Modular pump series mzr-7242


Fluid-dependent customizable dosing pump The micro annular gear pump mzr-7242 of the modular pump series is suitable for dosing and metering in low to medium pressure and viscosity ranges. To the main assets of this series belong low pulsation, high precision low volume dosage of non-lubricating liquids, compact design with smallest dimensions and low price. These pumps are suitable for dosing and dispensing deionized water, aqueous solutions, solvents as well as low to highly viscous oils, lubricants or dyes. Advantages Compact dimensions length 132 mm High dosage precision precision CV 1 % at low volumes Small dosage volumes, high flow rates smallest volume 30 µl, flow up to 288 ml/min Long service life wear-resistant tungsten carbide Low pulsation delivery, low shear stress rotary micro annular gear technology Applications Analytical instrumentation Fuel cells Biotechnology Laboratory automation In vitro diagnostics
