Grundfos 59896118 Pump
The Grundfos 59896118 UP15-18B5 Circulator Pump is a high-performance hot water recirculation pump engineered for precision in residential and light commercial hydronic systems. Featuring a rugged bronze pump housing (CuZn16Si4-C), this 230V single-speed unit is purpose-built to handle potable water systems where corrosion resistance is non-negotiable. The 1/25 HP motor operates at a quiet 90W power input, delivering a maximum head of 13.78 ft and a rated flow of 4.93 GPM. Designed with a 1/2" internal sweat connection and a compact 5-inch port-to-port length, this Grundfos UP15-18B5 allows for seamless integration into tight piping arrays. Its wet-rotor design ensures maintenance-free operation by utilizing the pumped liquid to lubricate the bearings, significantly reducing mechanical wear. Whether you are servicing a domestic hot water system or an open-loop heating circuit, this energy-efficient circulator provides the hydraulic reliability expected by trade professionals.
Key Benefits for the Contractor:
- Corrosion-Resistant Bronze Construction: Built with ASTM B584 C87500 bronze to ensure longevity in oxygen-rich potable water environments.
- Reliable Open-Loop Performance: Specifically designed for systems where cast iron components would fail due to oxidation.
- Industry-Standard Dimensions: The 5-inch port-to-port length and 1/2" sweat connection facilitate fast drop-in replacement for existing circulator footprints.
- High-Temperature Resilience: Capable of handling liquid temperatures up to 230°F, making it suitable for demanding hydronic applications.
- Certified Safety Standards: UL and CSA approved to meet strict plumbing and electrical codes for North American installations.
Common Questions:
Can the Grundfos 59896118 be used in radiant heating?
Yes, the Grundfos UP15-18B5 is an excellent choice for radiant floor heating and hydronic systems, particularly where high-head performance is required in a small-wattage motor.
Is this pump compatible with 115V power?
No, this specific model is a 230V unit. Always verify the voltage at the terminal box before installation to prevent motor damage.
Does this model include a built-in check valve?
Technical specifications for the 59896118 indicate it does not include an internal check valve; however, an external Grundfos check valve can be installed if required by the system design to prevent backflow.
