The Grundfos UPS 50-60 SF circulator pump is a high-efficiency solution designed with a corrosion-resistant stainless steel pump housing, making it ideal for domestic hot water recirculation and underfloor (radiant) heating systems. Engineered for durability and consistent performance, this Grundfos UPS pump delivers reliable water circulation in both residential and light commercial hydronic systems. For enhanced energy efficiency and control, the UPS 50-60 SF can be connected to an external on/off timer switch, allowing operation during peak hot water demand periods only-reducing energy consumption and operating costs. Additionally, this model features a maintenance-free canned rotor design, integrating the pump and motor into one compact, sealed unit. With no mechanical shaft seal and only two gaskets, the pump minimizes leakage risk while ensuring long-term reliability. The system is self-lubricated by the pumped liquid, promoting smooth, quiet operation and extended service life.
