1.6 Safety

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:

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.

This symbol indicates electrical safety
instructions where non-compliance will involve a
high risk to personal safety or the loss of life.

This symbol indicates safety instructions where
non-compliance would affect personal safety and
could result in loss of life.

This symbol indicates “hazardous substances
and toxic fluid” safety instructions where non­compliance would affect personal safety and could
result in loss of life.

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.

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 non­compliance in the hazardous area would cause the
risk of an explosion.

This sign is not a safety symbol but indicates

an important instruction in the assembly process.

1.6.2 Personnel qualification and training

All personnel involved in the operation, installation,
inspection and maintenance of the unit must be
qualified to carry out the work involved. If the
personnel in question do not already possess the
necessary knowledge and skill, appropriate training
and instruction must be provided. If required the
operator may commission the manufacturer/supplier
to provide applicable training.

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.

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 APPLY HEAT TO REMOVE
IMPELLER
Trapped lubricant or 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 (155 °F)
or below -5 °C (23 °F) in a restricted zone, or
exceeds local regulations, action as above shall
be taken.

Page 5 de 32

VF USER INSTRUCTIONS ENGLISH 71561233 - 11/09

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.

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

Where applicable, both electrical and non-electrical
equipment must meet the requirements 94/9/EC.

Even if the installation is in a region where ATEX is
not the applicable regulation, the general measures
described shall be followed to ensure safe operation.

The measures are explained under the headings of:
Avoiding excessive surface temperature.
Preventing build up of explosive mixtures.
Preventing the generation of sparks.
Preventing leakages.
Maintaining the pump to avoid hazard.

1.6.4.1 Scope of compliance

Use equipment only in the zone for 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.

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.

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.

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.

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.

1.6.4 Products used in potentially explosive
atmospheres

The following instructions for pumps and pump
units when installed in potentially explosive
atmospheres must be followed to help ensure
explosion protection.

The terminology and procedures ensure that the
installed pump is in compliance with the European
Directive 94/9/EC, known as the ATEX Directive,
which is mandatory in Europe and may also be
specified in other countries.

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 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.

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
external surface temperatures it 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

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.

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

Where applicable the coupling must be selected to
comply with 94/9/EC and correct alignment must be
maintained.

Additional requirements for metallic pumps on
non-metallic baseplates.

When metallic components are fitted on a non­metallic baseplate they must be individually earthed
(grounded).

Page 7 de 32

VF USER INSTRUCTIONS ENGLISH 71561233 - 11/09

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 the discharge valve, 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.

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

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

1.7 Nameplate and safety labels

been supplied separately to the purchaser these
should be obtained and retained with these User
Instructions if required.

Page 8 de 32

VF USER INSTRUCTIONS ENGLISH 71561233 - 11/09

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 by an
inverter may show an increased noise at some
speeds.
If a pump unit only has been purchased for fitting
with your own driver then the “pump only” noise
levels in the table should be combined with the level
for the driver obtained from the supplier. Consult
Flowserve or a noise specialist if assistance is
required in combining the values.

It is recommended that where exposure approaches
the prescribed limit, then site noise measurements
should be made.
The values are in sound pressure level LpA at 1 m
(3.3 ft) from the machine, for “free field conditions
over a reflecting plane”.

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

1 The noise level of machines in this range will most likely be of values which require noise exposure control, but typical values are inappropriate.

Note: for 1 180 and 960 r/min reduce 1 450 r/min values by 2 dBA. For 880 and 720 r/min reduce 1 450 r/min values by 3 dBA.

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.

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.

The condition of minimum submergence
must be respected. Level control shall be fitted in
the sump to prevent liquid level dropping below
minimum acceptable.

All equipment must be grounded.

4.1 Location

The pump should be located to allow room for
access, ventilation, maintenance and inspection
with ample headroom for lifting.

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.

Page 14 de 32

NF E 27 811

If the pump is set on a tank, make sure that the
connection flange is perfectly flat and horizontal. If
the assembling is on a concrete stone or a metallic
structure, be sure of the flatness and rigidity of the
unit.

If the pump is mounted on a recently sunk well, the
soil round the well may not be stabilized. After
some times, check perpendicularity and level, and
if needed, adjust before definitive anchoring.

The anchoring frame will then be fixed
provisionally.
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.

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

4.4 Initial alignment

Before connecting the couplings

verify the motor rotation direction.

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.

k) Check that the rotor is free to

rotate manually.

Page 16 de 32

VF USER INSTRUCTIONS ENGLISH 71561233 - 11/09

4.4.2 Alignment methods

Ensure pump and driver are isolated
electrically and the half couplings are
disconnected. Ensure that the pump pipe work,
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.

Alignment
Parallelism and concentricity check

with a rule

with a comparator

If the motor stool is fitted with a
screw adjustment, take 3 or 4 measurements at
different places.

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

Otherwise: there are no coupling checks regarding
parallelism or concentricity. Owing to the design of
the machine the set is self-aligning.

4.5 Piping

The user must verify that the equipment is

isolated from any external sources of vibration.

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.
Greater forces or moments may cause
misalignment, hot bearings, worn couplings,
vibrations and the possible failure of the pump
casing.

When designing the pipes (§ 4.5.2) take
necessary precautions in order not to exceed the
maximum allowed forces.

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

4.5.2 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.

Do not tighten flanges before the
final check (see § 4.5.3).

4.5.3 Final checks

a) Check the tightening of anchor bolts. Tighten

them if necessary.

b) Check that protective covers on suction and

discharge flanges are removed.

c) Check that holes of pipe work flanges are

parallel and correspond to those of the pump.

d) Tighten discharge flange.
e) 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 re­examined.

f) If it provided, connect auxiliary pipe systems

(hydraulic, pneumatic, sealing system).

g) Control tightness and functionality of auxiliary

pipings.

4.6 Electrical connections

4.6.1 Safety conditions about electrical
connections

Ensure piping and fittings are

flushed before use.

Ensure piping for hazardous liquids
is arranged to allow pump flushing before removal
of the pump

Page 18 de 32

Electric connections must be carried
out by a qualified electrician, following the local
rules and regulations in force.

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.

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 doubt, contact
Flowserve for advice.

VF USER INSTRUCTIONS ENGLISH 71561233 - 11/09

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. 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 (§ 5.4.1) and before the first start (§

5.4.2).

4.7 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.

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 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

5.5.3 and 5.5.4.
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 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 disturbed ensure
that all the protective guards around the pump
coupling and exposed parts of the shaft are
securely fixed.

5.3 Priming and auxiliary supplies

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.

Page 19 de 32

VF USER INSTRUCTIONS ENGLISH 71561233 - 11/09

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 ring overheating.

d) Install all protection systems

and more particularly the shield grid of the
gland packing [9610.01] and the coupling
guard [9610.02].

e) Check that the liner spraying and filling lines

are effectively connected to the clean water

distribution network.
f) Close the valve at discharge.
g) Check the direction of rotation of the motor.

Refer to the rotation arrow of the pump.
h) Check that the motor bearings are correctly

greased.
i) Make sure that the ventilating grate is not

obstructed or too near to a wall or an obstacle.

5.4.2 First pump start-up

a) Before starting, the flushing valves of the seals

(if existing) must be opened.
b) The flushing valves of the bearing liner must

be opened.
c) Start motor and check outlet pressure.
d) If pressure is satisfactory, slowly OPEN the

outlet valve.

e) Do not run the pump with the

outlet valve closed for a period longer than 30

seconds.
f) If NO pressure, or LOW pressure, STOP the

pump. Refer to fault finding chart for fault

diagnosis.
The pump should run smoothly and without

abnormal vibration (see page 21)
The pump must never run at a capacity of less

than 40% of that at the best efficiency.

Never remove a plug when the pump is

running.
When the unit is normally running, note the

maximum intensities absorbed on each phase.
Adjust definitively the circuit breaker for a slightly
greater current to the maximum noticed current,
which must never be superior to the currents,
indicated on the motor description plate. Check
that the voltage between phases in the motor
terminals is correct.

A well adjusted and maintained circuit breaker
efficiently protects the pump unit. Any disjunction
means that the unit is badly running (voltage loss,
cut phase, misadjustment, foreign matter in the
pump, jamming, etc...).

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.

5.5.2 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 stopped and allowed to cool before
being re-started. When the pump is re-started it
should be checked to ensure leakage is taking
place at the packed gland.

When adjusting an operating stuffing box
(shield grids removed for this operation), the
operator must be very careful. Safety gloves are
compulsory and loose clothes are not allowed
(above all to the arms) to avoid being caught by
the pump shaft.

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.

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.

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.

Page 20 de 32

VF USER INSTRUCTIONS ENGLISH 71561233 - 11/09

The adjusting lines, the stuffing box, the lines
under pressure or the mechanical seal cooling
lines must be protected against external knocks.

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
protection against electrical risks are used.

5.5.3 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.

5.5.4 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.

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 system
operating conditions.

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) Avoid a continuous running below the

authorized flow rate (see § 5.4.2).

Restart:
a) Ensure a continuous supply with a sufficient

available NPSH.

b) Ensure a back pressure so that the motor

power is not in excess.

c) Respect the starting frequency

imposed by the motor manufacturer.

d) Protect the pump against water hammer

Page 21 de 32

when stopping or starting.

VF USER INSTRUCTIONS ENGLISH 71561233 - 11/09

Shutdown:

Close the outlet valve and stop the

motor.

For prolonged shut-downs and
especially when ambient temperatures are likely to
drop below freezing point, the pump must be
drained or otherwise protected.

Switch off flushing and/or cooling/ heating liquid
supplies at a time appropriate to the process.

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)

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 over­pressurize the pump.

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 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.

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. 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.
It is important that NPSHA > NPSHR. The margin
between NPSHA > NPSHR should be as large as
possible.

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.

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.

5.8.1 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 22 de 32

VF USER INSTRUCTIONS ENGLISH 71561233 - 11/09

6.2 Maintenance schedule

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 restarting the machine, the relevant
instructions listed in section 5, Commissioning,
start up, operation and shut down must be
observed.

An oil, grease or liquid leakage may make the
ground slippery. The maintenance of a
machine 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 operator and those people
in the vicinity must be careful and have appropriate
gas-protection, wearing at least eye protectors. DO
NOT SPRAY air or compressed inert gaz 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 pieces with inflammable solvents or
carbon tetrachloride. Protect yourself against toxic
fumes when cleaning pieces with cleaning agents.

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 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.

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.

6.2.2 Routine inspection (daily / weekly)

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

a) Check the behaviour of the pump while

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

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) Check the level and condition of oil lubricant.

On grease lubricated pumps, check running
hours since last recharge of grease or
complete grease change.

6.2.4 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).

Example of straight cut Example of bevel cut

Ensure a tightening on the stuffing

box housing and not on the sleeve.

SETTING OF PACKING

Follow the instructions:
a) Assembly of the packing in S.
b) Staggering by about 90° between two

packings.

c) Assemble packing after packing.

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

After this screwing phase, the shaft should turn by
hand as easily as before the setting of the
packings.

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

.
