GRUNDFOS ALPHA2 is the new generation of small circulation pumps in the highest energy class "A". The ALPHA2 circulation pump is the youngest and most innovative member of the family of high-quality Grundfos circulation pumps. These pumps are used for circulating water in heating systems and hot water systems.

The pump's performance makes it suitable for both heating and hot water circulation in commercial buildings, as well as in households and family homes. It can also handle heating in industrial buildings.

The circulation pump meets the requirements of the EuP directive.

Performance Range

AUTOADAPT Function

Each pump setting corresponds to a specific performance curve. However, with the ALPHA2 pump, there are no worries about complicated adjustments and settings. If you leave the factory setting on the AUTOADAPT function, the pump will automatically analyze the given heating system, find the optimal setting, and adjust according to the requirements and changes in heat demand. It thus covers a certain performance range including several performance curves, from which it selects the most optimal option. A more detailed description of the AUTOADAPT function can be found in the attached data sheet. The AUTOADAPT function can be disabled by selecting another mode (according to proportional or constant pressure or classic three-speed operation).

Applications

• Single-pipe or double-pipe systems with radiators.
• Underfloor heating.
