OPERATION
5.1
Before Starting
5.1.1
Ensure the pump will be operated within its specification.
5.1.2
Check gearbox oil level. Prior to leaving factory, each pump is filled to
the correct level with the recommended grade of oil (see maintenance
section). Any suggestion of oil loss should be investigated.
5.1.3
Check direction of rotation. Correct direction is clockwise when viewing
pump from top of motor.
5.1.4
Ensure system control or isolating valves in discharge line are open.
5.2
After Starting
5.2.1
Pump will normally prime automatically. However, it may be necessary to
run the pump at maximum capacity to clear air. If this is unsuccessful,
disconnect the discharge pipe work or install a petcock in the discharge
line next to the pump to allow air to escape.
CAUTION
If pumped liquid is hazardous do not disconnect discharge pipe
work. Install a petcock in the discharge line next to the pump and
pipe petcock discharge to suction vessel or drain to avoid spillage.
5.2.2
Check that pump is operating correctly against discharge pressure.
5.2.3
Ensure that any problems are noted and appropriate corrective or
preventative action is taken.

CAPACITY ADJUSTMENT
6.1
Standard manual capacity adjustment is by means of a micrometer. For multiplex
pumps, each pump head is individually controlled by a micrometer located behind
the respective pump head.
6.2
Adjustment should be made whilst the pump is running, though under certain
conditions adjustment is possible when the pump is stopped.
stopped, rotate the flexible coupling by hand to unload the micrometer. This can
be sensed by the ease with which adjustment can be made.
adjust to desired setting.
NOTE
Ensure power supply is disconnected before removing drive-shaft
guard.
