Motor-driven Diaphragm Pumps

Diaphragm dosing pumps are leak-free and therefore also suitable for highly aggressive or toxic media. Depending on the type of transmission, the diaphragm allows pressures up to 16 bar. Membrane metering pumps are fitted as standard with a separation chamber which, in the event of a wear-induced diaphragm cracking, prevents the medium from flooding the pump itself or parts of the system. It is directed to the collecting basin in a controlled manner via a downpipe. The membranes are PTFE-coated on the medium side.

A doubling of the dosing quantity is possible with the use of two dosing heads. The largest motor diaphragm dosing pump type GMR has a hydraulically coupled double diaphragm system.
