The sign is not a safety symbol but
indicates an important instruction in the assembly
process.
This symbol indicates potential risks
connected with extremely high temperatures.
This symbol indicates potential risks
connected with extremely low temperatures.
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 avoid 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 be adjusted to comply
with the duty following the run-up process (See
section 5 Commissioning, startup, operation and
shutdown).
START THE PUMP WITH
OUTLET VALVE FULLY OPEN
This is recommended to avoid the risk of overloading
and damaging the pump motor where greater power
is taken at low or shut off flow. Pump outlet valve
shall be adjusted to comply with the duty following the
Page 5 von 32
MSP USER INSTRUCTIONS ENGLISH 11/10
run-up process (See section 5 Commissioning,
startup, operation and shutdown).
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 back pressure on the pump may
overload the motor and cause cavitation. Low flow
rates may cause a reduction in
overheating of the pump, instability and
cavitation/vibration.
When ambient temperatures are
likely to drop below freezing point, the pump and any
cooling and flushing arrangements must be drai ned
or otherwise protected.

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 lbs) use a crane
corresponding to the mass and in accordance with
current local regulations.
NEVER DO MAINTENANCE WORK WHILST THE
UNIT IS CONNECTED TO POWER
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.
condition these are extremely dangerous and skin
contact must be avoided.
GUARDS MUST NOT BE REMOVED WHILE
PUMP IS OPERATIONAL
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 b e
avoided.
NEVER APPL Y HEAT TO REMOVE
IMPELLER
Trapped lubricant or vapour could cause an
explosion.
HOT AND COLD PAR TS
If hot or freezing components or auxiliary heating
supplies can present a danger to operators, they
must
be shielded to avoid accidental contact. If
complete protection is not possible, the machine
access must be limited to maintenance staff only.
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 (41°F) in a restricted zone, or exceeds
local regulations, action as above shall be taken.
1.6.4 Products used in potentially explosive
atmospheres
Measures are required to:
• Avoid excess temperature
• Prevent build up of explosive mixtures
• Prevent the generation of sparks
• Prevent leakages
• Maintain the pump to avoid hazard
The following instructions for pumps and pump units
when installed in potentially explosive atmospheres
must be followed to help ensure explosion protection.
Both electrical and non-electrical equipment must
meet the requirements of European Directive
94/9/EC.
1.6.4.1 Scope of compliance
DRAIN 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 °C (482 ºF), partial decomposition of fluoroelastomers (example: Viton) will occur . In this
Page 6 von 32
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
MSP USER INSTRUCTIONS ENGLISH 11/10
party responsible for assembling the pump set shall
select the coupling, driver and any additional
equipment, with the necessary CE Certificate/
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 pump sets with a VFD, the ATEX Certification for
the motor must state that it covers the situation where
electrical supply is from the VFD. This is 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.

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 when the pump is
required to be used in differently classified potentially
explosive atmospheres. In this case the user is
responsible for ensuring that the pump surface
temperature does not exceed that permitted in its
actual installed location.
Do not attempt to check the direction of rotation with
the coupling element/pins fitted due to the risk of
severe contact between rotating and stationary
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 or a Power Monitor and
make routine vibration monitoring.
In dirty or dusty environments, regular checks must
be made and dirt from areas around close
clearances, bearing housings and motors.
Maximum surface temperature (Tempe rature Class)
(see section 1.6.4.3)
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 and bearings and due to the minimum
permitted flow rate is taken into account in the
temperatures stated.
1.6.4.4 Preventing the build up of explosive
mixtures
ENSURE THE PUMP IS PROPERLY FILLED
AND VENTED AND DOES NOT RUN DRY
Ensure the 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 a Power Monitor).
To avoid potential hazards from fugitive emissions of
vapour or gas to atmosphere the surrounding area
must be well ventilated.
Page 7 von 32
1.6.4.5 Preventing sparks
To prevent a potential hazard from mechanical
contact the coupling guard must be non-sparking and
anti-static.
To avoid the potential hazard from random induced
current generating a spark the earth contact on the
baseplate must be used.
Avoid electrostatic charge: do not rub nonmetallic surfaces with a dry cloth; ensure cloth is
damp.
The coupling must be selected to comply with
94/9/EC and correct alignment must be maintained.
1.6.4.5 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 suction and
discharge valves, 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.
1.6.4.6 Maintenance to the centrifugal pump 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
MSP USER INSTRUCTIONS ENGLISH 11/10
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).to
include the following.
a) Any auxiliary systems installed must be
monitored, if necessary, to ensure they function
correctly.
b) 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.
c) Check for any leaks from gaskets and seals. The
correct functioning of the shaft seal must be
checked regularly
d) Check bearing lubricant level, and if the hours run
show a lubricant change is required.
e) Check that the duty condition is in the safe
operating range for the pump.
f) Check vibration, noise level and surface
temperature at the bearings to confirm
satisfactory operation.
g) Check dirt and dust is removed from areas
around close clearances, bearing housings and
motors.
h) Check coupling alignment and re-align if
necessary.

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.
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 L
m (3.3 ft) from the machine, for “free field
conditions over a reflecting plane”.
For estimating sound power level L
WA
then add 14 dBA to the sound pressure value.
