Lochinvar & A.O. Smith 100277784 Impeller
The Lochinvar & A.O. Smith 100277784 Impeller is a critical OEM replacement part engineered for high-recovery commercial water heaters and industrial boiler systems. As the professional-grade successor to the legacy 100133556 part number, this centrifugal pump impeller ensures precision fluid dynamics and optimal head pressure within the heat exchanger circuit. Built to withstand the rigorous cycling of hydronic heating equipment, the 100277784 features a reinforced composite or metallic construction (system dependent) that maintains flow rate integrity and prevents cavitation-induced vibration. For veteran technicians, this genuine Lochinvar component is essential for restoring system GPM to factory specifications, particularly in A.O. Smith Cyclone series or Lochinvar Knight models that utilize the 100133556 cross-reference. Integrating this direct replacement impeller eliminates compatibility issues during troubleshooting, ensuring that the circulator pump assembly operates at peak mechanical efficiency without premature bearing wear or motor strain.
Key Benefits- Direct OEM Compatibility: Engineered as the specific factory-authorized substitute for the discontinued 100133556 part number.
- Optimized Flow Dynamics: Precision-balanced design reduces turbulence and increases hydraulic efficiency in commercial heating systems.
- Enhanced System Reliability: Restores proper internal circulation to prevent hot spots and localized scaling within the heat exchanger.
- Simplified Installation: Dimensional accuracy ensures a secure fit on the motor shaft, reducing labor time during pump teardowns.
Is the 100277784 compatible with models originally using 100133556?
Yes, the 100277784 is the manufacturer-designated direct replacement for the 100133556, offering improved material resilience and performance standards.
What are the symptoms of a failing blower or pump impeller in these units?
Technicians should look for increased operational noise, reduced flow velocity, or system-wide short cycling, which often indicates physical erosion or debris blockage in the impeller vanes.
Does this part fit both Lochinvar and A.O. Smith equipment?
As a shared part across the parent manufacturing group, this impeller is optimized for specific A.O. Smith and Lochinvar commercial boiler and water heater cross-platforms.
