HNP MIKROSYSTEME

HNP Mikrosysteme develops, manufactures and markets pumps worldwide. These micro annular gear pumps (mzr® pumps) are ideally used where fast, reliable and highly precise dosage is required. They are characterized by pulseless delivery, low shear stress, minimal dead volume, long service life, small dimensions, highly resistant materials and ease of maintenance.
Whether in research or in production, mzr® pumps are used to handle small amounts of liquids of very different nature or texture, slightly or highly viscous, gentle or aggressive, lubricating or not, at low to high temperatures and pressures.
HNPM's solutions are perfectly suited to complex and demanding tasks in cosmetics, fine chemistry, pharma, engineering and life science.

Robust and reliable, our micropumps are present on the International Space Station, contributing to advances in microfluidics.

Micro annular gear pumps are miniaturized rotary positive displacement pumps. The micro annular gear pump product range consists of five different series of mzr® pumps for dosing and metering small amounts of low to high viscosity liquids.
With different equipment, dosing volumes starting at 0.25 microliter, flow rates ranging from 1microliter/h to 1.1liter/min as well as pressures from 0 to a maximum of 150 bar are possible. The range of the liquid viscosity extends from 0.3 to 1,000,000 mPas.
Operation in an explosion-proof area is also possible. HNP Mikrosysteme offers the development of OEM pumps, comprehensive application-specific consulting, technical support and training.
