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

The circulator meets the requirements of the EuP directive.

The pump shaft is made of ceramic, thus preventing the deposition of magnetic particles contained in the pumped liquid in the most critical parts of the pump.

Characteristics

AUTOADAPT Function

With the ALPHA2 pump, there is no need to worry about complicated adjustments and settings. If you leave the factory setting on the AUTOADAPT function, the pump will automatically analyse the given heating system, find the optimal setting, and adapt according to the requirements and changes in heat demand. A more detailed description of the AUTOADAPT function can be found in the attached catalogue 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.
