Grundfos 96409356 Flange Set
The Grundfos 96409356 Flange Set is a heavy-duty 1.25-inch bronze flange kit designed for seamless integration with Grundfos UPS and TP series circulator pumps. Engineered for high-temperature and open-loop hydronic systems, these NPT threaded flanges provide a secure, leak-proof connection in domestic hot water applications where corrosion resistance is critical. This genuine Grundfos pump accessory includes two bronze flanges, high-grade EPDM gaskets, and the necessary zinc-plated bolts and nuts for a complete installation. The 1-1/4" NPT sizing ensures compatibility with standard piping, facilitating quick circulator pump maintenance and component replacement without altering existing system geometry. By utilizing cast bronze construction, this set minimizes galvanic corrosion in potable water systems, ensuring long-term structural integrity and reliable flow performance for commercial and residential HVACR projects.
Key Benefits- Corrosion-Resistant Bronze: Optimized for oxygen-rich environments and potable water systems to prevent premature oxidation.
- Precise 1.25" NPT Threads: Ensures a clean, mechanical seal with standard schedule 40 or 80 piping.
- Full Installation Kit: Includes pump gaskets and hardware, reducing downtime during field service calls.
- UPS and TP Series Compatibility: Engineered specifically for Grundfos pump housings to ensure exact bolt-hole alignment and pressure rating.
Is this flange set compatible with cast iron pump housings?
While the bolt patterns may align, using bronze flanges with cast iron pumps is typically reserved for systems requiring corrosion resistance; always verify that the pump housing material matches your system's fluid requirements.
Does this kit include gaskets?
Yes, this Grundfos flange kit includes two high-performance gaskets designed to withstand the thermal stresses of hydronic heating and cooling cycles.
What is the maximum pressure rating for these flanges?
These flanges are engineered to meet the standard operating pressures of Grundfos UPS circulators, typically rated for 145 to 150 PSI depending on the specific pump model and fluid temperature.
