Century Pool Pump Motor 2HP 1-Speed 1 Phase 60Hz 230V 56Y Frame | B2855
The Century B2855 is a heavy-duty, high-performance 2HP motor designed specifically for pool and spa applications. Engineered for reliability and quiet operation, the B2855 is the go-to choice for homeowners looking to restore their pump’s power without replacing the entire unit. This 56Y Frame motor features a Square Flange design, making it a direct replacement for many popular high-head pumps, including the Pentair WhisperFlo®, Challenger®, and SuperFlo® series.
Features
Universal 56Y Square Flange: Features the standard square mounting face with four non-threaded bolt holes, making it the essential "drop-in" replacement for high-performance Pentair, Sta-Rite, and Jandy pump housings.
Full-Rated Power Delivery: Rated at 2.0 HP with a high 1.30 Service Factor, this motor delivers a massive 2.60 THP. This extra power headroom ensures the motor runs cooler and more efficiently under the heavy loads of large pools and complex plumbing.
Corrosion-Resistant Threaded Shaft: The 5/8" diameter stainless steel threaded shaft is built to resist rust and chemical damage, providing a rock-solid connection to the pump impeller and ensuring it remains removable for future service.
Large 56Y Frame Construction: The 56Y frame provides a larger motor diameter than 48-frame models, allowing for better internal cooling and larger windings that can handle higher electrical loads without overheating.
Triple-Insulated Windings: Built with high-grade insulation to withstand high ambient temperatures and humidity, ensuring a long and reliable service life even in the harshest backyard climates.
Sealed Ball Bearings: Equipped with permanently lubricated, high-quality ball bearings that ensure quiet operation and reduce the need for ongoing mechanical maintenance.
Automatic Thermal Protection: Includes an internal thermal overload switch that automatically resets, protecting the motor from permanent damage due to overheating, jammed impellers, or voltage surges.

Notes
Common Pump Compatibility
The B2855 is a direct replacement for square-flange motors on these popular high-flow pumps:

Important Installation Tip
Mandatory Shaft Seal Replacement: High-horsepower motors like the B2855 generate significant torque and heat. Never reuse an old mechanical shaft seal. A compromised seal is the primary cause of premature motor failure. Ensure you purchase a new seal kit (e.g., PS-1000 for WhisperFlo) to protect your investment and maintain your warranty.
