Grundfos 59896114 Pump
The Grundfos 59896114, also identified by model UP15-18B5, is a high-performance, single-speed bronze circulator pump engineered specifically for open-loop systems. Designed for domestic hot water recirculation and hydronic heating, this 1/25 HP unit features a lead-free bronze housing that resists the corrosive effects of oxygenated water. As a canned rotor pump, the motor and pump form an integral unit without a mechanical shaft seal, utilizing the pumped liquid for bearing lubrication to ensure whisper-quiet operation in sound-sensitive residential or commercial environments.
Operating at 115V with a 1/2-inch internal sweat connection, the UP15-18B5 delivers a maximum flow of 14.5 GPM and a maximum head of 13.78 feet. The technical construction includes a ceramic shaft, carbon radial bearings, and a PES composite impeller, making it a robust solution for potable water systems. With a fluid temperature range of 36°F to 230°F and a maximum pressure rating of 145 PSI, this maintenance-free circulator is a standard choice for contractors looking for energy-efficient pumping and long-term reliability in specialized HVACR applications.
Key Benefits- Corrosion Resistance: Lead-free bronze housing is ideal for continuous oxygen-rich domestic water circulation.
- Quiet Performance: Wet rotor design eliminates the need for a fan, providing nearly silent operation.
- Simplified Installation: Standard 1/2" sweat ports and a compact 5-inch port-to-port length allow for easy integration into tight piping runs.
- Low Maintenance: Self-lubricating bearings and a seal-less design reduce service calls and downtime.
- Thermal Protection: Built-in impedance protection ensures the motor remains safe under locked-rotor conditions without additional external starters.
Can the UP15-18B5 be installed with the motor shaft pointing down?
No. To prevent air binding and bearing failure, the pump must be installed with the motor shaft in a horizontal position. The terminal box can be rotated to the 12, 3, 6, or 9 o'clock positions as needed.
Is this pump compatible with a 24-hour timer?
Yes, this model is compatible with standard Grundfos 24-hour programmable timer kits, which help reduce energy consumption by running the pump only during peak demand periods.
How do I clear an airlock in the system?
If the pump is running but not moving water, ensure the system is properly vented. You can manually rotate the shaft by removing the large silver plug on the front of the motor and using a flathead screwdriver to ensure the impeller is free of debris or mineral buildup.
