Grundfos 52722512 Pump
The Grundfos 52722512 UPS26-99FC is a high-performance, 3-speed cast iron circulator pump designed for high-head applications in residential and commercial closed-loop hydronic systems. This 1/6 HP wet rotor circulator features an Integral Check Valve (IFC), which eliminates the need for external check valves, reducing installation time and material costs. With a 115V single-phase motor and a versatile 3-speed switch, this Grundfos Super Brute allows technicians to fine-tune the system's flow rate up to 33 GPM or head pressure up to 29 feet. The UPS26-99FC 115V is ideal for radiant floor heating, baseboard radiators, and fan coil units where whisper-quiet operation and maintenance-free reliability are non-negotiable. Its 2-bolt flange connection and standard 6.5-inch port-to-port length make it a direct drop-in replacement for numerous single-speed models. Built with a composite impeller and ceramic shaft, it handles liquid temperatures ranging from 36°F to 230°F at a maximum operating pressure of 145 PSI.
Key Benefits- 3-Speed Versatility: The adjustable motor allows for precise matching of the pump curve to system requirements, replacing over a dozen different single-speed pump models.
- Integral Check Valve (IFC): Prevents backflow and gravity circulation without the pressure drop or installation complexity of external valves.
- Internal Thermal Protection: The auto-resetting thermal switch protects the motor against overheating, ensuring long-term performance in demanding hydronic loops.
- Whisper-Quiet Operation: Designed with a wet rotor and water-cooled motor for silent performance in sound-sensitive residential environments.
- Standard Flange Compatibility: Compatible with GF 15/26 flange sets for easy integration into existing iron pipe or copper manifold systems.
What is the difference between the 52722512 UPS26-99FC and the UP26-99F?
The UPS26-99FC (52722512) is a 3-speed model with a built-in check valve, whereas the UP26-99F is a single-speed model without an internal check valve. The 3-speed switch makes the UPS26-99FC a more flexible replacement part for balancing different zones.
Can this pump be used in an open-loop domestic hot water system?
No, this model features a cast iron housing intended for closed-loop heating systems only. For domestic open-loop potable water applications, a stainless steel or bronze housing model must be used to prevent corrosion.
Does this pump require a capacitor for startup?
Yes, it utilizes a 20 µF/180 V run capacitor, which is pre-installed in the terminal box for ready-to-wire 115V installation.
