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.

Advantages of HNPM micro pumps

  • Precise dosing
  • Low pulsation
  • Low shear stress
  • Self-priming
  • Low dead volume
  • Compact design
  • Long service life
  • Corrosion-resistant materials
  • Low weight
  • Suited for non-lubricating fluids
