Description
HNPM mzr-2505
Micro annular gear pumps are miniaturized rotary positive displacement pumps. They are based on a so-called micro annular gear principle with an externally toothed internal rotor and an internally toothed external rotor. The internal rotor has one tooth less than the external rotor, with tooth ratios of 6/7 and 10/11. The manufacturing tolerances of the rotors are in the range of few micrometers.
The micro annular gear pump mzr-2505 covers the flow rate range 0.0015-9 ml/min. The main features 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, compact dimensions. The mzr-2505 targets applications in industrial production and process technology. The pump has been designed for continuous delivery and discrete dosage of water, aqueous solutions, solvents, methanol, oil, lubricants, adhesives, inks and paints as well as other high viscosity liquids.
