The Grundfos SBA 3-45 AW is an automatic submersible multistage booster pump with a floating suction strainer. It is designed for domestic rainwater harvesting and water-pressure boosting where drawing water from near the surface can help avoid settled material at the bottom of a tank.

An integrated controller starts and stops the pump automatically, so a separate external pump controller is not required.
