Grundfos Pump SBA 3-45 A - Submersible Pump with float
Grundfos SB 3-45 A is a submersible pump designed for the pumping of clean water for domestic and rainwater applications. It is silent (25 dB max - comparable to a person whispering) when submerged and therefore a noiseless alternative to surface-mounted pumps. The pump is built from high quality composite and stainless steel materials that are resistant to corrosion.
The SB 3-45 A is equipped with a 13.7 m supply cable, and the maximum installation depth is 10 m below the water level, with a liquid temperature ranging from 0 °C to 40 °C.
The SB 3-45 A is ideal for operation in a well or ground 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 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.
