10.5 Replacing the pump head, diaphragm and protective diaphragm
Personnel:
Protective equipment:
CAUTION!
Diaphragm:
– Before changing the diaphragm, the pump must always be placed in
maintenance mode, see
position' on page 57 .
– Only tighten diaphragms by hand and do not use any tools .
The service life of the diaphragm depends on the following:
– back pressure
– operating temperature
– and metering medium
We recommend changing the diaphragms after max. 400 operating hours
or annually. The replacement intervals are, however, dependent on the
abrasiveness of the substances to be metered.
You should conduct extra checks in extreme operating conditions.
