Product Specifications

56Y Square-Flange Motor

The 56Y frame uses the square-flange mounting configuration commonly found on many in-ground pool pumps.

The motor mounts directly to the pump's seal plate, while the threaded shaft connects to the pump impeller.

When replacing an existing motor, customers should verify more than just the listed horsepower. Check the existing motor nameplate for:

• Horsepower
• Service factor
• Total horsepower
• Voltage
• Frame designation
• Flange configuration
• Shaft style
• Pump manufacturer and model

Match Total Horsepower

Replacement motors should be selected according to Total Horsepower (THP) rather than horsepower alone.

The B2849 is rated:

1.5 HP × 1.50 Service Factor = 2.25 THP

A replacement motor should meet the performance requirements of the pump's original motor and impeller configuration.

Durable Pool & Spa Construction

Century designed the B2849 specifically for pool and spa pump environments.

The stainless-steel threaded shaft offers improved resistance to corrosion in pool equipment areas, while sealed ball bearings provide smooth operation and long-term durability.

Its Permanent Split Capacitor motor design provides dependable single-speed performance, while built-in thermal protection helps protect the motor against damaging operating temperatures.

Important: Replace the Pump Shaft Seal

Always install a new mechanical shaft seal when replacing a pool pump motor.

The mechanical seal prevents pool water from traveling along the motor shaft and entering the motor.

Reusing an old shaft seal can result in:

• Water leakage
• Motor bearing failure
• Shaft corrosion
• Electrical damage
• Premature motor failure

The correct shaft seal is determined by the pool pump model, not by motor model B2849.

For best results, identify the exact pump manufacturer and model and install the appropriate shaft seal or pump go-kit during the motor replacement.

Motor Only

The Century B2849 is a replacement motor only.

Unless specifically stated otherwise, the following components are not included:

• Pump housing
• Seal plate
• Diffuser
• Impeller
• Mechanical shaft seal
• Pump gaskets
• O-rings
• Pump unions
• Electrical wiring

Always confirm pump compatibility before ordering.

Energy-Efficiency / Replacement Motor Notice

Federal efficiency requirements affecting dedicated-purpose pool pump replacement motors took effect beginning September 29, 2025. Depending on the application, replacement pool pump motors within the regulated horsepower range may be required to use variable-speed technology.

Customers and installers should confirm whether the B2849 is permitted for their specific replacement application and jurisdiction before installation.
