The Grundfos SB 3-35 A is a submersible multistage booster pump for domestic water applications, including rainwater harvesting and pressure boosting. Unlike the SBA series, the SB requires an external control unit such as the Grundfos Pressure Manager for complete pump control. Silent in operation when submerged, the pump is a noiseless alternative to surface-mounted systems.
The SB 3-35 A is ideal for wells or ground tanks. It prevents solid particles from entering the pump (maximum particle size 1 mm) and is built from high-quality composite and stainless steel, making it corrosion-resistant and durable. Built-in thermal protection ensures safe operation by stopping the pump if it overheats and restarting it automatically once cooled.
