Submersible pump SB 3-45 A Grundfos

The SB 3-45 A is equipped with a 15m supply cable, and the maximum installation depth is 10m below the water level, with a liquid temperature between 0°C and 40°C. The SB 3-45 A is ideal for operation in wells or tanks on the surface, since it easily prevents solid particles from entering the pump. The maximum particle size is 1mm.

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

The single-phase model is effectively protected against any accidental overload by means of the 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.
