Magnetically-driven micro annular gear pump is ultra-compact
Michael Smith Engineers is introducing the ultra-compact HNP MZR 4661 pump, a magnetically-driven micro annular gear pump that is suitable for handling liquids in critical metering applications where reliable, leak-free pumping is essential. This new pump is designed for OEMs and small system builders who require a pump to deliver precise, pulseless flows from 4.8 to 72ml/min on system pressures up to 6bar.
The pump benefits from a hermetic design incorporating a powerful inner magnet system that is driven by a rotating magnetic field and an integrated speed control. However, the pump is very compact, with a diameter of just 22mm, a length of 69mm and a weight of only 100g. Although compact and lightweight the MZR 4661 is built to ensure a long service life thanks to the use of wear-resistant, ultra-hard materials including stainless steel, ceramics and NdFeB magnets.
Fuel cell operations are one particular application where these pumps will be appreciated, for metering water, ethanol, methanol and other fuels. Other applications include Ad-Blue injection into catalytic converters for diesel engines to reduce emissions, and also dialysis and other similar medical device applications
