Switching off the pump

➔

KNF recommends: If transferring aggressive liquids, the pump

should be flushed thoroughly prior to switch off (see Chapter
8.2.1), as this will help to lengthen the service life of the dia-
phragm.

➔

Restore the system to normal atmospheric pressure (release

hydraulic pressure in pump).
