Self-Priming Pressure Booster SCALA2 3-45 (New Model)

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

SCALA2 is a fully integrated pump, which means it combines a pump, motor, tank, sensor, and non-return valve into 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 in all circumstances, from opening a single tap to when multiple consumption points are in use simultaneously. Additionally, its quiet operation ensures a comfortable domestic environment, even when operating at full capacity.
