HNPM Micro pumps

Micro gear pumps for pulseless pumping very small volumes, also non-lubricating and inert fluids. For high pressure, low pressure and OEM applications. Hermetically sealed micro pumps ensure safe pumping of crystallizing, oxygen- and moisture sensitive fluids.
Highly precise metering volumes in microliter to millilitre range and smallest volumetric flows, also for non-lubricating and inert fluids.

The use of HNPM micro pumps

HNPM micro pumps are typically used for pulseless and precise dosing and metering small amounts of low or highly viscous liquids. Thanks to their high process stability, the micro annular gear pumps make this new dimension in metering technology available to a wide range of applications. Hermetic pumps (leak-free!) and pumps for EX zones are also available.
Do you have special requirements? Customized modifications are optional!

Fluidic technology accessories such as connectors, adaptors, sensor technology products and filters are available to complete the scope of supply.
