Seats

Center shafts and connecting shafts carry the diaphragms and transmit the reciprocating movement across the pump. Corrosion, wear at the diaphragm mounting face or bending from mis-installation can all shorten diaphragm life. We offer replacement AODD shafts machined to correct OEM dimensions so that diaphragms seat properly and the pump runs true. Installing a new shaft during a full rebuild can significantly extend the time between failures.
