MEMDOS LB

Motor-driven diaphragm dosing pump — manual stroke adjustment

Manufacturer: Lutz-Jesco Dosing Pumps & Skids

The MEMDOS range of motor-driven diaphragm dosing pumps covers 4 – 1020 l/h at pressures up to 16 bar. The sturdy tappet drive doses media such as acids, lyes, coagulants and flocculants reliably and precisely. Two sizes are available: the first covers 0 – 156 l/h, the second 0 – 1020 l/h.

The MEMDOS LB is the basic model of the series with manual stroke length adjustment. The wide range of available motors means it can be deployed from simple applications through to integration in complex plant systems, and versions for explosive atmospheres are available.
