Duty cycle / impulse operation
KNF pumps are designed for continuous operation.
Short start and stop cycles may adversely affect the service life of
the brushed motors.
If the pump is operated with short cycles in your application,
please contact a KNF pump specialist for further information
(Telephone number: see first page).
Turning the pump on
➔
In order to guarantee that the pump can start every time it is
advisable to reduce the back pressure to an acceptable level.
This is also the case if there is a short power cut.
For more specific information contact the KNF specialist
(Telephone number: see first page).
Turning the pump off
➔
KNF recommends: if pumping aggressive liquids, the pump
should be rinsed thoroughly prior to switch off (see Section
8.2.1), as this will help to lengthen the service life of the
diaphragm.
➔
Ensure that the system is subject to normal atmospheric
pressure (release the hydraulic pressure).
