Maintain peak hydraulic efficiency in your heating and cooling systems with this durable 5-1/4" non-ferrous replacement impeller. Engineered by Armstrong, the 816304-317K is designed to restore flow rates and reduce mechanical drag in compatible circulator pumps, specifically ensuring seamless compatibility with models like the S-57 and H-54 series.
This impeller operates by converting mechanical energy from the pump motor into fluid kinetic energy, optimizing pressure head and volumetric output. The precision-cast non-ferrous construction resists corrosion and mineral buildup, which helps mitigate vibration and protects the motor seal from premature wear caused by cavitation or imbalances.
Key System Performance Baselines:
- Hydraulic Efficiency: Precision blade geometry ensures optimal fluid transfer and reduced energy consumption.
- Corrosion Resistance: Non-ferrous material composition prevents oxidation for prolonged service life in hydronic loops.
- Balanced Operation: Dynamically balanced design minimizes bearing strain and acoustic output during high-speed rotation.
⚠️ Application Profile: Primarily used in Armstrong S-57 and H-54 series circulator pumps for commercial and residential hydronic heating, industrial process cooling, and secondary hot water loops.
