MEMDOS LP 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.

MEMDOS LP

Riding on the crest of the waves

MEMDOS LPThe MEMDOS LP is used when the integration of the pump into controls or control circuits is required. For integration into demanding automation networks, a version with an Ethernet-based MODBUS interface is available. Thanks to the sturdy tappet drive with manual or automatic capacity adjustment, the conveyed media such as acids, lyes, coagulants and flocculants are dosed reliably and precisely. On request, the MEMDOS LP pumps can also be supplied with a double-diaphragm system.
