Century Pool Pump Motor, Square Flange, 2HP 48Y | USQ1202
The Century USQ1202 is a premium replacement motor designed for inground pool pumps that require a Square Flange (48Y Frame). With a 2.10 Total Horsepower (THP) rating, this motor is built to power large filtration systems, multi-jet spas, and demanding water features with ease. As a "full-rated" motor, the USQ1202 is the industry-standard replacement for many of the most powerful pumps from Pentair and Sta-Rite, offering a perfect mechanical fit and the rugged electrical build needed to survive hot, humid outdoor environments.
Features
Universal 48Y Square Flange: Features the standard square mounting face with four non-threaded bolt holes. This frame size is the essential "drop-in" fit for high-head pump housings from Pentair, Sta-Rite, and Jandy.
High-Performance Output: Rated at 2.0 HP with a 1.05 Service Factor, delivering a 2.10 THP. This ensures the motor has the "muscle" to maintain high flow rates even as your filter collects debris or when pushing water through solar heating arrays.
Stainless Steel Threaded Shaft: The 5/8" diameter threaded shaft is constructed from high-grade stainless steel to prevent rust and corrosion, ensuring your impeller stays securely attached and remains removable for future service.
Dual-Voltage Engineering: Designed to operate on either 115V or 230V circuits. Its Permanent Split Capacitor (PSC) design provides a smooth, quiet start and energy-efficient operation.
Advanced Cooling & Protection: The Open Drip-Proof (ODP) housing is engineered for maximum airflow to protect internal windings from heat stress, while the automatic-reset thermal protector prevents burnout from surges or jams.
Triple-Insulated Windings: Built with Class B insulation to withstand high ambient temperatures, ensuring a longer lifespan for the motor’s internal electrical components.

Notes
Common Pump Compatibility
The USQ1202 is a direct replacement for square-flange motors on these popular high-flow pumps:
Pentair: WhisperFlo, Challenger, and SuperFlo (Square Flange versions)
Sta-Rite: Max-E-Pro, Max-E-Glas, Dyna-Glas, and Dyna-Max
Jandy: PlusHP, Stealth, and FloPro
Important Installation Tip:
Never Reuse Your Old Shaft Seal: High-horsepower motors generate significant torque and heat. Replacing your motor without a new Mechanical Shaft Seal (e.g., PS-1000 for WhisperFlo) is the leading cause of "infant mortality" in new motors. A small leak can travel down the shaft and destroy your front bearing within weeks. Always install a new seal kit to protect your investment.
