3.4.8 Coupling –
As soon as the flexible elements of the shaft connection show signs of wear
[abrasion], these parts have to be replaced. Verify the alignment of the shaft ends.
3.5 SHUT DOWN:
Do not close the shutoff valve on the discharge side until the pump has come to a
complete standstill.
Switch off the driver.
The shutoff valves need not be closed if non-return valves are fitted.
The shutoff valve on the suction side is to be closed both during prolonged
standstill of the pump and if there is an overpressure on the suction side [positive
suction].
Shut down all auxiliary facilities [cooling liquid, etc]. The shaft seal on pumps
pumping liquid under vacuum has to remain wetted by the sealing liquid also during
standstill.
If there is a danger of frost, protect the pump, cooling circuit, etc against freezing
or drain off the liquid.
