MEMDOS GMR Motor-Driven Double 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.
Big motor-driven double diaphragm dosing pump
Double diaphragm dosing pumps of the MEMDOS GMR series can be supplied as single or duplex dosing pumps. The pumps are used to meter large quantities at relatively low back pressures. They are frequently used in waste-water treatment to meter pH-regulating chemicals or flocculents.
