SBA 3-45 A submersible pump

SBA 3-45 A from Grundfos is an all-in-one submersible booster set designed to pump clean water for domestic use.

The SBA is built on the proven SB platform and features an integrated control unit. This eliminates the need for an external pump controller in the house.

It makes no noise when submerged and is therefore a silent alternative to surface mounted pumps. The pump is made of high quality composite and corrosion resistant stainless steel materials.

The SBA 3-45 A is equipped with a 15 m supply cable, and the maximum installation depth is 10 m below the water level, with a liquid temperature between 0 °C and 40°C.

The pump starts automatically when the pipe pressure drops below 2.2 bar. The SBA 3-45 A is ideal for operation in wells or surface tanks, as it easily prevents solid particles from entering the pump. The maximum particle size is 1 mm.

The single-phase model is effectively protected against any accidental overload by means of integrated thermal protection. The pump has built-in thermal protection, which immediately stops the pump if it overheats. After having cooled down, the pump restarts automatically when it reaches a normal temperature.
