Modular pump series Micro annular gear pump mzr®-7245 Fluid-dependent customizable dosing pump

– Customized material selection pump components in stainless steel/tungsten carbide, aluminium/tungsten carbide or alloy C22/ceramics

– High dosage precision precision CV 1 % at low volumes

– Long service life wear- and corrosion-resistant materials

– Compact dimensions length 160 mm, including controller

– Dynamic smart drive and control DC-servomotor with integrated microcontroller

– Low pulsation delivery, low shear stress rotary micro annular gear technology, no valves

The micro annular gear pump mzr-7245 of the modular pump series is suitable for dosing and metering in low to medium pres-sure and viscosity ranges. To the

main assets of this series belong low pulsation, high precision low volume dosage of non-lubricating liquids, compact design with smallest dimensions and low price.

These pumps are suitable for dos-ing and dispensing deionized wa-ter, aqueous solutions, solvents as well as low to highly viscous oils, lubricants or dyes.
