Grundfos SCALA2 is fully integrated, self-priming, compact water pump for pressure boosting in domestic applications. SCALA2 incorporates integrated speed control, enabling perfect pressure at the taps, meaning that the pump performance automatically adjusts according to demand.

Grundfos SCALA2 has all the components necessary to ensure comfortable pressure:

• intelligent controller

• integrated variable-speed drive

• integrated tank

• integrated sensors

• integrated inlet and outlet valves.

SCALA2 features self-priming, which enables the pump to extract water from a level below the pump. Once adequately primed, the pump is capable of effortlessly lifting water from depths down to 8 metres in less than 5 minutes. The pump moreover guarantees reliable water supply in situations where there is a risk of dry running and leakages in the inlet hose or pipes, thereby enhancing the overall reliability of the system.

In the event of dry running, water shortage, extreme temperatures or if the pump becomes blocked due to seizure or overload, the pump automatically shuts down, preventing damage or motor burnout.

Thanks to its hydraulic design, permanent-magnet motor and water cooling, the pump is extremely low-noise, 44 dB(A) in typical use, which makes it suitable for indoor as well as outdoor use. Maximum noise level at full load is 53 dB(A).

The built-in pressure tank reduces the number of starts and stops in case of leakages in the pipe system, thereby prolonging the life of the pump.
