Grundfos UPS2 Universal Replacement Circulator Pump
The Grundfos UPS2 is a compact, high-efficiency, EuP 2015 compliant replacement for Grundfos UPS 4m, 5m, and 6m circulator pumps in tight-fit installations such as boilers. Combining legendary Grundfos reliability with maximum compatibility and fast, easy retrofit, through new electronics and hydraulics, just one model of UPS2 replaces 4m, 5m, or 6m versions of the old UPS pumps. The identical cable gland minimizes rewiring time, and where the existing base is in good condition, you can simply buy and replace the pump head—no need to disconnect pipework, minimizing access issues and leakage risks.
As an authorized Grundfos Water Pump Dealer in Dubai, we supply the complete UPS2 range with genuine warranty and technical support across the UAE.
