pump down and recheck alignment while the
pump is hot. Piping thermal expansion may
change the alignment. Realign pump as
necessary.
5 COMMISSIONING, START-UP,
OPERATION AND SHUTDOWN
These operations must be
carried out by fully trained and qualified
personnel.
5.1 Pre-commissioning procedure
Long coupled bearing frames are
shipped without oil. For long coupled pumps, fill
the bearing housing [3200] with correct grade of oil
to the correct level, according to Section 6.15.
5.2 Direction of rotation
Correct rotation is indicated by the
arrow on the casing [1100]. Improper rotation will not
damage the pump however, performance is greatly
reduced. Rotation may be determined by viewing the
motor’s fan.
Do not bump the motor to test
rotation or run the pump without the suction
completely flooded. Dry running can damage the
pump in a matter of seconds if the pump is not
equipped with dry-run bearings.
If maintenance work has been
carried out to the site's electricity supply, the
direction of rotation should be re-checked in case
the supply phasing has been altered.
5.3 Priming and auxiliary supplies
5.3.1 Auxiliary supplies
Ensure all electrical, hydraulic,
pneumatic, sealant and lubrication systems (as
applicable) are connected and operational.
5.3.2 Filling and priming
Ensure inlet pipe and pump casing
[1100] is completely full of liquid before starting
continuous duty operation.
Priming may be carried out with an ejector, vacuum
pump, interceptor or other equipment, or by
flooding from the inlet source.
When in service, pumps using inlet pipes with foot
valves may be primed by passing liquid back from
the outlet pipe through the pump.
5.4 Starting the pump
a) CLOSE the discharge valve.
Fully open the suction valve. Pump requires a
flooded suction.
b) Do not operate pump with suction valve
closed. Operating pump more than a few
minutes after suction valve closed may cause
bearing failure.
c) Fully open discharge valve to complete priming.
Turn back the discharge valve until it is 1/4 to 1/2
open. TB-
MAG™ pumps operate safely with
discharge valve partially open.
d) Continuous operation against a closed
discharge valve may cause pump to overheat.
e) Start motor and check the outlet pressure.
f) If the pressure is satisfactory, SLOWLY open
the outlet valve.
g) Do not run the pump with the
outlet valve closed for a period longer than 10
seconds.
h) If NO pressure, or LOW pressure, STOP the
pump. Refer to section 7, Troubleshooting, for
fault diagnosis.
5.5 Running the pump
Care must be taken when operating pump.
Safety gloves are essential. Loose clothing must
not be worn.
External flush or quench should be
started before the pump is run and allowed to flow for
a period after the pump has stopped.
5.5.1 Normal vibration levels, alarm and trip
For guidance, pumps generally fall under a
classification for rigid support machines within the
International rotating machinery standards and the
recommended maximum levels are based on those
standards.
