GRUNDFOS ALPHA2 is a new generation of small circulators in the highest energy class "A" . The ALPHA2 circulator is the youngest and most innovated member of the Grundfos family of high-quality circulators. The use of these pumps is to circulate water in heating systems and hot water systems.

Due to its output, the pump is suitable for heating and hot water circulation in commercial buildings, as well as in households and family houses. It can also handle heating of industrial buildings.

The circulation pump meets the requirements of the EuP directive.

Power range

AUTOADAPT function

Each pump setting corresponds to one power curve. However, in the case of the ALPHA2 pump, there is no need to worry about complicated adjustment and setting of the pump. If you leave the factory setting for the AUTOADAPT function, the pump will automatically analyze the heating system, find the optimal setting and adapt to the requirements and changes in the amount of heat. It thus protects a certain power range comprising several power curves, from which it selects the most optimal option. A more detailed description of the AUTOADAPT function can be found in the enclosed catalog sheet. The AUTOADAPT function can be deactivated by selecting another mode (according to proportional or constant pressure or classic three-speed operation).
