health and safety personnel, and follow all plant
safety requirements and applicable safety and health
laws and regulations.
1.6.3 Safety action
This is a summary of conditions and actions to
prevent injury to personnel and damage to the
environment and to equipment. For products
used in potentially explosive atmospheres
section 1.6.4 also applies.
NEVER DO MAINTENANCE WORK
WHEN THE UNIT IS CONNECTED TO POWER
GUARDS MUST NOT BE REMOVED WHILE
THE PUMP IS OPERATIONAL
DRAIN THE 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 (482ºF), 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 havesharp corners and the
wearing of appropriate safety gloves andequipment
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.
THERMAL SHOCK
Rapid changes in the temperature of the liquid within
the pumpcan cause thermal shock, which can result
in damage or breakage ofcomponents and should
be avoided.
NEVERAPPLY HEATTO REMOVE
IMPELLER
Trapped lubricant or vapor could causean explosion.
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 enteringthe
immediate area. Note: bearing housings must not be
insulated and drive motors and bearings may be hot.
If the temperature is greater than 68 °C (175 °F)
or below 5 °C (20 °F) in a restricted zone, or
exceeds local regulations, action as above shall
be taken.

HAZARDOUS LIQUIDS
Whenthepump is handlinghazardous liquidscare
must be takento avoidexposure to the liquid by
appropriatesittingof the pump, limitingpersonnel
access and byoperatortraining.Ifthe liquid is
flammable and/orexplosive, strictsafety procedures
must be applied.
Gland packingmust not be used when pumping
hazardous liquids.
PREVENTEXCESSIVE EXTERNAL
PIPE LOAD
Do not use pumpas a support for piping. Do not
mount expansion joints, unless allowed by
Flowserve in writing, so that their force, due to
internal pressure, actson the pump flange.
ENSURE CORRECTLUBRICATION
(See section 5, Commissioning, startup, operation
and shutdown.)
STARTTHE PUMP WITHOUTLET
VALVE PARTOPENED
(Unless otherwise instructed at a specificpoint 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 wherethis situation
cannot occur. Pumpoutlet valve shall may need to
be adjusted to comply with the duty followingthe
run-up process. (Seesection 5, Commissioning
start-up, operation and shutdown.)
NEVER RUN THE PUMP DRY
INLET VALVES TO BE FULLY OPEN
WHEN PUMP IS RUNNING
Running the pumpat zeroflow or below the
recommended minimumflow continuously willcause
damage to theseal.
DO NOT RUN THE PUMP AT
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.
1.6.4 Productsused in potentially explosive
atmospheres
The following instructionsfor pumps andpump
units when installedin potentiallyexplosive
atmospheres must be followed to help ensure
explosionprotection.
The terminology and procedures ensure that the
installed pump is in compliance with the European
Directive 94/9/EC, knownasthe ATEXDirective, which
is mandatory in Europe andmay also be specified in
other countries.Where applicable, bothelectricaland
non-electrical equipment must meet the requirements
94/9/EC.
Evenif theinstallationis ina region where ATEXis not
theapplicable regulation, the generalmeasures
described shall be followedtoensure safeoperation.
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 equipmentonly inthezone for whichitis
appropriate. Alwayscheckthat the driver,drive
couplingassembly, seal and pump equipmentare

WhereFlowserve hassupplied only the bareshaft
pump, the Ex rating applies only to the pump. The
partyresponsible for assembling the pump setshall
selectthe coupling, driver andany additional
equipment, with the necessary CE Declaration of
Conformity establishing it issuitablefor the area in
whichit is to be installed.
The output froma variable frequency drive (VFD)can

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 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 pumpcould 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 hightemperature resulting from
contact between rotating and stationary
components. Furthermore, confinement of liquid in
the pumpand pipes must be avoided (valve closed).
If the liquid heats up this may cause excessive
pressure andlead to bursting of pump components.
Wherethere is anyrisk of the pump being runagainst
a closed valve generating high liquid and casing
externalsurface temperatures it is recommended that
users fit anexternalsurface 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 fromareas around close
clearances, bearinghousings 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 systemis totally filledwith 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 thesystem 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 fromfugitive emissions of
vapor or gas to atmosphere the surrounding area
must be well ventilated.
FM USER INSTRUCTIONS ENGLISH 71576526 - 03/07
Page 8 of 32 flowserve.com
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).
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.
Avoidentrapmentof liquid in the pump andassociated
pipingdue toclosingofsuction anddischargevalves,
which couldcause dangerous excessive pressuresto
occurif thereis heatinputto the liquid. Thiscanoccur
if the pump is stationary or 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 ofa
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 WHICHGIVE 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, cleaningand painting
materials used must not give rise tosparking or
adversely affect the ambient conditions.
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.)

1.9 Noise level
Attention must be given to theexposure 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 cantake 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 dBAtolerance and
cannot be guaranteed.
Similarly the motor noise assumed in the “pump and
motor” noise is that typically expected fromstandard
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 “pumponly” noise
levels in the table should be combined with the level
for the driver obtained from the supplier. Consult
Flowserve or anoise specialist if assistance is
required in combining the values.
It is recommended that where exposure approaches
the prescribedlimit, thensite noise measurements
should be made.
The values are in sound pressure level LpAat 1 m
(3.3 ft) from the machine, for “free field conditions
over a reflecting plane”.
For estimating sound power level LWA (re1 pW)
then add 17 dBA to the soundpressure value.

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/minreduce 1 450 r/min values by 2dBA. For 880 and 720 r/min reduce 1 450 r/min values by 3 dBA.

that whenthe level of thesound 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 devicesagainst 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 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 andwindows, 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 theequipment it must be
checked against the delivery and shipping
documents forits completeness and that there has
been no damage in transportation.
Any shortage and or damage must be reported
immediately to the Flowserve and received in writing
within one month of receiptof the equipment. Later
claims cannot be accepted.
Check any crates, boxes andwrappings for any
accessories or spare parts which may be packed
separately withthe equipment or attached to side
walls of the box orequipment.
Each product has a unique serial number. Check
that this number corresponds with that advisedand
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 fork lift vehicles or slings dependent on their
size andconstruction. See 2.3.1 for positioningof
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 oneor several
suspension rings, only use hooks and chains in
compliance with the local regulations concerning
safety.
Never put cables, chains orropes directly on orin
the suspension rings. Cables, chains or liftingropes
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 when the
direction of thelifting 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 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 swingor fall away.
Never leave aload hanging froma 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 precautionsmust be taken to avoid the
swing of the load, usingfor example two winches
making approximately the same angle, below 30°,
with the vertical.
