  • Compact and designed to last
    The high quality components and the design of the Hydro Multi-B booster system have been chosen with a focus on sturdiness and compactness. As a result, the user gets the benefits of a complete solution, with components optimized for domestic water pressure boosting.
  • Reliability
    The CM pump has high reliability built-in. Clamping of the pumps impeller has been greatly improved by implementing a new stop ring to form a well-defined base.
    Combining this feature with a Nordlock© washer at the other end of the pump stack creates a robust and reliable design.
  • Ready… Set… Pump!
    Before leaving the factory, every unit is completely assembled and thoroughly tested and inspected. This means that when customers receive their Multi-B booster system, it is only a matter of plugging it in and starting it up.
  • Large complexes such as schools and office buildings
  • Multi-storey buildings
  • When redundant pumping is needed
