Armstrong Fluid Technology 105189-011 Flange
The Armstrong Fluid Technology 105189-011 is a high-performance 2 1/2" 4-bolt flange specifically engineered for industrial and commercial hydronic systems. Constructed from rugged cast iron, this companion flange is a critical component for ensuring a leak-proof seal in demanding HVAC applications and fluid handling environments. It is a genuine replacement part primarily designed for the Armstrong S-45 circulator pump and is compatible with various circulating pump models and series, including S-46 and H-41. This industrial pump flange provides exceptional resistance to corrosion, rust, and mechanical wear, maintaining system integrity even under high-pressure conditions. Whether you are performing routine boiler maintenance or emergency HVAC repair, the precision-machined bolt holes and 1-1/2" NPT connection facilitate a secure, vibration-resistant fit. Trust this hydronic heating system component to optimize flow efficiency and extend the service life of your circulating equipment.
Key Benefits- Durable Cast Iron Construction: Provides superior strength and longevity compared to standard fittings in commercial plumbing.
- Optimized Compatibility: Designed specifically for Armstrong S-45 pumps, ensuring a perfect OEM-standard fit.
- Corrosion Resistance: Material properties are selected to withstand harsh environments and chemical exposure common in HVAC systems.
- Secure 4-Bolt Design: Evenly distributes pressure across the gasket surface to prevent leaks and handle higher mechanical loads.
- Versatile Application: Suitable for a wide range of piping configurations in both water supply and heating circuits.
Is the Armstrong 105189-011 compatible with other pump brands?
Yes, this flange is often used as a direct replacement for certain Bell & Gossett flanges that share the same 2 1/2" 4-bolt specifications.
What is the maximum operating temperature for this cast iron flange?
While typically rated for standard hydronic heating temperatures up to 250°F, it is essential to verify your specific gasket material and system pressure to ensure safe operation.
Does this item include the mounting hardware?
This specific SKU generally refers to the single cast iron flange. For complete installations, a separate hardware kit containing bolts, nuts, and gaskets may be required.
