The MZR Magnetic Hermetic Series of micro-annular internal gear pumps from HNP Mikrosysteme are ideally suited to handling liquids in critical metering applications where reliable, leak-free pumping is essential.  This pump range is designed for OEM's and small system builders who require a pump to deliver precise, pulseless flows from 4.8 ml/min up to 72 ml/min at differential pressures up to 5 bar.

The Magnetic Hermetic Series benefits from a leak free hermetic design incorporating a powerful inner magnet system 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 weighs just 100g.  Although compact and lightweight, the MZR4661 is built to ensure a long service thanks to the use of wear resistant, ultra hard materials, including stainless steel and ceramics.

Fuel cell operations are one particular application where these pumps will be appreciated, on metering tasks for water, ethanol, methanol and other fuels occurring in these industries.  Other applications include AD-Blue injection into catalytic converters for diesel engines to reduce emissions and also dialysis and other similar medical device applications.  Any application where avoidance of leakage is an important criterion, this new pump can be used and prove its superiority with it’s long service life.
