Micro annular gear pump mzr-7208 - 1

High performance series Micro annular gear pump mzr®-7208 For industrial production and process technology High dosage precision precision CV < 1% at low volumes High differential pressures achievable even for low viscosity liquids Long service life wear-resistant tungsten carbide Broad viscosity range methanol, water, solvents, adhesives, grease, gel Compact dimensions length 211 mm Dynamic precision motor brushless DC-motor with encoder Low pulsation delivery, low shear stress rotary micro annular gear technology The micro annular gear pump mzr-7208 covers the flow rate range 0.048-288 ml/min. To the main assets of the device belong high precision, low pulsation, low volume dosage even of nonlubricating liquids or at high pressures. Driven by a high-power DC-servomotor the pump allows dosage in a broad viscosity range and shows small, economic dimensions. The mzr-7208 targets applications in industrial production and process technology. The pump has been designed for continuous delivery and discrete dosage of water, watery solutions, solvents, methanol, oil, lubricants, adhesives, inks and paints as well as other high viscosity liquids. Applications - Chemical processing - Industrial and plant engineering - Packaging - Medical and pharmaceutical industry - Mini plant technology - Spraying - Dispensing of adhesives - Ink and paint dosage - Vacuum applications Even if single parameters are within the indicated performance range of technical data, certain parameter combinations may not be achievable. Single parameters may exceed their indicated performance range under adequate circumstances. For detailed evaluation please contact HNP Mikrosysteme. Actual performance may vary. Specifications are subject to change without notice.
