Grundfos 52722557 Pump
For high-demand hydronic applications, the Grundfos 52722557 (Model UPS50-44F) stands as a heavy-duty, 3-speed cast iron circulator pump designed for seamless integration into closed-loop heating and cooling systems. Engineered with a 1/6 HP motor and operating on a standard 115V single-phase power supply, this wet-rotor unit delivers a maximum flow rate of 65 GPM and a maximum head of 14.4 feet. The canned rotor design eliminates the need for mechanical shaft seals, utilizing the pumped liquid for bearing lubrication to ensure whisper-quiet, maintenance-free operation in sound-sensitive environments. With its 4-bolt flange connection and versatile performance curve, the UPS50-44F 115V is a reliable choice for radiant heating, fan coil units, and solar thermal loops. The integrated motor protection and corrosion-resistant composite impeller provide long-term durability against technical wear in high-pressure installations up to 145 psi.
- 3-Speed Versatility: Adjustable performance settings allow for precise matching of flow requirements to system load, optimizing energy efficiency across varying hydronic heating demands.
- Maintenance-Free Reliability: The canned rotor unit and liquid-lubricated bearings eliminate periodic maintenance and the risk of seal leaks.
- Rugged Construction: Built with an ASTM A48-25B cast iron housing and a PES 30% GF composite impeller to withstand temperatures up to 230°F.
- Standardized Fit: Features a universal 2-inch, 4-bolt flange connection for straightforward drop-in replacement of existing inline circulator pumps.
Common Questions
What systems are compatible with the UPS50-44F?
This pump is designed specifically for closed-loop hydronic heating, radiant floor systems, and air conditioning applications. Because of its cast iron housing, it should not be used in open-loop potable water systems where corrosion is a factor.
How do I adjust the flow rate on this Grundfos pump?
The motor housing includes a manual 3-speed selector switch. Technicians can toggle between settings to find the ideal balance between system head pressure and required GPM without necessitating external controllers.
Does this unit require external motor protection?
No, the Grundfos 52722557 features built-in thermal protection suitable for the internal motor temperatures, simplifying the electrical installation process for contractors.
