SCALA2-115V Grundfos (115V) Pressure Booster Pump (98562818) 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. .What is intelligent pump control? SCALA2 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.
