FP USER INSTRUCTIONS ENGLISH 71576286 - 07/06  
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.  
This sign is not a safety symbol but indicates  
an important instruction in the assembly process.  
NEVER APPLY HEAT TO REMOVE  
IMPELLER  
Trapped lubricant or vapour could cause an  
explosion.  
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.

FP USER INSTRUCTIONS ENGLISH 71576286 - 07/06  
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.  
Measures are required to:  
Avoid excess temperature.  
Prevent build up of explosive mixtures.  
Prevent the generation of sparks.  
Prevent leakages.  
Gland packing must not be used when pumping  
hazardous liquids.  
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.  
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.  
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.  
ENSURE CORRECT LUBRICATION  
(See section 5, Commissioning, startup, operation  
and shutdown.)  
START THE PUMP WITH OUTLET  
VALVE PART OPENED  
(Unless otherwise instructed at a specific point in the  
User Instructions.)  
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.  
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.)  
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.  
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.  
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 cavitations. Low flow  
rates may cause a reduction in pump/bearing life,  
overheating of the pump, instability and  
cavitations/vibration.

FP USER INSTRUCTIONS ENGLISH 71576286 - 07/06  
The responsibility for compliance with the  
specified maximum liquid temperature is with the  
plant operator.  
1.6.4.2 Marking  
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 prEn13463-5)  
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.

FP USER INSTRUCTIONS ENGLISH 71576286 - 07/06  
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 Safety labels summary  
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.  
1.7.2 Warning labels  
The coupling must be selected to comply with  
94/9/EC and correct alignment must be maintained.  
Additional requirements for metallic pumps on  
non-metallic baseplates  
When metallic components are fitted on a non-  
metallic 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 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. Where there  
is a risk from such tools or materials; maintenance  
must be conducted in a safe area.

FP USER INSTRUCTIONS ENGLISH 71576286 - 07/06  
The values are based on the noisiest ungeared  
electric motors which are likely to be encountered.  
They are LpA sound pressure levels at 1m (3.3ft)  
from the directly driven pump, for "free field over a  
reflecting plane". For estimating LwA sound power  
level (re 1 pW) add 14 dB(A) to the sound pressure  
value.  
1.9 Noise level  
When pump noise level exceeds 85dBA attention  
must be given to prevailing Health and Safety  
Legislation, to limit the exposure of plant operating  
personnel to the noise. The usual approach is to  
control 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 machines above a  
certain power level will exceed 85 dB(A). In such  
situations consideration must be given to the fitting  
of an acoustic enclosure to meet local regulations.  
If a pump only has been purchased, for fitting with  
your own driver, then the "pump only" noise levels  
from the table should be combined with the level for  
the driver obtained from the supplier. If the motor is  
driven by an inverter, it may show an increase in  
noise level at some speeds. Consult a Noise  
Specialist for this calculation  
Pump noise level is dependent on a number of  
factors - the type of motor fitted, the operating  
capacity, pipework design and acoustic  
characteristics of the building. Typical sound  
pressure levels measured in dB and A-weighted are  
shown in the table below.  
For units driven by equipment other than  
electric motors or units contained within enclosures,  
see the accompanying information sheets and  
manuals.  
The figures are indicative only, they are subject to a  
+3 dB tolerance, and cannot be guaranteed.

must stay in the safety limits for the staff. 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.  
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.

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.  
NF E 27 811  
Provide sufficient space in the foundation to  
accommodate the anchor bolts. If necessary,  
provide concrete risers.  
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.  
Usually the pump and its drive are mounted on a  
common base plate. If not, individual base plates  
underneath each machine foot shall be installed.  
Base plates are to be fully grouted.  
4.2.1 Setting the base plate for anchoring  
a) Clean the foundation surface thoroughly.  
b) Put shims on the foundation surface (approx 20-  
25 mm thick), one on each side of the bolt hole  
(as an alternative, leveling screws can be used).  
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.  
c) Lay the base plate and level in both directions  
with extra shims. The base plate should be level  
to within 0.5 mm per 1 m.  
The base plate should be mounted onto a firm  
foundation, either an appropriate thickness of quality  
concrete or sturdy steel framework. It should NOT  
be distorted or pulled down onto the surface of the  
foundation, but should be supported to maintain the  
original alignment.  
Anchor bolts must be in accordance with the foot  
bolt holes. Use anchor bolts of accepted standards  
and sufficient to ensure seave fitting in the  
foundation. Particularly, this applies to individual  
plates where the anchor bolts have to withstand the  
driving torque.  
d) If anchor bolts have been pre-cast in the  
foundation slightly tighten the anchor bolts.  
Otherwise let them hang in the foundation holes.

4.4.1 Thermal expansion  
4.3 Grouting  
4.3.1 Base plate grouting  
The pump and motor will normally  
have to be aligned at ambient temperature and  
should be corrected to allow for thermal expansion  
at operating temperature. In pump installations  
involving high liquid temperatures, the unit should be  
run at the actual operating temperature, shut down  
and the alignment checked immediately.  
a) Prepare the site for grouting. Before grouting  
clean the foundation surface thoroughly and  
provide external barriers as shown:  
4.4.2 Alignment methods  
Ensure pump and driver are isolated  
electrically and the half couplings are disconnected.  
Ensure that the pump pipework, suction and  
discharge, is disconnected.  
Barriers  
The alignment MUST be checked.  
Although the pump will have been aligned at the  
factory it is most likely that this alignment will have  
been disturbed during transportation or handling. If  
necessary, align the motor to the pump, not the  
pump to the motor.  
b) Prepare grouting product (concrete, resin) in  
accordance with manufacturers' instructions.  
Alignment  
Parallelism and concentricity check:  
Check the alignment at three or four  
points, before pipeworks assembly.  
with a rule  
with a comparator  
Admissible margin for a motor with roller bearings:  
= 0.15 mm parallel checking  
= 0.1 mm angular checking  
c) Use grouting products with anti-shrinking  
components.  
d) To grout up to the required level. Polish  
surfaces. Take necessary precautions to avoid  
air bubbles.  
Angular checking:  
e) Lay-down the barrier, break external angles, and  
polish the different surfaces.  
f) After grout starts to cure, definitively tighten  
anchor bolts.  
g) Control the alignment such as described as  
follows.  
with a sliding rule  
with a caliper gauge  
4.4 Initial alignment  
The alignment will be definitive only  
after pipework connection (see § 4.5.1).  
Before connecting the couplings  
verify the motor rotation direction.

FP USER INSTRUCTIONS ENGLISH 71576286 - 07/06  
When designing the pipes (§ 4.5.2.1, § 4.5.2.2, §  
4.5.3.1) take necessary precautions in order not to  
exceed maximum allowed strains.  
If necessary, improve the machine alignment:  
Complete unit mounted on common base plate:  
The machines are first aligned accurately in our  
workshops. Usually, any misalignment observed on-  
site is due to a wrong adjustment under the base  
plate (disturbed during transport or because of  
forces exerted by the pipework). It is only necessary  
to rectify the adjustment under base plate. If it  
proves to be insufficient, modify the motor and the  
pipeworks adjustment.  
Forces and moments applied to the pump flanges  
must never exceed the values shown in the table

FP USER INSTRUCTIONS ENGLISH 71576286 - 07/06  
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.  
Avoid mechanical, hydraulic or electrical  
overload by using motor overload trips or a power  
monitor and make routine vibration monitoring.  
It is important to be aware of the EUROPEAN  
DIRECTIVE on electromagnetic compatibility when  
wiring up and installing equipment on site. Attention  
must be paid to ensure that the techniques used during  
wiring/installation do not increase electromagnetic  
emissions or decrease the electromagnetic immunity of  
the equipment, wiring or any connected devices. If in  
any doubt, contact Flowserve for advice.  
If leakage of product from the pump or its associated  
sealing system can cause a hazard it is  
recommended that an appropriate leakage detection  
system is installed.  
To prevent excessive surface temperatures at  
bearings it is recommended that temperature or  
vibration monitoring are carried out. See sections  
5.5.4 and 5.5.5.  
The motor must be wired up in  
accordance with the motor manufacturer's  
instructions (normally supplied within the terminal  
box) including any temperature, earth leakage,  
current and other protective devices as appropriate.  
If a defect of cooling can lead to temperature higher  
than those acceptable a system of cooling  
surveillance must be installed.  
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 identification nameplate should be checked to  
ensure the power supply is appropriate.  
A device to provide emergency stopping shall be  
fitted.  
The customer must install all equipment required to  
avoid water hammer.  
Carry out the ground connections according to the  
current local regulations.  
5 COMMISSIONING, START-UP,  
OPERATION AND SHUTDOWN  
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).  
These operations must be carried out by  
fully qualified personnel.  
4.7 Final shaft alignment check  
a) Check the alignment pump-motor according to  
the procedure § 4.4.2. Rectify if necessary by  
adjusting the motor only.  
b) Check by hand that the pump turns freely. A  
binding indicates a distortion of the pump, which  
is due to excessive pipes strains. If necessary  
the pipework design must be re-examined.  
c) If it provided, connect auxiliary pipe systems  
(hydraulic, pneumatic, sealing system).  
d) Control tightness and functionality of auxiliary  
piping.  
5.1 Direction of rotation  
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. 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.  
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.  
4.8 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

c) When the pump is totally free of air bubbles,  
replace the plugs.  
5.3 Priming and auxiliary supplies  
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.  
Air escape  
Air escape  
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.  
These operations must be carried out by personnel  
with approved qualifications.  
Priming of sump suction pump with foot valve  
5.3.1 Priming of a flooded pump  
a) As discharge valve is closed, fill the pump by  
opening the valve at suction.  
*Without foot valve:  
Priming may be accomplished by means of venting  
system.  
b) Let air escape by removing the plugs situated on  
the flange of the discharge casing and suction  
casing (for the 122, 152 to 202 FP pumps). For  
the 50 to 125 FP pumps, plugs are located on  
pipework.  
c) 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.  
Foot valves are not recommended when  
the pumped liquid has suspended solid particles.  
They may lodge between foot valve seat and  
shutter.  
5.4 Starting the pump  
d) When the pump is totally free of air bubbles,  
replace the plugs.  
5.4.1 Bring controls and preparation before the  
first starting and after each service call  
Necessarily:  
a) Check the tightening of the different plugs.  
b) Check that the gland lightly tightens the packing  
rings.

particularly the coupling guard and the shield  
grid (reference [9331]) of the bearing.  
Priming of a flooded pump  
5.3.2 Priming of a sump suction pump  
f) Open all suction valves (if existing).  
g) Close the outlet valve and the bypass valve.  
h) Ensure inlet pipe and pump casing are  
completely full of liquid.  
* With foot valve:  
a) Fill suction pipe and casing with liquid from an  
independent source (pressure 1 to 2 bars).  
b) Let air escape by removing the plugs situated on  
the flange of the discharge casing and suction  
casing (for the 122, 152 to 202 FP pumps). For  
the 50 to 125 FP pumps, plugs are located on  
pipes.  
5.4.2 First pump start-up  
Suction valves must be fully open  
when pump is running. Never run the pump dry, it  
will cause damage.

FP USER INSTRUCTIONS ENGLISH 71576286 - 07/06  
a) Start motor and check outlet pressure.  
b) If pressure is satisfactory, slowly OPEN outlet  
valve.  
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 faultfinding chart for fault  
diagnosis.  
The pump should run smoothly and without  
vibration.  
The pump must never run at a capacity of less than  
10 % of that at the best efficiency.  
Never remove a plug when the pump is  
running.  
5.5 Running the pump  
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.  
5.5.1 Venting the pump  
Vent the pump to enable all trapped air to  
escape taking due care with hot or hazardous  
liquids. Under normal operating conditions, after the  
pump has been fully primed and vented, it should be  
unnecessary to re-vent the pump.  
5.5.3 Pump fitted with 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.  
5.5.2 Pump fitted with a stuffing box  
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  
4240 4213  
2110  
2445  
4200  
4610  
stopped and allowed to cool before being restarted.  
When the pump is restarted 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.  
NEVER RUN A MECHANICAL SEAL  
DRY, EVEN FOR A SHORT WHILE.  
SAFETY INSTRUCTIONS WHEN THE PUMP IS  
RUNNING:  
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. 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. The leakage must not be reduced below a  
rate of 20 drops per minute. Bedding in of the  
packing may take several hours.  
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.  
If the temperature is greater than 80 °C, a  
warning plate must be clearly placed on the pump.

and 105 C (220 F) for grease lubrication  
Where duty and standby pumps are installed it is  
recommended that they are run alternately every  
week.  
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 Stopping and shutdown  
5.6.1 Stopping and restarting in continuous  
running  
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:  
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.  
Stopping:  
a) Avoid that the unit turns in the opposite direction  
to the normal running.  
b) Make sure that the discharge line pressure does  
not reach the foot 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.  
c) Avoid a continuous running below the authorized  
flow rate (see § 5.4.2).  
Restart:  
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.  
a) Ensure that the pump is completely full of liquid.  
b) Ensure a continuous supply with a sufficient  
available NPSH.  
c) Ensure a backpressure so that the motor power  
is not in excess.  
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.  
Measuring vibration at regular intervals will then  
show any deterioration in pump or system operating  
conditions.  
d)  
e)  
Respect the starting frequency  
imposed by the motor manufacturer.  
Protect the pump against water hammer  
when stopping or starting.  
Page 20 of 35  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
FP USER INSTRUCTIONS ENGLISH 71576286 - 07/06  
NPSH required (NPSHR) is the minimum head required  
at the impeller inlet, above the vapour pressure of the  
pumped liquid, to avoid excessive cavitation and  
extreme performance degradation.  
Shutdown:  
Close the outlet valve and stop the  
motor. Eventually close the inlet valve.  
It is important that NPSHA > NPSHR. The margin  
between NPSHA > NPSHR should be as large as  
possible.  
For prolonged shutdowns and  
especially when ambient temperatures are likely to  
drop below freezing point, the pump and any cooling  
and flushing arrangements must be drained or  
otherwise protected.  
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.  
5.7 Hydraulic, mechanical and electrical  
duty  
If in doubt please consult your nearest Flowserve  
office for advice and details of the minimum  
allowable margin for your application.  
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.  
5.7.1 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.  
5.8 Pumps for Food Use or Potable  
Water  
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.  
5.7.2 Viscosity  
5.8.1 Cleaning prior to operation  
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.  
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.  
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 vapour pressure of the  
pumped liquid.

FP USER INSTRUCTIONS ENGLISH 71576286 - 07/06  
a) The pump must be completely vented and  
drained and rendered inert before any  
disassembly operation.  
b) Any auxiliary systems installed must be  
monitored, if necessary, to ensure they function  
correctly.  
c) During cleaning of the pump ensure the  
compatibility between the cleaning products and  
the gaskets.  
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).  
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.  
d) Verify the condition of the gaskets.  
e) Gland packings must be adjusted correctly to  
give visible leakage and concentric alignment of  
the gland follower to prevent excessive  
temperature of the packing or follower.  
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.  
On completion of work all guards and safety devices  
must be re-installed and made operative again.  
Before restarting the machine, the relevant  
instructions listed in section 5, Commissioning, start  
up, operation and shut down must be observed.  
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.  
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.  
j) Check the tightness of the connections.  
k) Check dirt and dust is removed from areas  
around close clearances, bearing housings and  
motors.  
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.  
l) Check coupling alignment and re-align if  
necessary.  
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.  
When air or compressed inert gas is used in  
the maintenance process, the operator and anyone  
in the vicinity must be careful and have the  
appropriate protection. DO NOT SPRAY air or  
compressed inert gas on skin. DO NOT DIRECT an  
air or gas jet towards other people. Never use air or  
compressed inert gas to clean clothes.  
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.  
Before working on the pump, take measures to  
prevent an uncontrolled start. Put a warning board  
on the starting device with the words:  
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.  
c) Contact Flowserve if the problem persists.  
"Machine under repair: do not start".  
With electric drive equipment, lock the main switch  
open and withdraw any fuses. Put a warning board  
on the fuse box or main switch with the words:  
"Machine under repair: do not connect".  
Never clean equipment with inflammable solvents or  
carbon tetrachloride. Protect yourself against toxic  
fumes when using cleaning agents.  
6.2.1 Standard maintenance  
Roller bearing  
6.2 Maintenance schedule  
The bearings fitted are prepacked with grease at the  
factory. When the regreasing period is reached it is  
necessary to remove as much of the old grease as  
possible with a clean lint free cloth and repack the  
bearings with fresh grease.  
It is recommended that a maintenance plan  
and schedule is adopted, in line with these User  
Instructions. It should include the following:

SHELL ALVANIA R2  
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.  
Its equivalents: MOBIL : Mobilux EP 2,  
TOTAL : Multis 2,  
ELF  
6.2.2 Routine inspection (daily/weekly)  
The following checks should be made  
: ELF MULTI  
If re-tightening is not possible, new packing must be  
installed  
and the appropriate action taken to remedy any  
deviations:  
6.2.5.2 Gland packing inspection and removal  
a) Remove the shield guards.  
a) Check operating behavior. Ensure noise,  
vibration and bearing temperatures are normal.  
b) Check that there are no abnormal fluid or  
lubricant leaks (static and dynamic seals) and  
that any sealant systems (if fitted) are full and  
operating normally.  
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.  
c) Pump fitted with a stuffing box: leakage of 20  
drops per minute.  
d) Pump fitted with a mechanical seal: no leakage.  
e) Check the level and condition of oil lubricant. On  
grease lubricated pumps, check running hours  
since last recharge of grease or complete  
grease change.  
e) Carefully clean the different pieces of the  
packing gland.  
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.  
6.2.3 Periodic inspection (six monthly)  
a)  
Check foundation bolts for  
security of attachment and corrosion.  
For that purpose, wind the packing helically around  
the shaft sleeve or a chuck of the same diameter.  
(Take precautions to avoid damaging sleeve)  
b) Check pump-running records for hourly usage to  
determine if bearing lubricant requires changing.  
c) The coupling should be checked for correct  
alignment and worn driving elements.

SETTING OF PACKING  
Follow the instructions:  
109 150 M16  
a) Assemble of the packing in S.  
b) Stagger by about 90° between two rings.  
c) Assemble packing after packing.  
For arrangement of packing, see section 8.1,  
Sectional drawings.  
6.2.6 Internal coating  
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.  
After setting the last packing ring, secure the  
packing with the gland and tighten the nut by hand.  
After tightening, the shaft should turn by hand as  
easily as before the setting of the packing.  
6.3 Spare parts  
6.3.1 Ordering of spares  
Flowserve keeps records of all pumps that have  
been supplied. When ordering spares the following  
information should be quoted:  
1) Pump serial number.  
2) Pump size.  
3) Part name  
4) Part number  
5) Number of parts required.  
The pump size and serial number are shown on the  
pump nameplate.  
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 pump’s  
safety certification.
