7.6 SHORT-TERM SHUTDOWN
If the pump has switched off correctly and has not suddenly come to a halt, it may be re-started without
the need to take any special measures.
If the pump comes to a sudden halt, or if the pump was switched off because of a possible danger, it
must be checked for damage.
7.7 LONG-TERM SHUTDOWN
1. Follow the stopping procedure described in SECTION 7.5-STOPPING.
2. Disconnect the vent filter and seal openings on the bearing frame to lessen the exchange of
air.
3. While the unit is idle:
a. If the plant is in an operational state, warm up and start the unit at monthly
intervals (see SECTION 7.2-STARTUP for details).
b. If the plant is not in an operational state, turn the unit over by hand a couple of
times at monthly intervals, ensuring the shaft is not returned to the same position,
to allow the bearings to rest in a different position every time.
4. If there is danger of freezing, drain the pump, drain the oil from the pump bearings and all
the auxiliary piping.
5. Change the oil before recommencing operation, ensuring the correct grade and the correct
volume has been filled in the bearing frame (see SECTION SIX - LUBRICATION for details).
