Adjusting hose compression force
(shimming)
Fitting and removing shims is a simple action which can
be carried out via the inspection window on the front of
the pump housing. The pump hose or the pump cover
does not need to be removed. In order to determine the
correct number of shims for your specific application
refer to §
.
CAUTION
Too many shims, this means a too high
compression force on the pump hose, cre-
ate a too high load on the pump head and
pump hose, which results in a reduction of
the life of the pump hose and bearings.
