Armstrong Fluid Technology 816304-317K Plastic Impeller
The Armstrong Fluid Technology 816304-317K Plastic Impeller is a precision-engineered circulator pump replacement part designed to restore peak hydraulic efficiency to your HVAC system. This 5 1/4" Noryl impeller is manufactured from high-quality, non-ferrous composite materials, offering superior corrosion resistance and durability in demanding hydronic applications. As the official 816304-317K maintenance kit, it serves as the direct OEM pump impeller replacement for the legacy 816304-317 model, now featuring an integrated washer for improved stability and rotational balance. Specifically designed for Armstrong H-54 pumps, Armstrong S-57 pumps, and Series 1050 (2B) bearing assemblies, this component ensures optimal flow rates while reducing energy consumption. Whether you are performing a routine circulator pump repair or addressing a loss in system pressure, this genuine Armstrong component provides the exact tolerances required for industrial-grade fluid handling. Use this HVAC replacement impeller to ensure your circulator operates with minimal noise and maximum reliability.
Key Benefits- Enhanced Durability: Constructed from glass-filled Noryl for excellent heat resistance and chemical stability.
- Optimized Performance: The 5.25-inch diameter and specialized blade geometry maximize fluid throughput.
- Direct Upgrade: Replaces part number 816304-317 with an added washer for a more secure fit.
- Wide Compatibility: Fits Armstrong H-54, S-57, and Series 1050 2B pumps.
- Non-Ferrous Build: Ideal for systems where rust prevention is a critical operational priority.
Is the 816304-317K compatible with Bell & Gossett pumps?
Yes, this 5.25" impeller is often cross-referenced as a suitable replacement for certain Bell & Gossett Series 60-4 circulators, though you should verify dimensions before installation.
What is included in the 816304-317K kit?
This kit typically includes the Noryl impeller, an impeller nut, a lock washer, and a casing gasket/O-ring to facilitate a complete repair.
Why should I choose plastic over bronze?
Noryl plastic impellers offer a lightweight, cost-effective, and corrosion-proof alternative to traditional bronze, specifically designed for modern hydronic heating and cooling systems.
