Switching on the pump
➔
In order to guarantee that the pump can start every time it is
advisable to reduce the back pressure to an acceptable level. If
you experience a brief power interruption, check for the pres-
ence of pressure or vacuum before restarting.
For more specific information contact your KNF technical
adviser.
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).
