The BMS range is a new range of booster modules for reverse osmosis and ultra-filtration applications that improve efficiency with a directly coupled pump powered by a permanent magnet motor and VFD.

The BMS range comes in 3 different combinations:

  • BMS hs: High pressure booster system
  • BMST: High pressure booster system with energy recovery via turbine
  • BMSX: High pressure booster system with energy recovery via pressure exchanger

Technical data:

  • All wet end components are super duplex and 904L stainless steel suitable for use in seawater and brackish water applications
  • The shaft seal is made from carbon/silicon carbide, especially designed for high pressure
  • The thrust bearing material is ceramic and carbon
  • Pump bearings and seal rings are made of NBR rubber
  • Built-in thrust bearing absorbing the axial thrust from the pump


  • Reverse Osmosis systems
  • Ultra filtration system
  • Filtration systems
  • Pressure boosting systems and water supply

Features & Benefits:

  • Energy savings due to high efficiency
  • Easy maintenance and alignment due to improved design
  • Easy integration in any water treatment system
  • Extreme durability and reliability
  • Very small footprint
  • Designed for high flows and pressure
  • All critical components in contact with water are made of super duplex stainless steel
  • Speed ramp up and down are included
  • VFD pre-set at duty point.
