Grundfos 95906633 Pump

The Grundfos 95906633, also known as the UPS26-150SF, is a high-performance 3-speed stainless steel circulator pump designed specifically for demanding hydronic and domestic hot water applications. Operating at 208-230V with a robust 1/3 HP motor, this "Super Brute" series pump is engineered for open or closed-loop systems where corrosion resistance is non-negotiable. The stainless steel pump housing ensures longevity in potable water and radiant heating environments, while the wet rotor design provides whisper-quiet operation by utilizing the pumped liquid to lubricate the internal bearings. Contractors often choose the Grundfos UPS26-150SF 230V for its versatile performance curve, capable of reaching a maximum head of 45 feet and a flow rate up to 52 GPM. Its 3-speed manual switch allows for precise system balancing, reducing energy consumption and hydraulic noise. With a standard 2-bolt flange connection and a 6-1/2" port-to-port length, it serves as a reliable drop-in replacement for high-head circulation requirements in residential and light commercial mechanical rooms.

• Corrosion-Resistant Construction: Features a high-grade stainless steel pump housing and composite impeller, making it ideal for domestic hot water and open-loop systems.
• Multi-Speed Versatility: The 3-speed motor allows technicians to adjust the pump to the specific head pressure and flow requirements of the system.
• Maintenance-Free Reliability: The canned rotor design eliminates the need for mechanical seals, preventing leaks and reducing long-term service calls.
• High-Temperature Compatibility: Engineered to handle liquid temperatures ranging from 36°F to 230°F, suitable for both chilled water cooling and high-temp hydronic heating.
• Internal Motor Protection: Built-in thermal protection ensures the 1/3 HP motor operates safely under varying load conditions without the need for external starters.

Common Questions Regarding the UPS26-150SF 230V:

Is this pump suitable for potable water systems?
Yes, because the 95906633 features stainless steel construction, it is compliant and safe for domestic hot water recirculation where lead-free components are required.

Can I replace a 115V model with this 230V version?
No, you must match the existing electrical supply. This unit is specifically rated for 208-230V single-phase power. Check your voltage at the terminal box before installation.

Does this pump include the flanges?
This model typically requires a pair of 2-bolt flanges (GF 15/26) which are generally sold separately to match your specific pipe size (3/4" to 1-1/2").
