Description SBA 3-35 A Grundfos SBA 3-35 A 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 is built from high quality composite and stainless steel materials that are resistant to corrosion. The SBA 3-35 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 ranging from 0 °C to 40 °C. The pump starts automatically when the pipe pressure falls below 2.2 bar. The SBA 3-35 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 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 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.
