Grundfos website states that the"SCALA2 is a fully integrated water booster pump providing perfect water pressure in all taps at all times - even with multiple taps and showers running at the same time. It packs pump, motor, tank, sensor, drive and non-return valve into one compact unit. And with its intelligent pump control, SCALA2 automatically adjusts performance to both inlet pressure and water consumption in the home. Thanks to a water-cooled motor, SCALA2 even offers one of the lowest noise levels of any booster on the market." SCALA2 features a built-in sensor, which constantly measures the output pressure. If the pressure drops below the desired level, SCALA2 boosts its operation immediately to compensate for the loss of pressure. Grundfos calls it intelligent pump control and the result is exact water pressure.
