SCALA1 5-55 (110V or 220V)
Product number 99631754
(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.)
- Plumbing: Pressure Boosting
- Residential groundwater intake
- Residential water pressure boosting
- Residential rainwater harvesting
The Grundfos SCALA1 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. 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.
