GRUNDFOS SB3-35A Multistage Sub Pump


the Grundfos SB 3-35 A is a submersible pump designed for clean water pumping, particularly for domestic and rainwater applications. 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 which are resistant to corrosion.

The SB 3-35 A is equipped with a 15 metre 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.
This pump is ideal for operation in a well or ground tanks as it easily prevents solid particles from entering the pump, the maximum particle size being 1mm.
Featuring a float switch, this promises the user a convenient experience with automatic start/stop operation of the pump and provides dry running protection.
The single-phase pump model is effectively protected against any accidental overload by built-in thermal protection, meaning the pump immediately stops if it overheats.
After cooling down, the pump automatically restarts when it reaches a normal temperature.


  •  Silent alternative to surface pumps
  •  Built in thermal overload protection
  •  Float switch option used for automatic operation or dry running protection of the pump
