SCALA1 5-55 (230V) 1.15HP - High Flow On-Demand Booster Pump

The Grundfos SCALA1 5-55 (230v) is a fully integrated, all-in-one, self-priming, compact waterworks designed for pressure boosting in domestic and light-commercial applications, such as garden irrigation or pressure boosting to one and two family houses and apartments. Suitable for:
-Plumbing: Pressure Boosting
-Residential groundwater intake
-Residential water pressure boosting
-Residential rainwater harvesting
-A small, 2 - 4 gallon pressure tank is recommended in applications where a water heater is in place to allow for thermal expansion in the line. A small pressure tank will also prevent cycling when a leak is present in the piping, extending the life of the pump.
-In city water or well water applications, use a PRLV-20, Pressure Reducing Limit Valve on the suction side of the pump to 20 PSI to prevent inbound water from exceeding the 29 PSI max inlet pressure.
-In applications where pump is near the home or point of use, it may be necessary to install a PRLV-60, Pressure Reducing Limit Valve on the discharge side of the pump to reduce the outlet pressure so as not to over-pressurize pipes during low flow usage.
