Bell & Gossett P49369 Impeller Key

For service technicians maintaining high-capacity hydronic systems, the Bell & Gossett P49369 Impeller Key is a critical hardware component for ensuring precise torque transfer and impeller alignment. This industrial-grade impeller key is specifically designed to secure the impeller to the motor shaft, preventing rotational slippage that can lead to catastrophic pump failure or decreased hydraulic efficiency. Engineered to meet exacting OEM tolerances, the P49369 features a 3/16-inch square profile with a 1-inch length, making it the standard replacement for Bell & Gossett Series 1510, Series e-1510, and Series 80 centrifugal pumps manufactured after August 1989. Its heavy-duty construction provides the shear strength necessary to handle the mechanical stresses of heating and cooling applications, including domestic water and general service operations. Utilizing genuine B&G pump parts like this key ensures that your pump shaft hardware maintains the integrity of the rotating assembly, minimizing vibrations and extending the operational life of the mechanical seal and bearings in demanding HVACR environments.

• Ensures consistent impeller-to-shaft synchronization to maintain peak GPM and head pressure performance.
• Compatible with a wide range of B&G Series 1510, e-1510, 1531, and Series 80 pump configurations.
• Precision-machined 3/16 sq x 1 lg dimensions provide a snug fit within the shaft keyway, reducing mechanical play.
• Engineered for industrial longevity in both hydronic heating and potable water systems.
• Facilitates accurate field repairs and routine maintenance on Xylem Bell & Gossett centrifugal assemblies.

What is the exact size of the P49369 impeller key?
The P49369 is a 3/16" x 3/16" square key that is 1" in length, designed specifically for a 1-1/4" motor shaft on compatible B&G pump series.

Does this key fit Bell & Gossett pumps manufactured before 1989?
This specific part is typically utilized for pump models built post-August 1989. For older units, it is recommended to verify the shaft diameter and keyway dimensions before installation.

Which B&G pump series use this hardware?
The P49369 is a primary spare part for Series 1510, e-1510, Series 1531, and Series 80 pumps, as well as several booster pump models including the Series HV and Series 2.
