How the piston diaphragm pumps work

The energy is transferred from the drive unit to the piston, which is guided in a liner. The piston transmits the stroke movement to the diaphragm via a hydraulic or working fluid. During the suction stroke, the suction valve opens due to the resulting vacuum and the pumped medium flows into the diaphragm housing. During the pressure stroke, the pumped medium is pressed out through the pressure valve into the pressure line.
