Grundfos SCALA1 is an all-in-one pressure boosting unit with a high-efficiency motor and hydraulics with low noise operation for domestic water supply and also light commercial applications.

Built-in Bluetooth communication gives you complete control over the pump using the Grundfos GO REMOTE, also for twin pump operation.

This means that installation and commissioning has never been easier. The Grundfos GO REMOTE app also lets you see alarm status and get easy pump diagnostics.
You can create and email reports onsite and access hard-to-reach installations remotely from the app.

EASY TWIN PUMP CONTROL
Built-in multi-pump/booster technology enables twin pump connection with joint pump control in either duty/assist or duty/standby mode.

Online configuration is done easily using the Grundfos GO REMOTE app, where you can also adjust the alternation setup.
