Grundfos SBA 3-45

Grundfos SBA 3-45 submersible pump for clean water,  and general lifting duties. With in-built electronics for fully automatic on-demand use and run-dry protection. The pump has an integrated strainer and 1″ outlet and is fitted with 15m of cable.

The Grundfos SBA 3-4  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. It comes with an integrated control unit eliminating the need for an external pump controller. With SBA it is literally a matter of “plug and pump”. Once the pump is installed and connected to the piping, all you need to do is switch it on. The result is a reliable solution and greatly reduced installation costs. The pump is available in two main versions:

• with integrated suction strainer (1 mm mesh)
• with side inlet/flexible suction hose with floating suction strainer (1 mm mesh).

Both variants are available with or without float switch.
The float switch offers stop at low water level, preventing surface fragments from entering the strainer.

The new Grundfos SBA 3-45  is a complete all-in-one unit. It is built on the proven SB platform, but comes with an integrated control unit – eliminating the need for an external pump controller.

The SBA is literally a plug- and pump solution. Once installed and connected to the piping, all you need to do is switch on the pump.

Floating suction strainer
The Grundfos SBA 3-45 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 Grundfos SBA3-45  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
