The domestic water pump Grundfos Scala2 is a compact, versatile solution for indoor and outdoor water supply. Thanks to constant pressure control, it does not need a membrane pressure vessel and requires only a quarter of the usual space. The water-cooled permanent magnet motor provides the same hydraulic performance as a traditional domestic water pump. It is very quiet and extremely energy-efficient with a maximum of 550 watts of power input. Scala2 can be installed without tools in no time and features ten safety and comfort functions for protection against dry-running or overvoltage/undervoltage.
