Grundfos Scala2 3-45
Grundfos Scala2 3-45 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 the pump, motor, tank, sensor, drive, and non-return valve into one compact unit. And with its intelligent pump control, Grundfos 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. Grundfos Scala2 3-45 features a built-in sensor, which constantly measures the discharge pressure. If the pressure drops below the desired level, Scala2 boosts its operation immediately to compensate for the loss of pressure. We call it intelligent pump control, resulting in perfect water pressure.
