Grundfos Alpha2 GO 25-40 (130) Domestic Heating Circulator 240v - 93074270
The Grundfos ALPHA2 GO 25-40 130 is a high-efficiency circulator pump designed for use in domestic heating and air conditioning systems. Equipped with an electronically commutated motor, it offers four intelligent control modes - constant pressure, proportional pressure, constant flow, and constant curve - making it easy to match the pump’s performance to your system’s needs.
Installation is fast and straightforward thanks to the included toolless installer plug. Quiet and reliable operation is supported by dry-running protection, self-venting, and a robust startup system that helps prevent blockages from dirt, limescale, or magnetite. The ceramic shaft and bearings further enhance long-term durability by reducing internal wear.
Fully compatible with the Grundfos GO app, this pump simplifies replacements and new installations alike.
Its AUTOADAPT feature automatically selects the most energy-efficient setting in constant and proportional pressure modes, reducing setup time and improving efficiency for radiator and underfloor heating systems. A built-in digital display provides real-time information on flow rate, head, and power consumption, helping installers optimise performance and troubleshoot with confidence.
Backed by a 5-year manufacturer's guarantee, the ALPHA2 GO is a reliable, energy-conscious solution for modern heating systems.
