Alpha2 circulating pump

ALPHA2 circulating pump, the new circulating pump that is more efficient and reliable than ever, as well as versatile.

Grundfos offers the best energy efficiency on the market with its wide range of control modes and simple, precise hydraulically assisted balancing. The ALPHA2 circulator system/kit consists of an ALPHA2 pump, the ALPHA Reader, and the Grundfos GO Balance app.

Together, they allow for extremely precise and easy hydronic balancing of a two-pipe radiator or underfloor heating system. GO Balance will guide you through every step of the process and provide documentation, saving you valuable time. ALPHA2 also offers long-lasting reliability even in the most demanding systems.

Alpha Reader for the ALPHA2 Circulator Pump

The ALPHA Reader is a small, pocket-sized accessory that attaches to the front of the ALPHA 2 circulator. It reads the pump signal and communicates with the GO Balance system balancing app via Bluetooth during the balancing process. Once the hydraulic balancing is complete, the installer can remove the reader from the front of the pump and take it with them to the next job.

Grundfos Go balance app for balancing ALPHA2 circulator pump systems

The Grundfos Go Balance app can be downloaded free of charge from iTunes or Google Play. The app receives the Bluetooth signal from the ALPHA Reader and guides the installer through the entire balancing process in a few simple steps.

GO Balance is the first mobile platform for hydraulic balancing of underfloor and two-pipe heating systems, which also provides technical documentation, issues reports, and saves time and energy.
