Grundfos 59896180 Pump
The Grundfos 59896180 UPS15-42F is a high-performance 3-speed circulator pump engineered for precision flow control in closed-loop hydronic heating and cooling systems. Built with a cast iron housing and featuring a 1/25 HP wet-rotor design, this unit delivers a maximum flow of 17.5 GPM and a maximum head of 15.5 feet. The 230V circulator pump utilizes a canned rotor design where the pump and motor form an integral unit without a shaft seal, ensuring quiet, maintenance-free operation for demanding HVAC applications. This Grundfos UPS series model is an ideal solution for hot water recirculation and radiant heating loops, offering internal thermal protection and a broad liquid temperature range of 36°F to 230°F. The 59896180 is designed for standard 2-bolt flange connections, making it a reliable drop-in replacement for worn-out booster pumps in residential or light commercial mechanical rooms.
Key Benefits- Versatile Performance: Three selectable speeds allow for precise matching of pump output to system requirements, optimizing energy consumption and reducing hydraulic noise.
- Durable Construction: Heavy-duty cast iron volute ensures long-term structural integrity in closed-loop hydronic systems.
- Service-Free Design: The liquid-cooled wet rotor eliminates the need for mechanical seals and manual lubrication, significantly reducing maintenance downtime.
- Whisper-Quiet Operation: Advanced wet-rotor technology ensures near-silent performance, making it suitable for sound-sensitive residential installations.
- Thermal Protection: Integrated high-temperature protection prevents motor burnout under extreme operating conditions.
What is the primary application for this 230V circulator?
The Grundfos UPS15-42F is specifically designed for 230V closed-loop systems, such as hydronic baseboard heating, radiant floor heating, and indirect water heaters. It is not intended for open-loop potable water systems due to its cast iron housing.
Does this pump require a capacitor for startup?
Yes, this model features a built-in 2 µF/400 V run capacitor and internal thermal protection, meaning no external motor protection is required for standard operation.
Can I replace a 115V pump with this model?
No, the 59896180 is rated strictly for 1 x 230V power supplies. If your system is currently wired for 115V, you should look for the UPS15-58FC or a similar 115V equivalent to avoid electrical damage.
