Details

Century and Nidec US Motors pump motors are widely trusted for replacement and upgrade work where dependable motor performance matters, and this 2.0 HP two-speed model uses the B2976 reference with a 230 volt supply, 56J frame, C-face threaded configuration, and 10.0 and 2.1 amp operating profile. As part of a strong replacement-motor family, it is especially appealing for buyers who need a recognizable motor platform with the right frame and speed configuration.

This motor has practical value because the two-speed setup offers more operating flexibility than a single-speed alternative while keeping the installation matched to a specific frame and mount style. The 56J and C-face threaded combination is particularly important for compatibility, helping customers avoid costly fit errors when replacing an existing motor.

This type of motor is especially useful when an original pool pump motor has failed but the wet end and surrounding pump assembly remain serviceable. Matching horsepower, frame, voltage, and speed configuration helps preserve performance expectations and support a cleaner replacement process.

Installed in the proper application, this Century motor helps support dependable pool pump performance, stronger replacement confidence, and proven long-term serviceability.
