The new Grundfos UPS3 is a compact, high-efficiency replacement for Grundfos UPS and UPS2 15-50/60 circulator pumps and many internal boiler pumps. Built on a high-reliability platform proven in millions of boilers, the new Grundfos UPS3 improves on efficiency, head, diagnostics and fitting time. PLUS, clever design means on many boilers it can replace OEM internal pumps, saving time and money. Simply scan the old pump via the Grundfos GO Replace app to find out.

Suitable for domestic heating systems with boilers up to 30kW, just one model of UPS3 can be used to replace all previous 4m, 5m and 6m head versions of UPS and UPS2 pumps. Using the GO Replace app, suitability for replacing a wide range of internal boiler pumps can also be confirmed.
