ALPHA2 offers increased comfort and efficiency

If you are concerned about reliability, the ALPHA2 canned rotor circulator pump takes reliability in small domestic circulators to new heights. Even in systems where the operational environment is a challenge, the ALPHA2 will ensure long-lasting trouble-free operation with reduced risk of blockage. Although small in size, the ALPHA2 is the toughest domestic circulator around and is perfect for domestic buildings.

The ALPHA2 offers easy hydronic balancing using the ALPHA READER and GO BALANCE app, less blocking and best-in-class energy efficiency. AUTOADAPT automatically adjusts the pump to system demands for optimum comfort and lowest energy consumption. This adds up to a robust pump offering unrivalled energy-efficiency and easy installation that covers both your heating demands and most of your air-conditioning and demands.

Easy hydronic balancing from your smartphone

From the moment the circulator is installed and connected via the ALPHA READER, you are guided quickly and easily through every step of flow-based hydronic balancing in the Grundfos GO BALANCE app.

Robust start-up: if the rotor is blocked, the pump automatically attempts a restart, swiftly breaking up any deposits of dirt or lime – without external interference.

Dry-running protection during start-up and normal operation makes sure the pump will never run without liquid in the system.

AUTOADAPT automatically finds the best pump setting to maximise comfort and minimise energy consumption in Radiator, Underfloor, and Radiator + underfloor modes, or use incremental set point adjustment with user-specific control modes for Constant pressure, Proportional pressure and Constant curve.
