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. Suitable for: Plumbing: Pressure Boosting, Residential groundwater intake, Residential water pressure boosting, and Residential rainwater harvesting. The Grundfos SCALA1 3-45 is a self-priming, multistage pump, that incorporates all the components of a pressure booster into a compact composite enclosure. As it is self-priming, the SCALA1 can pump water from a level below the pump. Provided it is filled with water, the pump can lift water from a depth of 8 m in less than 5 minutes. This facilitates easy installation and start-up of the pump and provides a more reliable water supply in installations where there is a risk of dry running and leakages in suction hoses or pipes.
SCALA1 can communicate with Grundfos GO app via built-in Bluetooth, which enables detailed pump monitoring and high customization options, making this pump a good fit for every application. SCALA1 incorporates advanced protection features such as: Dry running protection that will automatically stop the pump in case of water shortage, Cycling protection which will prevent the pump from starting frequently in case of minor leakages in installation, and max runtime protection can stop the pump after the desired period of continuous operation, preventing potential damage due to flooding in case of pipe breakages.
The pump has built-in motor protection that will stop the pump if exposed to excessive temperature due to high ambient temperature, in case of seizure or overload, thus preventing a motor burnout. With Grundfos GO you can easily set up SCALA1 as a Twin booster system, operating as duty/stand by as well as duty/assist. It is also possible to add external input control and schedule a pump operation via the calendar function. SCALA1 requires no maintenance, but it is recommended to keep the pump clean, check the non-return valves and keep the ventilation holes free of dust.
