Ex-versions mzr-11507 Ex

Beschreibung

Ex-pump for application in chemical and process technology The micro annular gear pump mzr-11507 Ex 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 explosion-proof three-phase AC-motor the pump has a compact design and covers the flow range from 58 ml/min to 1152 ml/min. The mzr-11507 Ex is suitable for continuous delivery 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 in chemical and process technology. Advantages Ex-certification ATEX conform with EU Directive 94/9/EG High dosage precision precision CV < 1 % at low volumes Long service life wear-resistant tungsten carbide Broad viscosity range water, solvents,...
