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.

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.

Model SBA-3-45 AW includes Floating Filter. Model SBA-3-45 A does not. Both Pumps include Float Switch.

Features and benefits:

  • 115V
  • 1 HP
  • Easy selection
  • Flexible installation
  • No controller inside the house
  • All SBA pumps are available in two main variants
  • With integrated suction strainer
  • Or with side inlet/flexible suction hose with floating suction strainer
  • Float Switch

The float switch offers automatic operation and dry run protection, stop at low water level, ensuring that surface fragments do not enter the strainer.

The SB and SBA pump is a submersible booster pump for the pumping of clean water. It is especially suitable for rainwater applications.

Although not required, a small, 2 - 4 gallon pressure tank is recommended to prevent cycling when a leak is present in the piping, extending the life of the pump. It also prevents the pump from starting/stopping when very little water is used, if a tap is only opened for a couple of seconds, for example.

 Product Reviews

  1. Excellent pump for cistern system

    Posted by Brad Schneider on 13th Oct 2016

    This pump is great because the controller etc is incorporated right into the pump. This made for a simple and clean installation in our new 1,500 gallon cistern, installed to provide water for my wife's gardens.

    I have it hooked up to a wall mounted hose reel and my wife loves it, she says it has excellent pressure and is so convenient. I would recommend this pump to anyone. Grundfos is a good name, and I expect it to serve us for a long time.

  2. SBA's Totally Reliable

    Posted by Bob Drew on 5th Jun 2015

    Our company has had its trials and tribulations with pumps and have installed many kinds. Controllers have also been an issue. We have now installed about 5 of these Grundfos pumps and knock on wood so far they are BOMB PROOF! Dare I say PLUG AND PLAY???
