Grundfos SB3-45A 230 V Submersible Pump with Float Switch

The Grundfos SB 3-45 A is a multistage submersible booster pump for domestic rainwater harvesting and water-pressure boosting. It draws through an integral strainer and includes a float switch for low-water protection.

Unlike the SBA range, the SB pump requires a separate controller such as a compatible Grundfos PM1 or PM2 Pressure Manager for automatic pressure control.
