Micro annular gear pump mzr-11507

For industrial production and process technology

The micro annular gear pump mzr-11507 is equipped with tungsten carbide rotors and bearings. Hard construction material and precision manufacturing techniques guarantee excellent dosage precision, high service life and wear resistance for low volume dosage of non-lubricating liquids. Driven by a high-power three-phase AC-motor the pump has a compact design and covers the flow range from 29 ml/min to 1152 ml/min. The mzr-11507 is suitable for continuous delivery and discrete dosage of low and high viscosity liquids. It achieves high differential pressures and provides a low pulsation flow. Its robustness and the available accessories make it suitable for challenging applications.
