Scala1 is a modern domestic waterworks providing constant water pressure at all tapping points. Compact self-priming domestic water station with integrated control unit for automatic operation, pressure vessel and built-in non-return valve.

Why choose SCALA1?

SCALA 1 is a compact waterworks - all in one. The pump is equipped with an integrated control unit and a pressure relief vessel. When the pressure in the supply line drops, the pump switches on and constantly supplies flow and pressure to the water distribution in the house. When the tap is closed, SCALA1 recognizes the flow stop and switches off the pumping. Thanks to the integrated buffer tank, it ensures constant pressure.

Smart features

Thanks to the built-in Bluetooth wireless interface, the device can be connected directly to a mobile phone and have access to advanced pump settings. For example, for home irrigation systems, a programmable timer function may be useful.


With the SCALA1, you get constant water pressure in all water taps, no matter how many of them are flowing.


SCALA1 provides trouble-free operation and has been thoroughly tested in a variety of conditions. It offers maximum reliability in a wide range of applications.

Power curve

What is the difference between Grundfos SCALA pumps?


Scala1 is a modern domestic waterworks providing constant water pressure at all tapping points. It ensures constant pressure by means of a pressure and flow control unit in combination with an integrated pressure vessel.


Scala2 is equipped with a built-in pressure sensor that measures continuously. If the pressure value falls below the required level, SCALA 2 immediately increases the output and thus compensates for the pressure losses. Pressure changes are immediately transmitted to the pump speed change thanks to the built-in frequency converter.
