Product details

The Grundfos Alpha 2 is a highly efficient circulating pump specifically designed for heating applications. It utilizes a permanent magnet motor with ECM technology, allowing for electronic power adjustment. This is achieved through stepless speed variation, ensuring optimal adaptation to the respective operating conditions. The pump is equipped with an AutoAdapt function that automatically selects the most efficient operating mode, as well as a night setback function that reduces energy consumption during periods of low demand. With a maximum head of 4 meters and a flow rate of up to 1.5 m³/h, the Alpha 2 is suitable for various heating applications. The pump is robustly constructed and offers high energy efficiency with an energy efficiency index (EEI) of 0.15. It is designed for continuous operation at temperatures ranging from 2 to 110 degrees Celsius and meets the requirements of insulation class F according to IEC.

  • Energy efficiency index (EEI) of 0.15 for low energy consumption
  • AutoAdapt function for automatic adjustment of operating mode
  • Night setback function to reduce energy consumption
