Hydraulic actuated diaphragm head. A double PTFE diaphragm hermetically separates the wetted area from the hydraulic chamber.

During the discharge stroke the diaphragm is balanced by the hydraulic liquid only.

During the suction stroke the diaphragm operation is aided by the mechanical coupling. This combined principle offers an extraordinary suction lift capability of the Mf pump.

Integrated in the hydraulic chamber are the pressure relief valve and an automatic venting valve.

The valveless forced reflow of the internal oil leakage operates wearfree and guarantees optimum metering accuracy.

The pump check valves are of cone type. This guarantees low wear, short pressure loss (NPSHR) and self-cleaning.

All wetted parts (except for the PTFE (diaphragm) are fabricated from stainless steel.
