ALPHA2 is the latest and most innovative member of the Grundfos family of high-quality circulators.


With ALPHA2, you can stop worrying about complicated pump settings. Simply install the pump and leave it in the factory setting, AUTOADAPT. ALPHA2 will automatically analyse the heating system, find the optimum setting and continue to adjust its operation to changes in demand.
