    The Grundfos 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, the SCALA2 automatically adjusts performance to both inlet pressure and water consumption in the home. Thanks to a water-cooled motor, the SCALA2 even offers one of the lowest noise levels of any booster on the market.

    The SCALA2 features a built-in sensor, which constantly measures the discharge pressure. If the pressure drops below the desired level, the SCALA2 boosts its operation immediately to compensate for the loss of pressure. We call it intelligent pump control and the result is perfect water pressure.

    • Low noise:As quiet as a modern dishwasher (47 dB(A) in typical use)
