The Grundfos UP 15-42F Super Brute Recirculation Pump (Model 59896155) is a high-efficiency, heavy-duty 3-speed circulator pump engineered for a massive range of hydronic heating, radiant floor, solar heating, and chilled water loop configurations. Featuring a reliable wet-rotor design with an integrated removable check valve, the Super Brute provides customizable performance curves, allowing plumbing and HVAC technicians to fine-tune system flow rates to match exact zone requirements with a simple flip of a switch.
Key Performance Features:
- 3-Speed Manual Adjustability: Allows quick, on-site system balancing. Replaces multiple single-speed pumps by adjusting performance seamlessly between Low, Medium, and High settings to optimize energy consumption.
- Whisper-Quiet Wet-Rotor Technology: The pumped fluid lubricates the internal bearings, eliminating the need for mechanical seals and manual oiling while delivering completely silent operation in residential and commercial spaces.
- Integrated Non-Return Check Valve: Features a removable, spring-loaded check valve (Check-V) that prevents reverse gravity circulation during off-cycles, ensuring consistent, targeted zone control.
Application Profile: Built with a rugged cast iron housing, this model is designed explicitly for closed-loop applications, including baseboard radiation, multi-zone radiant tubing layout matrices, wood-fired boiler loops, and water-source heat pump configurations. (Note: For open domestic potable water systems, utilize the stainless steel or bronze versions instead).
