Armstrong Fluid Technology 816304-051 Impeller
The Armstrong Fluid Technology 816304-051 Impeller is a precision-engineered 4.75" bronze impeller designed for high-efficiency fluid circulation in commercial and industrial HVAC systems. Specifically crafted for the Armstrong S-55 Series circulator pump and 1050-2B pump models, this non-ferrous component ensures long-term resistance to corrosion and scaling. Its robust construction facilitates optimal flow rates and maximum pump efficiency, making it a critical pump replacement part for maintaining hydronic system performance. By utilizing high-grade bronze, this centrifugal pump impeller provides superior heat dissipation and structural integrity compared to plastic alternatives. This Armstrong 816304-051 model is essential for contractors looking to restore factory-spec pressure and velocity in closed-loop heating or cooling applications. Whether you are performing routine maintenance or a full system overhaul, this authentic 4.75-inch impeller ensures your Armstrong S-5 model continues to operate with minimal vibration and localized cavitation.
Key Benefits:
- Corrosion Resistance: High-quality bronze construction prevents degradation in water and glycol-based systems.
- Exact Compatibility: Precision-fit for Armstrong S-55 and 1050 Series pumps to ensure seamless installation.
- Enhanced Efficiency: Restores the intended performance curve and provides optimal flow rates.
- Industrial Durability: Robust design withstands the thermal stresses of commercial HVAC pumping.
Common Questions:
Will this impeller fit the Armstrong S-57 model?
No, the 816304-051 is specifically a 4.75" impeller for the S-55 and 1050-2B. Larger pumps like the S-57 typically require a 5.25" variant.
Does this include the mechanical seal and gasket?
This SKU represents the individual bronze impeller. For a full repair, it is often recommended to purchase the 816304-051K kit, which includes the necessary seals.
Can I use this in a potable water system?
Yes, the lead-free bronze material is suitable for a variety of fluid applications, including hydronic heating and general water circulation.
