4.3 Running
While the pump is running, a periodic inspection should be made of:

lubricate the packing.
b) Bearings. Check the bearings for temperature, which should not exceed pumped
liquid temperature or 80 Deg. C whichever is the lower.
c) With mechanical seal fitted pumps, check that there is no leakage from the
stuffing box.
d) Suction and discharge gauge readings.
4.4 Stopping
a) Slowly close delivery valve and shut down driving unit in accordance with
manufacturer’s instructions.
b) Shut off external sealing liquid supply, if supplied, to relieve stuffing box pressure.
c) Successful operation of the pump depends on accurate alignment. It is
recommended to re-check the alignment after preliminary run.
