Grundfos SBA 3-45 A Submersible Pump

2 Year Standard Warranty

Grundfos SBA 3-45 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 3-45 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 3-45 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.

The Grundfos SBA is a compact, submersible booster pump with
integrated pressure switch designed for the delivery of clean
rainwater into the home.

• Easy submerged installation – plug & pump – Connect the
  pump outlet to the pipework, plug into a power outlet and
  you’re ready to pump
• Automated control and ongoing protection – An integrated
  pressure switch and float switch provide pump control and
  protective features.
• Virtually silent submerged operation – Won’t disturb your
  family or neighbours
• For water sources above or below ground – Designed to be
  submerged in either above ground water tanks or below
  ground water sources
