Grundfos 59896121 Pump
The Grundfos 59896121 is a high-performance bronze circulator pump designed specifically for open-loop systems, including domestic hot water recirculation and radiant heating applications. Built with a 1/25 HP maintenance-free motor, the UP15-18B7 handles a maximum flow of 14.7 GPM and a head range up to 13.9 feet, ensuring efficient fluid movement in residential and light commercial settings. The bronze housing provides superior corrosion resistance when pumping oxygenated potable water, preventing the oxidative failure common in cast iron alternatives. Operating at a standard 115V and 60 Hz, this single-speed internal sweat pump features 3/4" connections for direct soldering into copper plumbing lines. Its wet-rotor design and impedance protection ensure whisper-quiet operation and long-term thermal safety in sound-sensitive environments. Whether integrated into a solar heating loop or a chilled water system, this hydronic heating pump delivers reliable, constant-speed performance with a compact 6.42" port-to-port length for easy installation in tight mechanical spaces.
- Corrosion Resistance: The 100% bronze pump housing is essential for potable water and open-loop systems where oxygen is present.
- Quiet Operation: Encapsulated rotor and composite impeller design provide whisper-quiet performance suitable for indoor residential use.
- Compact Integration: Featuring a 3/4" internal sweat connection, this model allows for a professional, leak-resistant fit directly onto copper piping.
- Thermal Safety: Integrated motor protection prevents overheating, maintaining performance even during high-demand 230°F liquid temperatures.
Common Questions
Can the Grundfos UP15-18B7 be used for potable water?
Yes, the bronze housing is specifically engineered to meet lead-free requirements and resist corrosion in potable hot water recirculation systems.
What is the maximum fluid temperature this pump can handle?
This Grundfos circulator is rated for a liquid temperature range of 35.6°F to 230°F, making it suitable for high-temperature hydronic and solar applications.
How should this pump be oriented during installation?
For optimal longevity, the motor shaft must be positioned horizontally. It can be installed in both vertical and horizontal pipes, provided the electrical terminal box is not positioned below the pump.
