The product listing emphasizes a broad compatibility range, with a 1.1 service factor and modern windings to ensure reliable operation. installation requires standard wiring in a terminal box and attention to frame-fit alignment.
Key considerations: confirm your pump’s flange type and shaft length; verify the capacitor and wiring kit compatibility; ensure the motor’s service factor meets your pool’s load conditions; verify the voltage selection procedure in the manual for correct 115V/230V operation. For long-term performance, pairing a new motor with proper seal kits and gland packing is recommended to prevent leaks and minimize maintenance.
B2855 2 Horsepower Pool Pump Motor
This WINNEWBEAUTY B2855 motor is a 2HP square-flange unit designed as a replacement for Century B2855 and related models, as well as A.O. Smith equivalents. It operates at 60 Hz, with a 3450 RPM top speed and a 56Y frame. The listing notes broad compatibility with a range of above-ground and inground pool pumps, including Jandy/Waterpik and several Century/A.O. Smith variants. It supports dual-voltage setup via wiring in the terminal box, highlighting ease of 230V to 115V reconfiguration. The motor aims for efficient, single-phase operation and is pitched as a direct swap for many common pump assemblies.
Purchase considerations: verify your pump’s model numbers to align with the OE numbers listed (for example B2855, B855, and associated part variants). Ensure the mounting flange matches your current housing and take stock of the included or required seal components to prevent leaks after installation. Evaluating amperage requirements helps avoid overheating under high-flow conditions.
B2855 2HP Pool Pump Motor Replaces B855 and More

Buying Guide: Key Purchase Considerations
- Motor Frame and Flange: Match the 56J or 56Y frame and check if a square flange or round flange is required for your pump model. Incorrect mounting can cause leaks or mechanical interference.
- Voltage and Frequency: Most 2HP pool motors operate at 230V single phase or 115V/230V dual voltage. Ensure your electrical supply and the wiring configuration support the chosen motor without overloading circuits.
- Compatibility: Use OE numbers and model families listed by manufacturers to verify compatibility with your Hayward, Pentair, Sta-Rite, or Jacuzzi pumps. When in doubt, compare the pump’s model tag with the motor’s listed equivalents.
- Current Draw and Service Factor: A 1.0–1.15 service factor is common. If you have a high-load pool or variable-speed needs, consider a higher service factor for reliability under peak flow.
- Seal Kit and Bearings: Ensure you have or can replace seals and bearings to prevent leaks and extend motor life. A good seal kit minimizes downtime and maintenance.
- Installation and Wiring: Follow the manual for terminal box wiring, ground connections, and capacitor requirements. If you’re not confident, consult a licensed electrician to meet electrical codes.
- Quality and Warranty: Consider brands with documented warranties and readily available replacement parts. A motor with reliable bearings and corrosion-resistant housing fares better in outdoor pool environments.
- Maintenance Planning: Plan periodic inspection of impellers, seals, and electrical connections. Clean ventilation surfaces and ensure no debris blocks airflow to maintain cooling efficiency.
Across these options, the choice depends on your existing pump compatibility, preferred brand ecosystem, and installation constraints. All five models offer 2HP power suitable for typical residential pools, with variations in frame, voltage, and OE-number compatibility. By aligning motor specs with your pump housing and electrical setup, you can achieve reliable circulation, efficient filtration, and long-term performance without frequent motor replacements.
