Grundfos 59896123 Pump
The Grundfos 59896123 is a high-performance 1/25 HP bronze circulator pump engineered for 115V applications, including domestic hot water recirculation, hydronic heating, and solar thermal systems. This UP15-18BUC5 model features a lead-free bronze housing, making it essential for potable water loops where corrosion resistance is non-negotiable. Designed with a wet rotor and ceramic shaft, it provides a max flow of 14.5 GPM and a max head of 14.4 feet, ensuring reliable circulation in residential and light commercial settings. The integral check valve (IFC) and 1/2" sweat connection simplify installation by reducing external component requirements. With a high-efficiency composite impeller and stainless steel rotor can, this Grundfos circulator pump is built for continuous, low-maintenance operation in systems with pressures up to 145 PSI and fluid temperatures ranging from 36°F to 230°F. As a veteran-choice recirculation pump, it excels in maintaining consistent loop temperatures and reducing water waste.
Key Benefits- Corrosion-Resistant Housing: The bronze body is purpose-built for open systems and potable water, preventing mineral buildup and scale.
- Integrated Check Valve: Includes a built-in IFC to prevent backflow and gravity siphoning without needing additional inline hardware.
- Quiet Operation: Utilizing a canned-rotor design and ceramic radial bearings, the pump operates silently for indoor installations.
- Simplified Maintenance: The removable cartridge allows for internal servicing without disconnecting the pump from the main piping.
- System Protection: Rated for a max fluid temperature of 230°F and a robust 145 PSI operating pressure.
Can the terminal box be rotated for vertical or horizontal piping?
Yes. You can rotate the stator relative to the pump housing to ensure the conduit entry is in the correct orientation. However, the motor shaft must always remain horizontal to ensure the liquid-lubricated bearings function correctly.
Does this model replace the UP15-18B5 or UP15-18SU?
The UP15-18BUC5 is a direct replacement for several Grundfos UP series bronze pumps with 1/2" sweat or union connections. If your current unit uses a timer or line cord, those accessories can often be transferred or purchased separately.
Is this pump suitable for radiant floor heating?
While bronze is excellent for radiant floor heating, it is primarily required for open-loop potable systems. For closed-loop hydronic systems, a cast iron variant of the UP15-18 may be used unless local codes require non-ferrous components.
