BMP booster module piston pump

Grundfos BMP, piston pumps, are designed for the transfer of liquids under high pressure.

General Details


The pumps are based on the axial piston principle, enabling a very light and compact design.

The BMP is a positive displacement swashplate water pump. The pump is designed to handle industrial tap-water processes. Grundfos BMP pumps offer a total efficiency of up to 88 % and reduced pressure peaks due to the multiple piston design. They are an excellent choice wherever a reliable and compact pump is required for medium and high pressures.

BMP is available in three versions.

  • BMP for normal tap water
  • BMP-N for technical water/deionized water
  • BMP-R for sea water.


BMP pumps are suitable for a variety of applications ranging from the pumping of potable water to the pumping of chemicals. The pumps can be used in a wide variety of pumping systems where performance and pump materials must meet specific requirements.

Examples of applications:

  • Cleaning/washing
  • Injecting
  • Misting
  • Processing
  • Seawater desalination.
