Grundfos SCALA2 series water booster pumps are designed to to provide constant water pressure in all taps at all times, even when multiple taps are running at the same time. SCALA2 pumps are perfect for residential buildings with up to 3 floors and 8 taps. These advanced Grundfos pumps are also commonly found pressure boosting city main water, water from roof tanks, break tanks and ground tanks, as well as supplying water from shallow wells up to 8 meters deep. The SCALA2 is compact and easy to install in a variety of configurations. It operates quietly at a sound level of only 47 dB(A) during typical use. An intelligent pump control system ensures that the user can designate his or her ideal water pressure. An integrated sensor detects if the inlet pressure varies or if multiple taps are running water and relays that communication to the booster pump. The Grundfos SCALA2 is a convenient all-in-one unit that includes the pump, motor, tank, sensor, drive and non-return valve.
