and instruction must be provided. If required the

operator may commission the manufacturer/supplier
to provide applicable training.

Always coordinate repair activity with operations and
health and safety personnel, and follow all plant

safety requirements and applicable safety and health
laws and regulations.

1.6.3 Safety action

This is a summary of conditions and actions to
prevent injury to personnel and damage to the

environment and to equipment. For products
used in potentially explosive atmospheres

section 1.6.4 also applies.

NEVER DO MAINTENANCE WORK

WHEN THE UNIT IS CONNECTED TO POWER

GUARDS MUST NOT BE REMOVED WHILE

THE PUMP IS OPERATIONAL

DRAIN THE PUMP AND ISOLATE
PIPEWORK BEFORE DISMANTLING THE PUMP
The appropriate safety precautions should be taken

where the pumped liquids are hazardous.

FLUORO-ELASTOMERS (When fitted.)
When a pump has experienced temperatures over

250 ºC (482 ºF), partial decomposition of fluoro­elastomers (example: Viton) will occur. In this

condition these are extremely dangerous and skin
contact must be avoided.

HANDLING COMPONENTS
Many precision parts have sharp corners and the

wearing of appropriate safety gloves and equipment
is required when handling these components. To lift

heavy pieces above 25 kg (55 lb) use a crane
appropriate for the mass and in accordance with

current local regulations.

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 APPLYHEAT TO REMOVE
IMPELLER

Trapped lubricantor vapour could cause an
explosion.

HOT (and cold) PARTS
If hot or freezing components or auxiliary heating

supplies can present a danger to operators and
persons entering the immediate area action must be

taken to avoid accidental contact. If complete
protection is not possible, the machine access must

be limited to maintenance staff only, with clear visual
warnings and indicators to those entering the

immediate area. Note: bearing housings must not be
insulated and drive motors and bearings may be hot.

If the temperature is greater than 68 °C (175 °F)
or below 5 °C (20 °F) in a restricted zone, or

exceeds local regulations, action as above shall
be taken.

HAZARDOUS LIQUIDS

Whenthe pumpishandling hazardousliquids care
mustbetakentoavoidexposure to the liquid by

appropriatesittingof the pump,limiting personnel
access andbyoperator training.If the liquid is

flammable and/or explosive, strict safetyprocedures
mustbeapplied.

Gland packing must not be used when pumping
hazardous liquids.

PREVENT EXCESSIVE EXTERNAL

PIPE LOAD
Do not use pump as a support for piping. Do not

mount expansion joints, unless allowed by
Flowserve in writing, so that their force, due to

internal pressure, acts on the pump flange.

ENSURE CORRECT LUBRICATION

(See section 5, Commissioning, startup, operation
and shutdown.)

START THE PUMP WITH OUTLET

VALVE PART OPENED
(Unless otherwise instructed at a specific point in the

User Instructions.)
This is recommended to minimize the risk of

overloading and damaging the pump motor at full or
zero flow. Pumps may be started with the valve

further open only on installations where this situation
cannot occur. 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.)

NEVER RUN THE PUMP DRY

1.6.4 Products used in potentially explosive
atmospheres

Measures are required to:

 Avoid excess temperature.
 Prevent build up of explosive mixtures.
 Prevent the generation of sparks.
 Prevent leakages.

 Maintain the pump to avoid hazard.

Thefollowing instructions for pumpsand pumpunits

Maximum surfacetemperature (Temperature Class)
(see section 1.6.4.3)

1.6.4.3 Avoiding excessive surface temperatures

ENSURE THE EQUIPMENT TEMPERATURE

CLASS IS SUITABLE FOR THE HAZARD ZONE
Pumps have a temperature class as stated in the

ATEX Ex rating on the nameplate. These are based
on a maximum ambient of 40 °C (104 °F); refer to

Flowserve for higher ambient temperatures.

The responsibility for compliance with the
specified maximum liquid temperature is with the

plant operator.

Temperature classification “Tx” is used when the
liquid temperature varies and 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.

If an explosive atmosphere exists during the
installation, do not attempt to check the direction of

rotation by starting the pump unfilled. Even a short
run time may give a high temperature resulting from

contact between rotating and stationary
components. 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.
Where there is any risk of the pump being run against

a closed valve generating high liquid and casing
externalsurface temperaturesit is recommended that

users fit an external surface temperature protection
device.

Avoid mechanical, hydraulic or electrical overload by
using motor overload trips, temperature monitor or a

power monitor and make routine vibration monitoring
checks.

In dirty or dusty environments, regular checks must
be made and dirt removed from areas around close

clearances, bearing housings and motors.

1.6.4.4 Preventing the build up of explosive
mixtures

The surface temperature on the pump is influenced
by the temperature of the liquid handled. The

maximum permissible liquid temperature depends
on the temperature class and must not exceed the

values in the table that follows.
The temperature rise at the seals, bearings and due

to the minimum permitted flow rate is taken into
account in the temperatures stated.

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.

If the operation of the system cannot avoid this
condition the fitting of an appropriate dry run

protection device is recommended (eg liquid
detection or power monitor).

To avoid potential hazards from fugitive emissions of
vapour or gas to atmosphere the surrounding area

must be well ventilated.

FP USER INSTRUCTIONS ENGLISH 71576286 - 07/06

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.

Avoid electrostatic charge: do not rub non-

metallic surfaces with a dry cloth, ensure cloth is
damp.

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 non­metallic baseplate they must be individually earthed.

1.6.4.6 Preventing leakage

The pump must only be used to handle liquids

for which it has been approved to have the correct
corrosion resistance.

It is recommended that a maintenance plan and
schedule is adopted. (See section 6, Maintenance.)

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.

1.7.2 Warning labels

Avoid entrapment of liquid in the pumpand associated
piping duetoclosingof suction anddischarge valves,

which couldcause dangerous excessive pressures to
occur if there is heat input to theliquid.This canoccur

ifthepump is stationary or running.
Bursting of liquid containing parts due to freezing

must be avoided by draining or protecting the pump
and ancillary systems.

Where there is the potential hazard of a loss of a
seal barrier fluid or external flush, the fluid must be

monitored.
If leakage of liquid to atmosphere can result in a

hazard, the installation of a liquid detection device is
recommended.

1.6.4.7 Maintenance to avoid the hazard

CORRECT MAINTENANCE IS REQUIRED

TO AVOID POTENTIAL HAZARDS WHICH GIVE A
RISK OF EXPLOSION

Theresponsibilityforcompliancewith
maintenance instructions is withtheplant
operator.

Oil lubricated units only:

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.

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.

Page 8 of 35

FP USER INSTRUCTIONS ENGLISH 71576286 - 07/06

1.9 Noise level

When pump noise level exceeds 85dBAattention
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 meetlocal regulations.

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.

The figures are indicative only, they are subject to a
+3 dB tolerance, and cannot be guaranteed.

The values are based on the noisiest ungeared
electric motors which are likely to be encountered.

They are LpAsound pressure levels at 1m (3.3ft)
from the directly driven pump, for "free field over a

reflecting plane". For estimating LwAsound power
level (re 1 pW) add 14 dB(A) to the sound pressure

value.
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

 For units driven by equipment other than

electric motors or units contained within enclosures,
see the accompanying information sheets and

manuals.

In areas where the staff has to intervene, remember
that when the level of the sound pressure is:

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.

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.

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.

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.

Any shortage and or damage must be reported
immediately to Flowserve Pump Division and

received in writing within one month of receipt of the
equipment. Later claims cannot be accepted.

Check any crate, boxes and wrappings for any
accessories or spare parts that may be packed

separately with the equipment or attached to
sidewalls of the box or equipment.

Each product has a unique serial number. Check
that this number corresponds with that advised and

always quote this number in correspondence as well
as when ordering spare parts or further accessories.

2.2 Handling

2.2.1 General instructions concerning handling

Boxes, crates, pallets or cartons may be unloaded
using forklift vehicles or slings dependent on their

size and construction. See 2.3.1 for positioning of
slings.

To lift heavy pieces above 25 kg (55 lb), use a winch
adapted to the mass and in accordance with the

current local regulations.
To lift machines or pieces with one or several

suspension rings, only use hooks and chains in
compliance with the local regulations concerning

safety. 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.

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.
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. 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.

3 PUMP DESCRIPTION

3.1 Configurations

The multi-stagecentrifugal pump is designed for the
pumping of cold water or all clear liquids which are

not solid and liquid mixtures, non-corrosive, non­abrasive 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 FP type pump is a centrifugal, multi-stage,

single suction and radial joint plan pump.
The modular design (2 hydraulics by pump type,

number of stages variation) enables an accurate
pump adjustment to the required operating

conditions.
It can be driven by electric motor, steam turbine, or

petrol or diesel motor.

For masses above 25 kg (55lb), manual

handling is forbidden.

The pump must be stored in a non-explosive,

ventilated location, sheltered from bad weather, dust
and vibrations.

4 INSTALLATION

NF E 27 811

Equipment operated in hazardous locations

must complywith the relevant explosion protection
regulations. See section 1.6.4, Products used in

potentially explosive atmospheres.

All equipment must be grounded.

FP USER INSTRUCTIONS ENGLISH 71576286 - 07/06

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.

4.2 Foundation

Provide sufficient space in the foundation to
accommodate the anchor bolts. If necessary,

provide concrete risers.
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).

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.

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
boltholes. 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.

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.

d) If anchor bolts have been pre-cast in the

foundation slightly tighten the anchor bolts.
Otherwise let them hang in the foundation holes.

FP USER INSTRUCTIONS ENGLISH 71576286 - 07/06

4.3 Grouting

4.3.1 Base plate grouting

a) Prepare the site for grouting. Before grouting

clean the foundation surface thoroughly and
provide external barriers as shown:

Barriers

b) Prepare grouting product (concrete, resin) in

accordance with manufacturers' instructions.

4.4.1 Thermal expansion

The pump and motor will normally

have to be aligned at ambient temperature and
should be corrected to allow for thermal expansion

at operating temperature. In pump installations
involving high liquid temperatures, the unit should be

run at the actual operating temperature, shut down
and the alignment checked immediately.

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.

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.

c) Use grouting products with anti-shrinking

components.

d) Togrout up to the required level. Polish

surfaces. Take necessary precautions to avoid
air bubbles.

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.

4.4 Initial alignment

Alignment
Parallelism and concentricity check:

Check the alignment at three or four

points, before pipeworks assembly.

with arule with acomparator

Admissible margin for a motor with roller bearings:
= 0.15 mm parallel checking
= 0.1 mm angular checking

Angular checking:

with a sliding rule with a caliper gauge

Before connecting the couplings

verify the motor rotation direction.

The alignment will be definitive only

after pipework connection (see § 4.5.1).

Page 14 of 35

FP USER INSTRUCTIONS ENGLISH 71576286 - 07/06

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.



Pump and motor mounted on individual base

plates:

Machines are (or must be) first mounted on their
own base plate in the workshop. Once the pump is

set, it will be regarded as the fixed piece. Any
alignment necessary shall be carried out on the

motor.

Never connect the electric motor

before the setting has been completely finished.

4.5 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.

4.5.1 Suction and discharge pipework

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 at suction,

and about 3 m/s at discharge.

b) Take into account the available NPSH, which

must be superior to the required NPSH of the
pump.

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.

Forces and moments applied to the pump flanges
must never exceed the values shown in the table

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, hot

bearings, worn couplings, vibrations and the
possible failure of the pump casing.

Page 15 of 35

Ensure piping and fittings are flushed

before use.

Ensure piping for hazardous liquids is

arranged to allow pump flushing before removal of
the pump.

The suction line must be as short and direct as
possible, never mount an elbow directly on the inlet

flange of the pump.

Valve

Non-return valve

Continous flow

Flooded suction configuration

a) Avoid sharp elbows or sudden narrowing. Use

convergent 20° (total angle).

b) Arrange thepipework so that there are no air

pockets (no bulges).

c) If high points cannot be avoided in suction line,

provide them with air relief cocks.

d) If a strainer is necessary, its net area should be

three or four times the area of the suction pipe.

e) If an inlet valve is necessary, choose a model

with direct crossing.

c) If a foot valve is necessary, do not oversize it

because it would generate pulsations (valve
beating).

Do not tighten flanges before the final

check (see § 4.5.4).

4.5.3 Discharge piping

4.5.3.1 Design of a discharge line

a) If discharge line is provided with a divergent, its

total angle will be between 7° and 12°.

b) Install the discharge valve after the non-return

valve downstream.

c) The non-return valve will be set in the discharge

pipe to protect the pump from any excessive
pressure surge and from reverse rotation.

If necessary, a control manometer can be connected
on the pipework.

c) Check that holes of pipework flanges are parallel

and correspond to those of the pump.

d) Tighten suction and discharge flanges.

4.6 Electrical connections

Electrical connections must be made

by a qualified Electrician in accordance with relevant
local national and international regulations. This

includes any grounding.

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.

Page 16 of 35

FP USER INSTRUCTIONS ENGLISH 71576286 - 07/06

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

DIRECTIVEon electromagneticcompatibilitywhen
wiring up andinstallingequipmentonsite.Attention

mustbepaidtoensurethat the techniques usedduring
wiring/installationdonot increaseelectromagnetic

emissions or decreasetheelectromagnetic immunityof
theequipment,wiringoranyconnecteddevices. If in

anydoubt,contact Flowserve for advice.

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 there are any circumstances in which the system
can allow the pump to run dry, or start up empty, a

power monitor should be fitted to stop the pump or
prevent it from being started. This is particularly

relevant if the pump is handling a flammable liquid.
If leakage of product from the pump or its associated

sealing system can cause a hazard it is
recommended that an appropriate leakage detection

system is installed.
To prevent excessive surface temperatures at

bearings it is recommended that temperature or
vibration monitoring are carried out. See sections

5.5.4 and 5.5.5.
If a defect of cooling can lead to temperature higher

than those acceptable a system of cooling
surveillance must be installed.

The identification nameplate should be checked to
ensure the power supply is appropriate.

A device to provide emergency stopping shall be
fitted.

Carry out the ground connections according to the
current local regulations.

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).

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.

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.

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.

5 COMMISSIONING, START-UP,
OPERATION AND SHUTDOWN

These operations must be carried out by

fully qualified personnel.

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.

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.

Page 17 of 35

FP USER INSTRUCTIONS ENGLISH 71576286 - 07/06

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.

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.

5.3.1 Priming of a flooded pump

a) As discharge valve is closed, fill the pump by

opening the valve at suction.

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.

d) When the pump is totally free of air bubbles,

replace the plugs.

c) When the pump is totally free of air bubbles,

replace the plugs.

Priming of a flooded pump

5.3.2 Priming of a sump suction pump

* 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.

Necessarily:

a) Check the tightening of the different plugs.
b) Check that the gland lightly tightens the packing

rings.

c) Risk of seal ring overheating.
d) Check the direction of rotation of the motor.

Refer to the rotation arrow of the pump.

e) Install all protection systems and more

particularly the coupling guard and the shield
grid (reference [9331]) of the bearing.

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.

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.

Page 18 of 35

a) Start motor and check outlet pressure.

2445

2110

4200

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

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.

5.5.2Pump 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

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.

FP USER INSTRUCTIONS ENGLISH 71576286 - 07/06

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.

5.5.3 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.

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.

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.

Page 19 of 35

NEVER RUN A MECHANICAL SEAL

DRY, EVEN FOR A SHORT WHILE.

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.

If the temperature is greater than 80 °C, a

warning plate must be clearly placed on the pump.

FP USER INSTRUCTIONS ENGLISH 71576286 - 07/06

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

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.
 Record the bearing temperature (t) and the

ambient temperature (ta)

 Estimate the likely maximum ambient

temperature (tb)

 Set the alarm at (t+tb-ta+5) C [(t+tb-ta+10) F]

and the trip at 100 C (212 F) for oil lubrication
and 105 C (220 F) for grease lubrication

It is important, particularly with grease lubrication, to
keep a 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.

5.5.5 Normal vibration levels, alarm and trip

For guidance, pumps generally fall under a
classification for rigid support machines within the
International rotating machinerystandards and the
recommended maximum levels below are based on
those standards.

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.

Vibration Velocity - unfiltered

Normal N 5.6 (0.22)

Alarm N x 1.25 7.1 (0.28)

Shutdown Trip N x 2.0 11.2 (0.44)

Horizontal Configuration

5.5.6 Stop/start frequency

Pump sets are normally suitable for the number of
equally spaced stop/starts per hour shown in the

table below. Check actual capability of the driver and
control/starting system before commissioning.

Where duty and standby pumps are installed it is
recommended that they are run alternately every

week.

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:
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.

c) Avoid a continuous running below the authorized

flow rate (see § 5.4.2).

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.
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.

Page 20 of 35

Restart:
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.

d) Respect the starting frequency

imposed by the motor manufacturer.

e) Protect the pump against water hammer

when stopping or starting.

FP USER INSTRUCTIONS ENGLISH 71576286 - 07/06

Shutdown:

Close the outlet valve and stop the

motor. Eventually close the inlet valve.

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.

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.

5.7.1 Specific gravity (SG)

Pumpcapacity 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.

NPSHrequired(NPSHR) is the minimum head required
at theimpeller inlet, above the vapour pressureofthe

pumped liquid,toavoid excessivecavitationand
extremeperformancedegradation.

It is important thatNPSHA> NPSHR. Themargin
betweenNPSHA> NPSHRshould be as large as

possible.
If any change in NPSHAis proposed, ensure these

margins are not significantly eroded. Refer to the
pump performance curve to determine exact

requirements particularly if flow has changed.
If in doubt please consult your nearest Flowserve

office for advice and details of the minimum
allowable margin for your application.

5.7.5 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

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

For a given flow rate the total head reduces with
increased viscosity and increases with reduced

viscosity. Also for a given flow rate the power
absorbed increases with increased viscosity, and

reduces with reduced viscosity. It is important that
checks are made with your nearest Flowserve office

if changes in viscosity are planned.

5.7.3 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
bedependent 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.

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.

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.

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.

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.

Page 21 of 35

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.
On completion of work all guards and safety devices

must be re-installed and made operative again.
Before restartingthe machine, the relevant

instructions listed in section 5, Commissioning, start
up, operation and shut downmust be observed.

Oil and grease leaks may make the ground
slippery. Machine maintenance must always

begin and finish by cleaning the ground and the
exterior of the machine.

If platforms, stairs and 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.

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.

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.

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.

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

necessary.

m) Verify the correct operation of the system.

When air or compressed inert gas is used in
the maintenanceprocess, the operator and anyone

in the vicinity must be careful and have the
appropriate protection. DO NOT SPRAY air or

compressed inert gas on skin. DO NOT DIRECT an
air or gas jet towards other people. Never use air or
compressed inert gas to clean clothes.

Before working on the pump, take measures to
prevent an uncontrolled start. Put a warning board

on the starting device with the words:
"Machine under repair: do not start".
With electric drive equipment, lock the main switch

open and withdraw any fuses. Put a warning board
on the fuse box or main switch with the words:

"Machine under repair: do not connect".

Never clean equipment with inflammable solvents or
carbon tetrachloride.Protect yourself against toxic
fumes when using cleaning agents.

6.2 Maintenance schedule

It is recommended that a maintenance plan

and schedule is adopted, in line with these User
Instructions. It should include the following:

The equipment used for maintenance and
disassembly in an ATEX zone must be in conformity

with the requirements zone.
Our specialist service personnel can help with

preventative maintenance records and provide
condition monitoring for temperature and vibration to

identify the onset of potential problems.
If any problems are found the following sequence of

actions should take place:
a) Refer to section 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.

6.2.1 Standard maintenance

Roller bearing

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.

6.2.2Routine inspection (daily/weekly)

The following checks should be made
and the appropriate action taken to remedy any
deviations:

a) Check operating behavior.Ensure noise,

vibration and bearing temperatures are normal.

b) Check that there are no abnormal fluid or

lubricant leaks (static and dynamic seals) and
that any sealant systems (if fitted) are full and
operating normally.

c) Pumpfitted 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.

6.2.3Periodic inspection (six monthly)

a) Check foundation bolts for

security of attachment and corrosion.

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.

If a check shows a bad running of the

motor pump unit, the user must:

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.

6.2.4 Mechanical seals

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.

6.2.5 Gland packing

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.

If re-tightening is not possible, new packing must be
installed

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.

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.

For that purpose, wind the packing helically around
the shaft sleeve or a chuck of the same diameter.

(Take precautions to avoid damaging sleeve)

Page 23 of 35

FP USER INSTRUCTIONS ENGLISH 71576286 - 07/06

Example of straight Example of bevel cut

Ensure a tightening on the stuffing

box housing and not on the sleeve.

SETTING OF PACKING

Follow the instructions:
a) Assemble of the packing in S.

b) Stagger by about 90° between two rings.
c) Assemble packing after packing.

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.

6.2.6 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.

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:

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
