Micro annular gear pump mzr-7205 - 1

High performance series Micro annular gear pump mzr®-7205 For industrial production and process technology - High dosage precision precision CV < 1 % at low volumes - High differential pressures achievable even for low viscosity liquids - Compact dimensions length 155 mm, including controller - Broad viscosity range methanol, water, solvents, adhesives, grease, gel - Low pulsation delivery, low shear stress rotary micro annular gear technology - Long service life wear-resistant tungsten carbide - Precision motor and sophisticated control DC-servomotor with integrated microcontroller The micro annular gear pump mzr-7205 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 Applications - Chemical processing - Industrial and plant engineering - Packaging - Medical and pharmaceutical industry - Mini plant technology - Spray technology - 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. 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. pressures, compact design and an integrated microcontroller. The pump allows dosage in a broad viscosity range and shows small, economic dimensions. The mzr-7205 targets applications in industrial production and process Flow rate 0.048 - 288 ml/min Smallest dosage volume 30 pl Differential pressure range 0 - 30 bar (1 mPas); 0 - 40 bar (> 16 mPas) Max. inlet pressure 5 bar (73 psi); 10 bar * (145 psi *) Liquid temperature range -5 ... +60 °C (-20 ... +150 °C *) Viscosity range 0.3 - 50,000 mPas (1,000,000 mPas *) Dosage precision < 1 % Coefficient of Variation CV Fluid connection 1/8" NPT internal thread, lateral optional: 1/8" NPT internal thread, frontal Wetted parts stainless steel 316L (1.4404, 1.4435), tungsten carbide Ni-based; shaft seal: graphite-reinforced PTFE, stainless steel 316L; static seals: FPM, optional: EPDM, FFPM Motor DC-servomotor, 24 V DC, 44 W Controller integrated 16-bit microcontroller Interface 0-10 V, RS-232, 1 digital input/output Customized solutions on request. * with optional fluidic seal module, heat insulation module, heating module, gear box Contact HNP Mikrosysteme GmbH Bleicherufer 25 ■ D-19053 Schwerin e-mail info@hnp-mikrosysteme.de http://www.hnp-mikrosysteme.de
