The low-noise Grundfos SCALA2 domestic booster pump offers homeowners constant water pressure, regardless of municipal inlet pressure and multiple open taps. Fully integrated, the new self-priming pump is designed to boost water pressure from city mains, shallow wells and storage tanks, serving residential buildings with up to three floors and eight taps. A pump control sensor compares measured and desired water pressures, adjusting pump speed accordingly and ensuring a perfect water pressure through the system, Grundfos states. The plug-and-pump solution has a user-friendly control panel to enable manual pressure adjustments.
