Modular series

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 C276, alloy C22 and PEEK™ are the different housing options.

Specification

– small dimensions
– capable for aggressive and corrosive liquids
– capable for low viscous liquids
– for low pressures
– high precision in dosage and repeatability CV 1%
– DC micro motors
