Plunger pump MEMDOS LP

for alkalisacidfor chemicals

Product information
The MEMDOS LP is a dosing pump intended for integration into control systems and regulation loops. An Ethernet-based MODBUS interface is available for connection to advanced automation networks. With a robust tappet (plunger) drive and manual or automatic capacity adjustment, the unit reliably doses a wide range of media such as acids, alkalis, precipitants and flocculants. A double diaphragm system is available on request.
