The SB and SBA pump is a submersible booster pump for the pumping of clean water. It is especially suitable for rainwater applications and private wells. The pump is available in two versions:

SB

The Grundfos SB is a submersible pump for the pumping of clean water. It is designed for use in domestic applications. The pump itself is very silent, and when installed underground in a rainwater collecting tank or well, noise will never become an issue. The SB pump requires an external controller, like Pressure Manager, for automatic operation.

Features and benefits

• Flexible selection – Pump + controller
• Complete control and monitoring
• Easily accessible controller – for service & replacement

SBA

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.

Features and benefits

• Easy selection – one unit
• Easy installation – one unit
• Flexible installation – no controller inside the house

All SB and SBA pumps are available in two main variants

• With integrated suction strainer (1 mm mesh)
• Or with side inlet/flexible suction hose with floating suction strainer (1 mm mesh).

All variants are available with or without float switch:

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