Duty cycle / impulse operation
KNF pumps are designed for continual use
Short start and stop cycles can change the lifetime 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 front page).
Turning the pump on
In order to guarantee that the pump can start every time it is
advisable to reduce the back pressure down to an acceptable
level. This is also the case if there is a short power cut.
For more specific information contact the KNF specialist (Tele-
phone number: see front page).
Turning the pump off
KNF recommends that after pumping aggressive liquids the
pump should be rinsed thoroughly. (see section 8.2.1), as this
will help to lengthen the lifetime.
Ensure that there are atmospheric pressure conditions in the
system (release the hydraulic pressure).
