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:
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 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.
1.6.3 Safety action
This is a summary of conditions and actions to
prevent injury to personnel and damage to the
environment and to equipment. For products
used in potentially explosive atmospheres
section 1.6.4 also applies.
NEVER DO MAINTENANCE WORK
WHEN THE UNIT IS CONNECTED TO POWER
GUARDS MUST NOT BE REMOVED WHILE
THE PUMP IS OPERATIONAL
DRAIN THE PUMP AND ISOLATE
PIPEWORK BEFORE DISMANTLING THE PUMP
The appropriate safety precautions should be taken
where the pumped liquids are hazardous.
FLUORO-ELASTOMERS (When fitted.)
When a pump has experienced temperatures over
250 ºC (482 ºF), partial decomposition of fluoroelastomers (example: Viton) will occur. In this
condition these are extremely dangerous and skin
contact must be avoided.
HANDLING COMPONENTS
Many precision parts have sharp corners and the
wearing of appropriate safety gloves and equipment
is required when handling these components. To lift
heavy pieces above 25 kg (55 lb) use a crane
appropriate for the mass and in accordance with
current local regulations.
THERMAL SHOCK
Rapid changes in the temperature of the liquid within
the pump can cause thermal shock, which can result
in damage or breakage of components and should
be avoided.
NEVER APPLY HEAT TO REMOVE
IMPELLER
Trapped lubricant or vapor 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.
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.
Page 5 of 36
®
MEN USER INSTRUCTIONS ENGLISH 71576288 – 11-09
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.)
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
NEVER RUN THE PUMP DRY
INLET VALVES TO BE FULLY OPEN
WHEN PUMP IS RUNNING
Running the pump at zero flow or below the
recommended minimum flow continuously will cause
damage to the seal.
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 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).
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.

MEN USER INSTRUCTIONS ENGLISH 71576288 – 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.
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.
In areas where the staff has to intervene, remember
that when the level of the sound pressure is:
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.
Note all reserves on the signed shipping note which
is given back to the hauler. 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 quotes 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.
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.
Page 7 of 36
®
MEN USER INSTRUCTIONS ENGLISH 71576288 – 11-09
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.
2.2.2 Pump masses
The masses of the pumps bare end of shaft are
shown on the nameplate.
All motors (for masses see the motor description
plate) must be handled with a winch.
Motor pump unit
Bareshaft pump
For masses above 25 kg (55 lb), manual
handling is forbidden.
2.3 Lifting
2.3.1 Slinging of motor pumps units
Use handling means in accordance with motor
pump unit mass mentioned on the CE plate. For the
masses of the pumps bare end of shaft see table §
2.2.2 and nameplate.
To avoid distortion, the pump unit
should be lifted as shown.
Components weighing less than 25 kg (55 lb)
can be handled manually following the correct
actions and using the correct posture.
When handling always wear gloves, safety
boots and an industrial safety helmet.
For masses above 25 kg (55 lb), manual
handling is forbidden.
2.4 Storage
Store the pump in a clean, dry
location away from vibration. Leave piping
connection covers in place to keep dirt and other
foreign material out of pump casing. Turn pump at
intervals to prevent brinelling of the bearings and the
seal faces, if fitted, from sticking.
Do not store pumps starting on the fan guard.
The pump may be stored as above for up to 6
months. Consult Flowserve for preservative actions
when a longer storage period is needed.

4 INSTALLATION
4.1 Location
The pump should be located to allow room for
access, ventilation, maintenance and inspection with
ample headroom for lifting and should be as close as
practicable to the supply of liquid to be pumped, and
to the venting system.
Disconnect the switching enclosure support from the
pump support by removing the fastening bolts. The
switching enclosure support must be off-set with
respect to the pump motor base.
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. The base plate
should be mounted onto a firm foundation, either an
appropriate thickness of quality concrete or sturdy
steel framework. It should NOT be distorted or pulled
down onto the surface of the foundation, but should
be supported to maintain the original alignment.
Anchor bolts must be in accordance with the foot
bolt holes. Use anchor bolts of accepted standards
and sufficient to ensure safe fitting in the foundation.
Particularly, this applies to individual plates where
the anchor bolts have to withstand the driving
torque.
Provide sufficient space in the foundation to
accommodate the anchor bolts. If necessary,
provide concrete risers.
4.2.1 Setting the base plate for anchoring
- Clean the foundation surface thoroughly.
- Put shims on the foundation surface (approx 20-25
mm thick), one on each side of the bolt hole (as an
alternative, leveling screws can be used).
- Lay the base plate and level in both directions with
extra shims. The base plate should be level to within
0.5 mm per 1 m.
If anchor bolts have been pre-cast in the foundation
slightly tighten the anchor bolts. Otherwise let them
hang in the foundation holes.
4.3 Grouting
