Failure to supply the bearings and
mechanical
seal with specified
lubrication may result in damage and
premature failure of the pump.
The oil level in the lower bearing sight glass
will be depressed when running.
Check that the rotating assembly is free to
rotate by hand before connecting the power
supply. Also check that the piping system
has been properly connected with all joints
tightened and instrumentation is in position.
When using an electric motor, connect the
electrical supply to the pump unit.
Momentarily switch on motor and check
direction of rotation. This should be such
that the pump assembly turns clockwise
when viewed on the driven end. For three
phase electric motors, if direction of rotation
is incorrect, disconnect the supply and
change over two of three supply wires.
When using a diesel engine verify that the
direction of rotation of the engine is correct
for the pump by reference to the engine
manual.
5.2 Starting Procedure
Open any valves in the discharge pipes to
prevent hydraulic lock from occurring. Start
the engine or switch on the motor and allow
it to build up to full operating speed.
Check that the motor is not overloading,
unit is not vibrating or excessively noisy,
bearings are not overheating, and that the
pump is developing the correct flow and
head requirements.
If the pump is operating at its normal speed,
the pump should be shut down at once if
any of the following defects are found:
a) Excessive vibration.
b) Motor runs hot.
c) Excessive noise from cavitation
d) Pump bearing overheating.
Recommended corrective action for these
faults is given in Section 7 Faults and
Remedial Action.
5.3 During Operation
Hot Surfaces Hazard
Do NOT touch surfaces which during
normal running will be sufficiently hot to
cause injury. Note that these surfaces will
remain hot after the pump has stopped,
allow sufficient time for cooling before
maintenance. Be cautious and note that
other parts of the pump may become hot if
a fault is developing.
Cold Conditions Hazard
Beware of operating water pumps in
temperatures below freezing point, without
first checking that the pumped fluid is not
frozen and the pump is free to turn.
Remember to drain down the pump after
stopping.
Hazardous Noise
In addition to local or site regulations for
noise
protection, SPP Pumps Ltd
recommend the use of Personal Ear
Protection equipment in all enclosed pump
rooms and particularly those containing
diesel engines.
Hazardous Gases, Mists, Sprays and
Leaks
Be aware of the hazards relating to the
pumped fluid, especially the danger from
inhalation of noxious and toxic gases, skin
and eye contact or penetration. Obtain and
understand the hazardous substance data
sheets relating to the pumped fluid and note
the recommended emergency and first aid
procedures.
Periodic Checks:
a) Mechanical Seal Lubrication
Check that the oil level is visible in the sight
glass
and look for evidence of
contamination. Top up or replace seal oil as
required. If oil is regularly lost or
