For industrial production and process technology

The micro annular gear pump mzr-7208X1 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 non-lubricating 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-7208X1 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.
