Century Pool Pump Motor 1HP 1-Speed 1 Phase 60Hz 230/115V 56Y Frame | B2853V1
The Century B2853V1 is a premium, up-rated replacement motor designed for high-head pool pumps that utilize a Square Flange (56Y Frame). With a 1.25 Total Horsepower (THP) rating, this motor provides the reliable torque and flow required for standard filtration, automatic pool cleaners, and residential water features. A direct evolution of the trusted B853 and B2853 models, the B2853V1 is the industry-standard choice for powering elite pumps like the Pentair WhisperFlo and Sta-Rite Max-E-Pro, offering a perfect mechanical fit and long-term electrical stability.
Features
Universal 56Y Square Flange: Features the standard square mounting face with four non-threaded bolt holes, making it the essential replacement for high-performance Pentair, Sta-Rite, and Jandy pump housings.
Up-Rated Power Delivery: While rated at 1.0 HP, the 1.25 Service Factor provides a 1.25 THP output. This "extra" power ensures the motor runs cooler and handles the resistance of dirty filters or long plumbing runs more effectively.
Precision Threaded Shaft: The 5/8" stainless steel threaded shaft is built to resist corrosion and chemical damage, providing a rock-solid connection to your pump’s impeller.
Dual-Voltage Versatility: Easily switchable between 115V and 230V to match your existing pool pad wiring. The Permanent Split Capacitor (PSC) design ensures energy-efficient operation and a quiet startup.
Triple-Protected Windings: The Open Drip-Proof (ODP) enclosure is designed for maximum cooling airflow, while the internal windings are treated to resist moisture and high ambient temperatures.
Safety First: Equipped with automatic-reset thermal overload protection, which prevents motor burnout in the event of a jammed impeller or a voltage surge.

Notes
Common Pump Compatibility
The B2853V1 is a direct "drop-in" motor for square-flange versions of these popular pumps:
Pentair: WhisperFlo, Challenger, SuperFlo (Square Flange), and Pinnacle
Sta-Rite: Max-E-Pro, Max-E-Glas, Dyna-Glas, and Dyna-Max
Jandy: PlusHP, Stealth, and FloPro
Important Installation Tip:
Do Not Reuse Old Seals: Replacing a motor without replacing the Mechanical Shaft Seal is the most common cause of "new motor" failure. Even a tiny drip from an old seal will travel down the shaft and destroy the front bearing of your brand-new motor. For a Pentair WhisperFlo, you will need a PS-1000 seal; for most Sta-Rite pumps, a PS-200 or PS-3867.
