The Grundfos SBA is an all in one submersible multistage pressure booster pump designed specifically for domestic water supply applications.
Unlike traditional above ground booster systems, the SBA is installed directly inside the water tank, making it virtually silent during operation. The integrated control unit automatically starts and stops the pump in response to water demand and includes built in dry run protection and thermal overload protection for long term reliability.
Constructed from corrosion resistant composite and stainless steel materials, the SBA is designed for continuous submerged operation in clean water. Stainless steel strainers prevent large particles from entering the pump, while optional floating suction kits allow clean water to be drawn from just below the surface where sediment is minimal.
The SBA is approved for use with drinking water and is ideally suited to rainwater harvesting systems supplying gardens, toilets, washing machines, and general household use.
Available with fixed or floating strainers and optional float switches, the SBA range can be configured to suit a wide range of tank and installation layouts.
