Grundfos SB submersible pump for clean water,  and general lifting duties. The pump has an integrated strainer and 1" outlet and is fitted with 15m of cable.

The Grundfos SB is a complete all-in-one submersible booster pump for pumping clean water. The pump is ideal for use in tanks or wells for water supply, irrigation, and specially suitable for rainwater applications and small private wells.

• with integrated suction strainer (1 mm mesh)

Both variants are available with a float switch.
The float switch offers stop at low water level, preventing surface fragments from entering the strainer.

 Features and benefits

  • Easy installation
  • Integrated dry-running protection
  • Automatic restart after dry-running
  • Lifting eye
Floating suction strainer
The SB model with floating suction strainer always draws the water from just below the water surface where the water is clean and free from solid particles.
Automatic restart
The SBA with float switch automatically restarts when water is added. The SBA without float switch will attempt to restart every 24 hours.
Overheat protection
Thanks to the built-in thermal protection, the pump stops immediately in case of overheating. Having cooled down, the pump automatically restarts when reaching normal temperature.
Longer life
The Grundfos float switch prevents air from entering the system as a result of dry running
