations.  
5.7.3 Pump speed  
Changing pump speed effects flow, total head,  
power absorbed, NPSHR, noise and vibration. Flow  
varies in 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, NPSHA > NPSHR, and  
that noise and vibration are within local requirements  
and regulations.  
6 MAINTENANCE  
6.1 General  
If a belt drive is used, the assembly and  
tension of the belts must be verified during regular  
maintenance procedure.  
In dirty or dusty environments, regular checks  
must be made and dirt removed from areas around  
close clearances, bearing housings and motors.  
5.7.4 Net positive suction head (NPSHA)  
NPSH available (NPSHA) is the head available at the  
impeller inlet, above the vapor pressure of the  
pumped liquid.  
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  
1.6.2).  
NPSH required (NPSHR) is the minimum head required  
at the impeller inlet, above the vapor pressure of the  
pumped liquid, to avoid excessive cavitation and  
extreme performance degradation.  
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 5.6.  
It is important that NPSHA > NPSHR. The margin  
between NPSHA > NPSHR should be as large as  
possible.  
On completion of work all guards and safety devices  
must be re-installed and made operative again.  
If any change in NPSHA is proposed, ensure these  
margins are not significantly eroded. Refer to the  
pump performance curve to determine exact  
requirements particularly if flow has changed.

FM USER INSTRUCTIONS ENGLISH 71576526 - 03/07  
Before restarting the machine, the relevant  
instructions listed in section 5, Commissioning, start  
up, operation and shut down must be observed.  
d) Verify the condition of the gaskets  
e) Gland packing must be adjusted correctly to give  
visible leakage and concentric alignment of the  
gland follower to prevent excessive temperature  
of the packing or follower. Mechanical seals  
should present no leakage.  
f) Check for any leaks from gaskets and seals.  
The correct functioning of the shaft seal must be  
checked regularly.  
Oil and grease leaks may make the ground  
slippery. Machine maintenance must always  
begin and finish by cleaning the ground and the  
exterior of the machine.  
If platforms, stairs and guardrails are required for  
maintenance, they must be placed for easy access  
to areas where maintenance and inspection are to  
be carried out. The positioning of these accessories  
must not limit access or hinder the lifting of the part  
to be serviced.  
g) Check bearing lubricant level, and if the hours  
run show a lubricant change is required.  
h) Check that the duty condition is in the safe  
operating range for the pump.  
i) Check vibration, noise level and surface  
temperature at the bearings to confirm  
satisfactory operation.  
When air or compressed inert gas are used to clean  
the machines, the operator and those people in the  
vicinity must be careful and have appropriate gas-  
protection, wearing at least eye protectors.  
j) Check the tightness of the connections,.  
k) Check dirt and dust is removed from areas  
around close clearances, bearing housings and  
motors.  
l) Check coupling alignment and re-align if  
Do not spray air or compressed inert gas on skin.  
Do not direct an air or gas jet towards other people.

m) Verify the correct operation of the system.  
The equipment used for maintenance and  
disassembly in an ATEX zone must be in conformity  
with the requirements zone.  
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:  
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.  
"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".  
If any problems are found the following sequence of  
actions should take place:  
a) Refer to section 7, Faults; causes and remedies,  
for fault diagnosis.  
b) Ensure equipment complies with the  
recommendations in this manual.

6.2.5 Gland packing  
6.2.2 Routine inspection (daily/weekly)  
6.2.5.1 Pump fitted with a packed gland  
A well run in and correctly adjusted packing gland  
requires little maintenance  
If, after some time, the leakage becomes too great,  
the gland should be tightened again in order to  
return these to a normal level.  
The following checks should be made  
and the appropriate action taken to remedy any  
deviations:  
a) Check the behavior of the pump while running:  
noise level, vibrations, bearings temperature,  
flow rate and pressure.  
b) Pump fitted with a stuffing box: leakage of 20  
drops per minute.  
If re-tightening is not possible, new packing must be  
installed.  
c) Pump fitted with a mechanical seal: no leakage.  
d) Check the level and condition of oil lubricant. On  
grease lubricated pumps, check running hours  
since last recharge of grease or complete  
grease change.  
6.2.5.2 Gland packing inspection and removal  
a) Remove the shield guards  
b) Slide back the gland  
c) Remove the packing rings with an extractor  
designed for this purpose (including the lantern  
ring if it exists; note its position and its direction  
of rotation).  
d) Inspect the state of the sleeve surface; the  
presence of many marked grooves will indicate  
that it must be replaced.  
6.2.3 Periodic inspection (6 monthly)  
Check pump running records for hourly usage to  
determine if bearing lubricant requires changing.  
If a check shows a bad running of the  
motor pump unit, the user must:  
e) Carefully clean the different pieces of the  
packing gland.  
a) Refer to the "fault finding chart" chapter 7 of this  
leaflet to apply the recommended solutions.  
b) Ensure that your equipment corresponds to the  
arrangements of this leaflet  
c) Contact Flowserve after-sales Department if the  
problem persists.  
6.2.5.3 Gland packing fitting  
If the packing is supplied as cord the packing must  
be cut so that the external diameter is lightly  
tightened and there is an initial gap between the  
sleeve and the packing ring.  
6.2.4 Mechanical seals  
For that purpose, wind the packing helically around  
the shaft sleeve or a chuck of the same diameter.  
(Take precautions to avoid damaging sleeve).  
The current maintenance is limited to seal control. It  
is necessary to detect any small leakage which  
announces the beginning of the deterioration of  
friction faces or secondary seal elements (rings,  
bellows, synthetic membranes). It is advisable to  
stop the pump as soon as possible. Have an  
approved seal vendor replace or repair the seal.  
Example of straight cut  
Example of bevel cut

Ensure a tightening on the stuffing  
box housing and not on the sleeve.  
SETTING OF PACKING  
Follow the instructions:  
a) Assembly of the packing in S.  
b) Staggering by about 90° between two pickings.  
c) Assemble packing after packing.

FM USER INSTRUCTIONS ENGLISH 71576526 - 03/07  
After setting the last packing, fix the gland on the  
packing and screw up the nut by hand.  
The pump size and serial number are shown on the  
pump nameplate.  
After this screwing phase, the shaft should turn by  
hand as easily as before the setting of the packing.  
To ensure continued satisfactory operation,  
replacement parts to the original design specification  
should be obtained from Flowserve.  
Any change to the original design specification  
(modification or use of a non-standard part) will  
invalidate the pumps safety certification.  
6.3.2 Storage of spares  
Spares should be stored in a clean dry area away  
from vibration. Inspection and re-treatment of  
metallic surfaces (if necessary) with preservative is  
recommended at 6 monthly intervals.

6.2.6 Internal coating  
Refer to section 1.6, Safety, and section 6  
If the pump has an internal coating, this coating  
must be inspected periodically. Any wear or cracks  
of the coating found must be immediately repaired.  
Failure to do this may lead to accelerated wear of  
the coating during operation and corrosion of the  
exposed base metal, depending on the material and  
pumped liquid. Special attention must be paid to the  
coating edges. Any loss of coating material is  
considered to be normal wear and tear on the pump  
and is not considered as warranty. Flowserve has  
applied the coatings according to the supplier's  
instructions but will not be held responsible for  
coating wear or cracks that may develop over time.  
Maintenance, before dismantling the pump.  
Before dismantling the pump for  
overhaul, ensure genuine Flowserve replacement  
parts are available. Refer to sectional drawings for  
part numbers and identification.
