Grundfos SBA 3-45 AW is an all-in-one submersible booster designed for pumping clean water for domestic use. The SBA is built on the proven SB platform and comes with an integrated control unit. This eliminates the need for an external pump controller in the house. It is silent when submerged and therefore a noiseless alternative to surface-mounted pumps.
The pump features a float switch, which promises the user a convenient experience with automatic start/stop operation of the pump and provides dry running protection. The pump is equipped with a side inlet/flexible hose with floating suction strainer.
The single-phase model is effectively protected against any accidental overload by built-in thermal protection. The pump has built-in thermal protection, which immediately stops the pump if it overheats. Having cooled down, the pump automatically restarts when it reaches a normal temperature.
