UPS3 is a high-efficiency circulator pump designed for domestic heating systems with either variable or constant flow rate.
Highly efficient, the Grundfos UPS3 15-50/65 130 circulator pump is suitable for use as a universal upgrade and replacement pump, circulating liquids in domestic heating systems. This pump has a user-friendly one button interface for simple, fast set-up, while LEDs indicate actual operating status as well as providing warnings and alarms. Self-venting through the system, UPS3 offers easy commissioning, while the compact design, featuring a pump head with integrated control box, fits into most installations, including boilers, for simple fitting. Maintenance-free, the pump and motor are one integral unit with no a shaft seal, and bearings are lubricated by the pumped liquid.
