Self-priming pressure group SCALA2 3-45 (New model)

The self-priming pressure boosting group SCALA2 3-45 from Grundfos, reference 93013252, is an ideal solution for those domestic applications where a constant increase in water supply pressure is required. This pump is specifically designed to ensure perfect pressure at taps, regardless of water demand, making it an ideal choice for underground water consumption, rainwater collection, and pressure boosting in the home.

SCALA2 is a fully integrated pump, which means it combines a pump, motor, tank, sensor, and check valve in a single compact unit. Its self-priming design allows for easy installation, even in situations where the pump needs to draw water from lower levels, such as wells or cisterns. This feature makes SCALA2 a versatile option for various domestic scenarios.

One of the main advantages of SCALA2 is its integrated speed controller. This technology allows the pump speed to be adjusted according to the home's pressure needs, ensuring a constant flow under all circumstances, from opening a single tap to when multiple consumption points are in use simultaneously. Additionally, its quiet operation ensures a comfortable home environment, even when running at full capacity.
