Grundfos SBA 3-45 AW Pumps

Notify me when this product is available:

The Grundfos SBA pump is perfect for rainwater harvesting because of the dependable design and simple plug-n-play installation.  This allows rainwater to be a reliable source of water for residential or commercial applications.  The SBA was built with the customer in mind hence by the noiseless operation to not disturb.  This pump comes with an integrated control unit eliminating the need for an external pump controller.

This unit is constructed from composite and stainless-steel materials and making the unit resistant to corrosion.  The stainless-steel suction filter with 1,000-micron (0.039 in) mesh is made from stainless steel and ensures only the cleanest water is drawn, leaving the floating particles on the surface.  

The included float switch allows a longer life by preventing the pump to run when water is not available, not allowing air to enter the unit.  In turn, once water is present, the pump automatically restarts. 

Built-in thermal protections ensure the SBA pump will never overheat and automatically restarts once normal temperatures are reached. 


  • Simplicity – all-in-one unit
  • Easy installation – no external control unit
  • Integrated dry-running protection
  • Automatic restart after dry-running
  • Lifting eye makes for easy transport
