The Grundfos SCALA2 3-45 is an all-in-one, self-priming water booster that delivers perfect constant water pressure in homes with up to 3 floors and 8 taps. Pump, permanent-magnet motor, pressure tank, sensors, variable-speed drive and non-return valve are built into one compact, water-cooled unit — at 47 dB(A) it is one of the quietest boosters on the market. Intelligent speed control measures pressure on both the inlet and outlet side and adapts continuously, so the shower stays steady even when other taps open.
Typical applications
- Boosting city water pressure in single-family homes
- Drawing from rooftop or break tanks and shallow wells (self-priming)
- Rainwater harvesting systems
