4.1. Replacement of diaphragm, valves and o-rings
The replacement of the diaphragm and the valves can be conducted by the operator. The following
drawings describe it step-by-step (maintenance kit PSKITQF12MU).
In case of bursting diaphragms by overpressure we advice also to change the bearing unit
(PSKITWLC123 or PSKITWLC125 resp. PSKITWLC125-CV for the CV compact model, see chapter
4.2.).
