Armstrong Fluid Technology 810120-003 Coupler
The Armstrong Fluid Technology 810120-003 Coupler is a precision-engineered OEM replacement part designed for high-performance hydronic systems. Specifically manufactured for Armstrong H-51 and H-52 circulator pumps, this four-spring type coupler facilitates efficient power transfer between the motor and the bearing assembly. Featuring a 1/2 inch x 1/2 inch shaft size and a robust cast iron construction, it is built to withstand the rigorous demands of HVAC pump repair and residential heating applications. This Armstrong 810120-003 spring coupler is an exact equivalent to the Bell & Gossett 118473, ensuring seamless integration and restoring optimal circulator pump performance. With its counter-clockwise rotation and reliable spring-loaded design, it effectively dampens noise and vibration, extending the operational life of your pumping equipment while maintaining peak system efficiency.
Key Benefits- Precise Compatibility: Engineered specifically for Armstrong H-Series (H-51, H-52) and identical B&G models.
- Heavy-Duty Durability: Constructed from high-quality cast iron for long-term reliability in thermal environments.
- Vibration Reduction: The 4-spring design absorbs mechanical shocks, leading to quieter operation and less wear on bearings.
- Standardized Fit: Features dual 1/2" yokes for universal alignment with 1/2 HP and 3/4 HP motor shafts.
Is the Armstrong 810120-003 interchangeable with Bell & Gossett parts?
Yes, this coupler is the direct functional equivalent to the Bell & Gossett 118473 model and can be used as a drop-in replacement.
What causes these couplers to fail?
Most failures are caused by motor misalignment or worn pump bearings, which put excessive stress on the spring assembly. Regular inspection of the alignment is recommended during installation.
Does this kit include more than one size of yoke?
This specific model features a 1/2" x 1/2" yoke configuration. Always verify your motor and pump shaft diameters before ordering.
Disclaimer: While we strive for 100% accuracy, product data and specifications are subject to change. Please contact our team to confirm compatibility or technical details before purchasing.
