High performance pump series mzr-11508X1


For industrial production and process technology The micro annular gear pump mzr-11508X1 is equipped with tungsten carbide rotors and bear-ings. 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 DC-motor the pump has a compact design and covers the flow range from 0.19 ml/min to 1152 ml/min. The mzr-11508X1 is suitable for continuous delivery and discrete dosage of 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. Advantages High dosage precision precision CV < 1% at low volumes Long service life wear-resistant tungsten carbide Broad viscosity range methanol, water, solvents, adhesives, grease, gel Dynamic precision motor brushless DC-motor with encoder Compact dimensions length...
