The Grundfos ALPHA2 GO 25-40 130 220–240V is a high-performance, energy-efficient circulator pump designed for heating systems in both residential and light commercial applications. Engineered with advanced control functionality, it ensures optimal system performance while minimising energy consumption.

The integrated AUTOADAPT function automatically adjusts pump operation to match system demand, improving efficiency and maintaining consistent comfort levels. The pump also features three control modes—proportional pressure, constant pressure, and constant curve—each with three adjustable settings for precise system optimisation. A built-in user interface provides real-time feedback, displaying energy consumption (W), flow rate (m³/h), and system alerts for easy monitoring and diagnostics. The maintenance-free design incorporates a canned rotor and robust internal components for long-term reliability. Compatibility with the Grundfos GO Balance app and ALPHA Reader allows for fast and accurate hydraulic balancing, improving system efficiency without added complexity.
