The Grundfos UPS4 GO 25-65 130 is a high-efficiency circulator pump designed for domestic heating and air conditioning systems. Equipped with an electronically commutated motor, it offers intelligent performance through three selectable control modes—constant pressure, proportional pressure, and constant curve—each with three speed settings to suit a wide range of applications. Engineered for durability and reliability, the pump features a ceramic shaft and bearings to minimise wear and extend service life. It also includes automatic self-venting and dry-running protection, along with a robust startup function that helps prevent blockages caused by debris such as dirt, limescale, or magnetite. Full compatibility with the Grundfos GO app allows installers to quickly identify replacement settings via scan or search functions, while the integrated interface displays error codes for efficient diagnostics and maintenance.

Suitable for replacing both integrated UPS circulators and standalone pumps, the UPS4 GO delivers a practical and installer-friendly solution, backed by a 5-year guarantee.
