Integrated protection the pump offers thermal overload protection.

Simplicity all-in-one unit

Easy installation

no external control unit

 Integrated dry-running protection

 Automatic restart after dry-running


The new Grundfos SBA 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.

With the new SBA, everything you need to guarantee reliable pumping of water is included.

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.

The result is a reliable solution and greatly reduced installation

Aqua saver will automatically start when the demand is sensed - for example, when flushing the toilet or filling the washing machine - and will switch over to mains water when your tank is empty

The pump is only activated when the rainwater is being drawn from the tank. 

Grundfos has incorporated a specially designed valve eliminating the need for an in-tank float, drastically decreasing installation time. 

Grundfos pumps comply with AS/NZS 4020 testing of products in contact with drinking water.


Grundfos SB3A  range offers a reliable solution to help you utilise your collected rainwater in the best possible way with added mains water back up.
