Diaphragm Pumps
A diaphragm pump can be used for liquids and gases. It works similar to a plunger pump, however, the flexible diaphragm replaces both, the plunger and the seal so as to obtain a hermetically tight pumping chamber. This avoids leakage of product into the environment and at the same time it prevents environmental impurities from entering the pump (e.g. germs that can affect products in pharmaceutical or food industry). The displacement of the diaphragm can be achieved either hydraulically, pneumatically or mechanically. The design and material of the diaphragms differ accordingly. Diaphragm pumps can also be called membrane pumps.

Pneumatic Diaphragm Pumps
Twin head, double acting pumps used for both aqueous and viscous liquids even if abrasive by solid particles or corrosive by acids or caustic.mem_p01 Pumps are leaktight due to diaphragm design.
Diaphragm Metering Pumps
In stainless steel or PVC with continuously adjustable stroke length for leakfree dosing of liquids. The modular design system allows to compose individual pump units combining several pump mechanisms with various pump heads different in design and/or material of construction.
Diaphragm Pumps for Sludge up to 45 m3/h / up to 15 m head
Dry self-priming up to 7min depth.
Large free passage for solids up to 60mm diameter.
Wetted parts optional made of stainless steel, aluminum, cast iron, bronze or with plastic coating.
Electrical gear motors or combustion engines available as drives.
