About the Grundfos UPSe ECM Recirculation Pump, 1/20 HP, 115V, 9H, Cast Iron, Flange - 15-58F (92603106)

Keep the flow steady with a pump that's always ready!


The UPSe 15-58F circulating pump with cast iron flange and check valve from Grundfos is designed to optimize the circulation of liquids within heating systems. Featuring an electronically commutated motor (ECM), this pump offers the best HI energy rating on the market. What’s more? Its operating panel provides quick access to three control modes—constant curve (zone pump), constant pressure (zone valve), and proportional pressure (thermostatic radiator valve (TRV))—each with three pump settings to suit your specific needs. These versatile control modes allow you to optimize the pump’s performance according to the demands of your system, enhancing both comfort and efficiency.


With a maximum flow rate of 13.6 GPM and a liquid temperature range from 36 degrees to 230 degrees Fahrenheit, this UPSe 15-58F circulating pump is designed to handle a wide variety of indoor applications. Dry-run protection is another standout feature of this pump. By detecting the absence of water and automatically stopping the pump, this feature prevents potential damage and costly repairs, ensuring longevity and efficiency. Not only that, but noise and performance issues are a thing of the past with this circulator pump’s automatic self-venting feature. Self-venting eliminates air pockets within the system, which can cause noise and reduce efficiency. Additionally, its intuitive troubleshooting system is equipped with warning and alarm lights that help you quickly identify and resolve issues, minimizing downtime.


Operating on a supply voltage of 115 volts with a power usage ranging from 3 to 38 watts, this pump provides a reliable solution for your heating system needs. Moreover, it offers flexible installations in tight spaces with its compact conduit box. In line with that, the toolless lever connector adds convenience by enabling quick and secure electrical connections, reducing installation time and complexity. Lastly, this pump also boasts an unblocking feature that minimizes the risk of blockages with its non-magnetic shafts and bearings. In the rare event of a blockage, the pump's intelligent system shifts between different torque levels to shake the rotor loose, ensuring continuous operation. To know more about what this pump has to offer, you can read through our Introducing Grundfos UPSe and New ALPHA Circulator Pumps blog.
