Grundfos 59896786 Pump
The Grundfos 59896786, model UP15-55SUC, is a single-speed stainless steel circulator pump engineered for precision performance in domestic hot water recirculation and open-loop heating systems. Operating at 230V with a 1/13 HP motor, this canned rotor pump integrates the motor and pump into a single unit without a shaft seal, utilizing the pumped liquid for bearing lubrication to ensure whisper-quiet operation. The AISI 304 stainless steel housing provides critical corrosion resistance for potable water applications, while the built-in check valve prevents backflow. With a maximum flow rate of 21.6 GPM and a max head of 17 feet, this unit handles system pressures up to 145 PSI. Designed for reliability in radiant floor heating and solar thermal systems, the UP15-55SUC 230V features 1-1/4" NPSM union connections (unions sold separately) for straightforward installation in tight mechanical spaces. This maintenance-free circulator is a staple for contractors requiring a high-duty, energy-efficient solution for hot water recirculation.
- Corrosion-Resistant Reliability: Features a stainless steel pump housing and composite impeller (PES+30% GF) to withstand aggressive water conditions in open systems.
- Silent Maintenance-Free Operation: The canned rotor design eliminates mechanical seals and internal friction, relying on liquid-cooled ceramic bearings for extended service life.
- Integrated Backflow Prevention: Includes a removable, built-in check valve and isolating valves to simplify plumbing and protect the system hierarchy.
- Flexible System Compatibility: Compatible with solar heating, chilled water pumping down to 36°F, and standard residential hydronic loops.
Common Questions
Is the 230V model compatible with standard 115V residential outlets?
No, the Grundfos 59896786 is specifically wound for 230V single-phase operation. Attempting to run this on 115V will result in motor failure or failure to start. Ensure your power supply matches the 230V rating before installation.
Does this pump include the union connectors?
This model features 1-1/4" NPSM union housing but does not include the union nut and tailpiece sets. You must purchase 3/4" or 1/2" Grundfos union sets (such as 529912 or 529913) separately to complete the pipe connection.
Can this pump be used in a potable water system?
Yes, because it utilizes a stainless steel housing rather than cast iron, it is lead-free compliant and suitable for continuous circulation of potable domestic hot water.
