Grundfos SCALA2 3-45 115V Water Booster Pump

Grundfos SCALA2 3-45 (product no. 98562818) is a fully-integrated, self-priming domestic pressure-boosting pump that keeps water pressure constant throughout the home—even with multiple taps running. The unit combines pump, motor, intelligent controller, variable-speed drive, pressure sensor, expansion tank and non-return valve in one compact, quiet package (as low as < 47 dB(A) in typical use). It auto-adjusts performance to inlet pressure and demand, installs quickly, and includes dry-run protection for reliable operation.
