Modular pump series

Resistant customized dosing pump

The micro annular gear pump mzr-2942 of the modular series is suitable for dispensing and metering of aggressive or corrosive liquids. Equipped with oxide ceramic bearings, the material configuration of the pump body as well as of the rotors can be individually selected. Depending on the nature of the delivered liquid, a choice of different resistant components allows a customized configuration. The rotors are available in ZrO2-ceramics or in tungsten carbide. Alloy C22 and PEEK™ are the different housing options.
