Micro annular gear pump HNPM mzr-4605
Pump for industrial production and process technology
The micro annular gear pump mzr-4605 covers the flow rate range 0.012-72 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, compact design and an integrated microcontroller. The pump allows dosage in a broad viscosity range and shows small, economic dimensions. The mzr-4605 targets applications in industrial production and process technology. The pump has been designed for continuous delivery and discrete dosage of water, watery solutions, solvents, ethanol, oil, lubricants, adhesives, inks and paints as well as other high viscosity liquids.
