Century B2984 2 HP Two-Speed Pool/Spa Pump Motor
Part Number: B2984
Description
A 2 HP dual-speed (3450/1725 RPM) full-rated pool pump motor with 230 V single-phase wiring and a 56Y square-flange (C-face) frame—designed to deliver reliable performance for circulation and filtration systems in residential pool and spa applications.
Compatibility & Fitment
- Fits pumps that require a 2 HP, two-speed motor with a 56Y frame and square-flange mounting.
- Ideal when the existing motor shows high current draw, worn bearings, excessive heat or vibration, or when upgrading to maintain or improve pump performance.
- Direct replacement for models originally specifying Motor B2984 with matching mounting, shaft, and electrical configuration.

- Voltage: 230 V single-phase (60 Hz)
- Amps: ~11.0 A (high speed) / ~1.8 A (low speed)
- Frame: 56Y square-flange (C-face)
- Shaft: Threaded stainless-steel shaft
- Service Factor: 1.30
- Enclosure: Open Drip-Proof (ODP) designed for continuous pool-service operation
Installation Notes
Ensure power is disconnected and the circuit is locked out before removal of the old motor. Remove the pump housing and original motor, verify mount dimensions, shaft configuration and wiring setup. Secure the new B2984 motor to the pump housing, align and connect the shaft, rewire per voltage label, and restore power. Run the pump to verify normal current draw, smooth operation and correct flow.
Maintenance Tip
During each service interval inspect the motor bearings, check for vibration or unusual noise, ensure the motor mount remains tight and the pump is primed and operating efficiently. Replace the motor if current draw rises, flow diminishes or bearing noise increases to protect downstream equipment and maintain consistent performance.
