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

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

1.6.4.3 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

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.

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.
