The Grundfos SCALA1 is a self-priming, multi-stage 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 min. This facilitates easy installation and start-up of the pump and provides more reliable water supply in installations where there is a risk of dry running and leakages in suction hose 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.

  • Cycling protection which will prevent pump starting frequently in case of minor leakages in installation
  • Max runtime protection can stop the pump after a desired period of continuous operation, preventing potential damage due flooding in case of pipe breakages
