Grundfos SCALA1 3-35 - 99530409

Grundfos SCALA Databooklet

The Grundfos SCALA1 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 startup of the pump and provides more reliable water supply in installations where there is a risk of dry running and leakages in inlet hose or pipes.

SCALA1 can communicate with the Grundfos GO app via the built-in Bluetooth, which enables detailed pump monitoring and extensive customisation 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 leaks in the installation
• max runtime protection can stop the pump after a desired period of continuous operation, preventing potential damage due to flooding in case of pipe bursts.

The pump has a built-in motor protection that will stop the pump if it is exposed to excessive temperatures due to a high ambient temperature, in case of seizure or overload, thus preventing motor burnout.

With Grundfos GO you can easily set up SCALA1 as a twin booster system, operating as duty/standby as well as duty/assist. It is also possible to add external input control and schedule 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.
