Piston diaphragm pumps are leak-free oscillating displacement pumps designed for the dosing of volumes up to 1500 l/h and up to maximum 50 bar – depending on flow capacity.

They are an ideal combination of the high supply pressure of a piston pump and the perfect leak-proof diaphragm pump.

Application area
Free-flowing media with aggressive, abrasive, viscous, radio-active, inflammable, odourous or poisonous characteristics.
