Grundfos BMS
Booster Module Pumps

Grundfos BMS hs
Grundfos BMST
Grundfos BMSX

The Grundfos BMS range is a completely new range of booster modules
mainly used for reverse osmosis, filtration and ultrafiltration applications
that improve efficiency compared to earlier ranges.

It features a directly coupled pump powered by a permanent magnet motor
and Variable Frequency Drive (VFD).

The Grundfos BMS range comes in 3 different combinations:
 

  • ✔︎ Grundfos BMS hs
    High pressure booster system.
  • ✔︎ Grundfos BMST
    High pressure booster system with energy recovery via turbine.
    Pressure booster module & energy recovery system with pressure exchanger.
    Grundfos BMST booster systems consist of a Grundfos BMS hs pump and a Pelton turbine.
    This provides the same capacity as a standard centrifugal pump,
    and thus save up to 35% on the total energy consumption of the pump.
    Grundfos BMST booster systems are suitable for desalination plants.
  • ✔︎ Grundfos BMSX
    High pressure booster system with energy recovery via pressure exchanger.
    The Grundfos BMSX booster system is designed for desalination of seawater and brackish water.
    The BMSX system consists of a Grundfos BMS hs pump and a BMS hp pump
    and an isolatable pressure exchanger with an efficiency of up to 98 %.
    It can deliver 1500 m³ per day with an energy consumption of only 2 kWh per m³.
    produced water.
    The parts are made of Super Duplex stainless steel, polymer and ceramics,
    which makes the module extremely resistant to the working environment.
    It has a compact design and requires a very small installation area.
