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.

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 PUMPAND 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 fluoro-

elastomers (example: Viton) will occur. In this
condition these are extremely dangerous and skin

contact must be avoided.

HANDLING COMPONENTS
Many precision parts havesharp 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 andin accordance with
current local regulations.

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.

Thissignis nota safetysymbol butindicates

an importantinstruction intheassembly process.

1.6.2 Personnel qualification and training

All personnel involved in the operation, installation,
inspection and maintenance of the unit must be

qualified to carry out the work involved. If the
personnel in question do not already possess the

necessary knowledge and skill, appropriate training
and instruction must be provided. If required the

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

Always coordinate repair activity with operations and
health and safety personnel, andfollow allplant

safety requirements and applicable safety and health
laws and regulations.

THERMAL SHOCK
Rapid changes in the temperature of the liquid within

the pumpcan cause thermal shock, which can result
in damage or breakage of components and should

be avoided.

NEVERAPPLY HEATTO REMOVE
IMPELLER

Trapped lubricantor vapor could cause anexplosion.

HOT (and cold) PARTS
If hot or freezing components or auxiliary heating
supplies can present adanger to operators and

persons enteringthe 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 anddrive 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.

must be applied.

Gland packingmust not be used when pumping
hazardous liquids.

PREVENTEXCESSIVE 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 pumpflange.

FM USER INSTRUCTIONS ENGLISH 71576526 - 03/07

1.6.4 Productsused in potentially explosive
atmospheres

The following instructions for pumps andpump

units when installed in potentially explosive
atmospheres must be followedtohelpensure

explosion protection.
The terminology andprocedures ensure that the

installed pump is in compliance with the European
Directive 94/9/EC, knownas the ATEX Directive, which

is mandatory in Europe andmayalso bespecified in
other countries.Where applicable, bothelectricaland

non-electrical equipment must meet the requirements
94/9/EC.

Evenif theinstallationis in a region where ATEXis not
theapplicableregulation, the generalmeasures

described shall be followedto ensure safeoperation.

ENSURE CORRECTLUBRICATION

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

START THE PUMP WITHOUTLET

VALVE PARTOPENED
(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 thevalve

further open only on installations wherethis situation
cannot occur. Pump outlet valve shallmay need to

be adjusted to comply with the duty followingthe
run-up process. (See section 5, Commissioning

start-up, operation and shutdown.)

NEVER RUN THE PUMP DRY

INLET VALVES TO BE FULLY OPEN

WHEN PUMP IS RUNNING
Runningthe pump at zero flow or below the

recommended minimumflow continuously will cause
damage to the seal.

DO NOT RUN THE PUMPAT

ABNORMALLY HIGH OR LOW FLOW RATES
Operating at a flow rate higher than normalor at a
flow rate with no backpressure on the pump may

overload the motor and cause cavitation. Low flow
rates may cause a reduction in pump/bearing life,

overheating of the pump, instability and
cavitation/vibration.

The measures are explained under the headings of:

 Avoiding excessive surface temperature
 Preventing build up of explosive mixtures
 Preventing the generation of sparks
 Preventing leakages

 Maintaining the pump to avoid hazard

1.6.4.1 Scope of compliance

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 maximumambient 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 andthe pump could be

installed in different hazardous atmospheres. In this
case the user is responsible for ensuringthat 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 hightemperature resultingfrom

contact between rotating and stationary
components. Furthermore, confinement of liquid in

the pumpand pipes must be avoided (valveclosed).
If the liquid heats up this may cause excessive

pressure andlead to bursting of pumpcomponents.
Wherethereis anyrisk of the pumpbeing run against

a closed valve generatinghigh liquid and casing
externalsurface temperatures it is recommended that

users fit anexternal 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 aroundclose

clearances, bearing housings and motors.

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 fittingof an appropriate dry run

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

To avoid potential hazards fromfugitive emissions of
vapor or gas to atmosphere the surrounding area

must be well ventilated.

FM USER INSTRUCTIONS ENGLISH 71576526 - 03/07

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 groundcontact on the
baseplate must be used.

Avoid electrostatic charge: do not rubnon­metallic surfaces with a dry cloth, ensurecloth is
damp.

Where applicable 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

(grounded).

1.6.4.6 Preventing leakage

The pump must only be used to handle liquids
for which it has been approved to have the correct
corrosion resistance.

Where there is a risk fromsuch tools or materials;
maintenance must be conducted in a safe area.

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

1.7 Nameplate and safety labels

1.7.1 Nameplate

For details of nameplate, see the Declaration of
Conformity, or separate documentation included with

these User Instructions.

1.7.2 Safety labels

Avoidentrapmentof liquidin the pump andassociated
pipingdue to closingofsuction and dischargevalves,

which couldcause dangerous excessive pressures to
occurif there is heatinput to theliquid. Thiscanoccur

if the pump isstationaryor running.
Bursting of liquid containing parts due to freezing

must be avoided by draining or protectingthe 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

CORRECTMAINTENANCE IS REQUIRED
TO AVOID POTENTIAL HAZARDS WHICH GIVE A

RISK OF EXPLOSION

The responsibility forcompliance with
maintenance instructions is with the plant
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, cleaningand painting

materials used must not give rise to sparking or
adversely affect theambient conditions.

FM USER INSTRUCTIONS ENGLISH 71576526 - 03/07

1.9 Noise level

Attention must be given to the exposure of personnel
to the noise, and local legislation will define when

guidance to personnel on noise limitation is required,
and when noise exposure reduction is mandatory.

This is typically 80 to 85 dBA.
The usual approach is to control the exposure time

to the noise or to enclose the machine to reduce
emitted sound.

You may have already specified a limiting noise level
when the equipment was ordered, however if no

noise requirements were defined, then attention is
drawn to the following table to give an indication of

equipment noise level so that you can take the
appropriate action in your plant.

Pump noise level is dependent on a number of
operational factors, flow rate, pipework design and

acoustic characteristics of the building, and so the
values given are subject to a 3 dBA tolerance and

cannot be guaranteed.

Similarly the motor noise assumed in the “pump and
motor” noise is that typically expected from standard

and high efficiency motors when on load directly
driving the pump. Note that a motor driven byan

inverter may show an increased noise at some
speeds.

If a pump unit only has been purchased for fitting
with your own driver then the “pump only” noise

levels in the table should be combined with the level
for the driver obtained from the supplier. Consult

Flowserve or a noise specialist if assistance is
required in combining the values.

It is recommended that where exposureapproaches
the prescribed limit, thensite noise measurements

should be made.
The values are in sound pressure level LpAat 1 m

(3.3 ft) fromthe machine, for “free field conditions
over a reflecting plane”.

For estimating sound power level LWA (re 1 pW)
then add 17 dBA to the soundpressure value.

 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 stayingin 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 cominginto the room, even

for a short period, thatthey must wear hearing
protection.

 above 105 dBA: special hearing protection

adapted to this noise level and to the spectral
noise components must be installedand a

warning signto this effect erected at each entry.
The staff in the roommust wear ear protection.

Make sure thatthe noise, which travels through the
walls andwindows, does not generate too high

noise levels in the machine room's surroundings.

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 bendthe 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 whenthe
direction of the lifting force direction makes an angle

with the device axis.
To increase the safety andthe efficiency of the lifting

device, allthe lifting elements must be as
perpendicular as possible. If necessary a lifting

beam can be placed between the winchand 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 toswing or fall away.

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 the Flowserve andreceived in writing

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

Check any crates, boxes andwrappings for any
accessories or spare parts which may be packed

separately with the equipment or attached to side
walls of the box or equipment.

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

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

2.2 Handling

2.2.1 General instructions concerning handling

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

size andconstruction. See 2.3.1 for positioning of
slings.

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

current local regulations.

Never leave a load hanging froma winch. The
acceleration or the slowing-down of liftingequipment

must stay in thesafety limits for the staff.
A winch must be positionedin 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.

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.

4.1 Location

The pump shouldbe 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.

a) Levellingon the suction flange with a frame level

or on the discharge flange with a levelling
instrument.

b) Admissible defect 0.5 mmfor 1 meter (0.02 in

for 3.3 ft).

c) Wedge under the pump.

Level

Frame
level

4.3 Piping

The user must verify that the equipment is

isolated from any external sources of vibration.

Protective covers are fitted to the

pipe connections to preventforeign bodies entering
during transportation and installation. Ensure that

these covers are removed fromthe pumpbefore
connecting any pipes.

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 pumpand as such would

be outside the terms of the warranty.
Anchor bolts must be appropriate for the foot bolt

holes. Use anchor bolts of accepted standards and
sufficient length so that they may be clamped safely

in the grout.

NFE 27 811

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

concrete gullets.

4.3.1 Suction and discharge piping

The dimensions of the pipes do not directly depend
on suction and discharge diameters of the pump:
a) First, choose a flow speed <2 m/s (7 ft/s) at

suction, andabout 3 m/s (10 ft/s) at discharge.

b) Take into account the available NPSH, which

must be superior to the required NPSH of the
pump.

Never use pump as a support for

piping.

Do not mount expansion joints in

such a way that their force, due to internal pressure,
may act on the pump flange.

Maximumforces and moments allowed on the pump
flanges vary with the pump size and type. These

external strains may cause misalignment, heating of
the bearings, vibrations andthe possible failure of

the pumpcasing.
When designing the pipework (§ 5.3.1, § 5.3.2, §

5.3.3) take necessary precautions in order not to
exceed maximum allowed strains.

Forces and moments applied to the pumpflanges
must never exceed the values shown in the following

f) Control seal and the working of auxiliary piping.

4.4 Electrical connections

4.4.1 Safety conditions about electrical
connections

Electric connections must be carried

out by a qualified electrician, following the local rules
and regulations in force.

It is important to beaware of the EUROPEAN
DIRECTIVE on potentially explosive areas where
compliance with IEC60079-14is an additional

requirement for making electrical connections.

Avoid mechanical, hydraulic or electrical

overload by using motor overload trips or a power
monitor and make routine vibration monitoring.

FM USER INSTRUCTIONS ENGLISH 71576526 - 03/07

Itisimportant to be aware oftheEUROPEAN

DIRECTIVEon electromagnetic compatibility when
wiringupandinstallingequipment onsite.Attention

must be paidtoensurethat the techniques usedduring
wiring/installation do notincrease electromagnetic

emissionsor decreasetheelectromagneticimmunity of
theequipment,wiringoranyconnecteddevices. Ifin

doubt, contactFlowserve foradvice.
Before connecting the electric powersupply, if the

device has been kept in a damp atmosphere, have
the insulation resistance of the electric motor

checked.
This resistance should have a value of not less than

5 000 ohms for each volt of the supply.
Carry out the groundconnections according to the

current local regulations.
The motor must be protected. The protection must

therefore be ensuredby a magneto thermalbreaker
located between the section switch and the motor.

This breaker can beconnected to fuses.
Use a breaker sized and provisionally adjusted to

the current specified on the descriptionplate.
It is recommended to provide the power supply of

the electric motor with a monitoring device allowing
the machine to be shut down safely.

A device to provide emergency stopping shall be
fitted.

4.5 Protection systems

The following protection systems are
recommended particularly if the pump is installed in
a potentially explosive area or is handling a

hazardous liquid. If in doubt consult Flowserve. If
there is any possibility of the systemallowing the

pump to run against a closed valve or below
minimumcontinuous safe flow aprotection device

should be installed to ensure the temperature of the
liquid does not rise to an unsafe level.

5 COMMISSIONING START-UP, OPERATION AND SHUTDOWN

These operations must only be carried out

by 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 disturbedensure that all
the protective guards around the pump coupling and

exposed parts of theshaft are securely fixed.

5.3 Priming and auxiliary supplies

If there are anycircumstances in which thesystem
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 systemcan 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.

Except whenexplicitly 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.

Where there is any risk of the pumpbeing run

against a closed valve generatinghigh liquid and
casing externalsurface temperatures it is

recommended that users fit an external surface
temperature protection device.

Ensure allelectrical, hydraulic,
pneumatic, sealant and lubricationsystems (as
applicable) are connected and operational.

Ensure the inlet pipe andpump
casing are completely fullof 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) Close the discharge valve, fill the pump by

openingthe suction valve. Let air escape by
removing the plug located on the piping.

b) The discharge pipe is headed and there is a by-

pass valve on the check valve, open slightly the
discharge valve and the by-pass of the check

valve.

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

replace the plugs.

5.4 Starting the pump

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.

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

Refer to the rotation arrowof the pump.

e) DO NOT FORGET TO REMOUNT THE

SHIELD GRID ON THE MOTOR STOOL

f) Open all inlet 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 pumpstart-up

Suction valves must be fully open

when pump is running. Never run the pump dry, it
will cause damage.

a) Start motor and check outlet pressure.
b) If pressure is satisfactory, slowly OPENthe

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 fault finding chart for fault
diagnosis.

Priming of a sump suction configuration

with foot valve

* Without foot valve:

Priming may be accomplished by means of venting
system.

Foot valves are not recommended when

the pumped liquid has suspendedsolid particles.
They may lodge between foot valve seat and

shutter.

The pump should run smoothly andwithout
vibration.

The pump must never run at a capacity less than
10 % of the best efficiency point.

Never remove a plug when the pump is

running.

5.5 Running the pump

5.5.1 Venting the pump

Vent the pump to enable all trapped air to

escape takingdue care with hot or hazardous
liquids.

Under normal operating conditions, after the pump
has been fully primedand vented, it should be

unnecessary to re-vent the pump.

5.5.2 Pump fitted with a stuffing box

If the pump has a packed gland there must be some
leakage fromthe 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 willbegin to overheat. If
overheating takes place the pump should be

stopped andallowed to cool before being re-started.
When the pump is re-started it should be checked to

ensure leakage is taking place at the packed gland.

When adjusting an operating stuffing box
(shield grids removed for this operation), the
operator must be very careful. Safety gloves are

compulsory and loose clothes are not allowed
(above all to the arms) to avoid being caught by the

pump shaft.
The pump should be run for ten minutes with steady

leakage andthe gland nuts tightened by 10 degrees
at a time until leakage is reduced to an acceptable

level.
The temperature of the glandshould be checked

after each roundof tightening. If the temperature
starts to climbrapidly 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.

421342002445

4610

With a mechanicalseal, the

maximum temperature is limited to 80 °C (176 °F)
whatever the internalconstruction of the pumpis

(Cast iron or Bronze).

NEVER RUN A MECHANICAL SEAL

DRY, EVEN FOR A SHORT WHILE.

SAFETY INSTRUCTIONS WHEN THE PUMP IS
RUNNING:

If hot or freezingcomponents 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.

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 a mechanical seal

A mechanical seal ensures a seal without leakage
and does not need any adjustment. Nevertheless if a

light leakage occurs during start-up, it should
disappear after theinitial running in of the friction

faces.

If the temperature is greater than 80 °C (176

°F), a warningplate must be clearly placed on the
pump.

It is strictly forbidden to open switch

cupboards, switch boxes, or all other live electric
equipment. If it is necessary to open them in order to

take readings, to carry out tests or adjustments for
example, only a skilled technician may do themwith

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)

Page 20 of 32 flowserve.com

FM USER INSTRUCTIONS ENGLISH 71576526 - 03/07

 Set the alarmat (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 shouldthen remain constant or
marginally reduce with time.

5.5.5 Normalvibration levels, alarm and trip

For guidance, pumps generally fall under a
classification for rigid support machines within the
International rotatingmachinery standards 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.

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 systemoperating

conditions.

5.6 Stopping and shutdown

According to hydraulic conditions of

the installation andits automation degree, stop and
restart procedures can have different forms.

Nevertheless allof them must respect imperatively
the following rules:

5.6.1 Stopping < 1 hour

a) Isolate motor.
b) Avoid reverse rotation of the pump.

c) Make sure that the discharge line pressure does

not reach the foot valve.

5.6.2 Stopping < 1 month

a) Isolate motor.
b) Avoid reverse rotation of the pump.

c) Make sure that the discharge line pressure does

not reach the foot valve.

d) Close the outlet valve. Eventually close the inlet

valve.

e) Switch off external power supply,

flushing/quench, cooling liquid.

5.6.3 Shutdown > 1 month

a) Isolate motor.
b) Avoid reverse rotation of the pump.
c) Make sure that the discharge line pressure does

not reach the foot valve.

d) Close the outlet valve. Eventually close the inlet

valve.

e) Switch off external power supply,

flushing/quench, cooling liquid.

f) Keep the pump fully filled with water. Incase of

pumped liquid other than water, drain the pump
entirely.

g) Turn once per week the pump shaft of one or

two turns.

h) Never restart the pump without carrying out the

verifications recommended before starting (see

§ 5.4.1).

When ambient temperatures are

likely to dropbelow freezing point, the pump and any
cooling andflushing arrangements must be drained

or otherwise protected.

5.6.4 Restarting in continuous running

a) Ensure that the pumpis completely fullof 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 startingfrequency

imposed by the motor manufacturer.

e) Protect the pump against water hammer

when stopping or starting.

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 duringthe life of the

product these may change. The followingnotes may
helpthe 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 andtotal 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.

5.7.2 Viscosity

For a given flow rate the total head reduces with
increased viscosityand 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 pumpspeed, head
varies as speed ratio squared and power varies as

speed ratio cubed. The new duty, however, will also
be dependent on the systemcurve. If increasing the

speed, it is important therefore to ensurethe
maximum pump working pressure is not exceeded,

the driver is not overloaded, NPSHA> NPSHR, and
that noise andvibration 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 thevapor pressure of the

pumped liquid.
NPSHrequired (NPSHR)is the minimumheadrequired

at theimpeller inlet,above thevaporpressure ofthe
pumped liquid,toavoidexcessivecavitationand

extreme performance degradation.
Itis important that NPSHA> NPSHR. The margin

between NPSHA> NPSHRshould beas large as
possible.

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

Ifthe pump has not been specifically orderedfora food
or drinking water applicationit must not beusedfor

these types ofapplications. If it has beenordered for
thistype ofapplicationthe following recommendations

are to be followed.

5.8.1 Cleaning prior to operation

Pumps that areto be usedforafoodor drinkingwater
applicationshould becleaned before being putinto

initial operation andaftertheinstallationof spare parts
thatare incontactwiththe liquid.

Cleaningonce the pump has beencommissionedwill
dependontheapplicationandoperatingconditions.

The user must ensure that thecleaning procedures are
suitable fortheapplicationandoperatingconditions,

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.

It is the plant operator's responsibility to
ensure that allmaintenance, inspection and
assembly work is carried out byauthorized and

qualified personnel who have adequately
familiarized themselves with thesubject matter by

studying this manual in detail (see also section

1.6.2).
Any work on the machine must be performedwhen it

is at a standstill. It is imperative that theprocedure
for shutting down the machine is followed, as

described in section 5.6.

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.

Page 22 of 32 flowserve.com

On completion of work all guards and safety devices
must be re-installed and made operative again.

FM USER INSTRUCTIONS ENGLISH 71576526 - 03/07

Before restartingthe machine, the relevant
instructions listed in section 5, Commissioning, start

up, operation and shut down must 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.
When air or compressed inert gas are used to clean

the machines, the operatorand those people in the
vicinity must be careful and have appropriate gas­protection, wearingat least eye protectors.

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.

d) Verify the condition of the gaskets
e) Gland packing must be adjusted correctly to give

visible leakage and concentric alignment of the
gland follower to prevent excessive temperature

of the packing or follower. Mechanical seals
should present no leakage.

f) Check for any leaks from gaskets and seals.

The correct functioning of the shaft seal must be
checked regularly.

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 fromareas

around close clearances, bearing housings and
motors.

l) Check couplingalignment 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.

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

on the starting device with the words:
"Machine under repair: do not start".

With electric drive equipment, lock the main switch
open andwithdraw any fuses. Put a warning board
on the fuse box or main switch with the words:

"Machine under repair: do not connect".

Never clean pieces withinflammable solvents or
carbon tetrachloride.

Protect yourself against toxic fumes when cleaning
pieces with 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:

a) The pump must be completely vented and

drained andrendered inert before any
disassembly operation.

b) Any auxiliary systems installed must be

monitored, if necessary, to ensurethey function
correctly.

c) During cleaning of the pump ensure the

compatibility between the cleaningproducts and
the gaskets.

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.

6.2.2 Routine inspection (daily/weekly)

The following checks should be made

and the appropriate action taken to remedy any
deviations:

a) Check the behavior of the pump while running:

noise level, vibrations, bearings temperature,
flow rate and pressure.

b) Pumpfitted with a stuffingbox: leakage of 20

drops per minute.
c) Pump fitted with a mechanical seal: no leakage.
d) Check the level and condition of oil lubricant. On

grease lubricated pumps, check running hours

since last rechargeof grease or complete

grease change.

6.2.3 Periodic inspection (6 monthly)

Check pump running records for hourly usage to
determine if bearing lubricant requires changing.

If a check shows a bad running of the

motor pump unit, the user must:
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) ContactFlowserve after-sales Department if the

problem persists.

6.2.5 Gland packing

6.2.5.1 Pump fitted witha packed gland

A well run in and correctly adjusted packinggland
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 packingis supplied as cord the packingmust
be cut so that the external diameter is lightly

tightened and there is an initial gap between the
sleeve and the packing ring.

6.2.4 Mechanical seals

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.

421342002445

42404610

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

(Take precautions to avoid damaging sleeve).

Exampleof straight cut Exampleof bevelcut

Ensure a tightening on the stuffing

box housing and not on the sleeve.

SETTING OF PACKING

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

b) Staggering by about 90° between two pickings.
c) Assemble packingafter packing.

Page 24 of 32 flowserve.com

FM USER INSTRUCTIONS ENGLISH 71576526 - 03/07

After setting the last packing, fix the gland on the
packing and screw up the nut by hand.

After this screwingphase, the shaft should turn by
handas easily as before the settingof the packing.

6.5 Disassembly

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 wearof
the coating during operation and corrosion of the
exposed base metal, dependingon 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 accordingto the supplier's
instructions but will not be held responsible for
coating wear or cracks that may develop over time.
