precise pumps – smart solutions


HNP Mikrosysteme develops, manufactures and markets pumps worldwide which dose small amounts of liquids fast and accurately. Micro annular gear pumps (mzr®-pumps) make conventional applications more effective and open new technology fields.


Started in 1998 by a team of 5, the company now counts more than 80 employees and is situated in the North of Germany. In addition to construction, development, quality assurance, assembly and technical service, they have a specialized technical sales team consisting of engineers and scientists.


Application possibilities are in the field of life science and analytical instrumentation, at mechanical and plant engineering as well as chemical and pharmaceutical process engineering. Furthermore, HNPM develops dosing systems according to customer requirements.


Short description of micro annular gear pumps


                              Five different series provide a wide range of applications


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 viscous liquids. With different equipment, dosing volumes starting at 0.25 µl, flow rates ranging from 1 µl/h to 1.1 l/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.


Special features are distinguished by low pulsation, low shear stress, low dead volume, long service life, low weight and a compact structure as well as wear and corrosion resistant materials.


A detailed overview of performance data includes the flow rate range and minimal dosage, the differential pressure as well as the viscosity range for individual pumps - link to download Micro annular gear pump technical data
