Motor-driven Diaphragm Dosing Pumps

Diaphragm dosing pumps are leak-free, and are therefore suitable for highly aggressive or toxic media. Depending on the gear type, the diaphragm allows pressures up to 16 bar. Diaphragm dosing pumps are fitted with a separation chamber as standard. If a crack forms in the diaphragm due to wear, this prevents the medium from flooding the system components or the pump itself. The medium is controlled and flows through a downpipe to the collecting basin. The medium sides of the diaphragms are coated with PTFE.

The dosing quantity can be doubled by using two dosing heads. The largest motor-driven diaphragm dosing pump (Type GMR) has a hydraulically coupled double-diaphragm system.
