The AO Smith Century UST1102 is a powerhouse 1 HP replacement motor designed for the most popular pool pumps on the market. Featuring a 56J Frame with a threaded shaft and round flange, this motor is a direct replacement for many Hayward, Pentair, and Jacuzzi pumps. With its dual-voltage capability and high service factor, it delivers reliable, quiet performance season after season.

🚩 PRO TIP: When replacing your motor, we strongly recommend replacing your pump's shaft seal and O-rings at the same time. Reusing an old seal can lead to water leaks that will quickly damage the bearings of your brand-new motor.

PRODUCT FEATURES:

  • VERSATILE 1 HP POWER: Engineered for consistent performance in residential and commercial pool filtration systems.
  • DUAL VOLTAGE FLEXIBILITY: Ships ready for 230V but can be easily toggled to 115V to match your existing pool timer or sub-panel setup.
  • THREADED SHAFT (56J FRAME): Features a stainless steel threaded shaft for a secure fit and easy installation of the pump impeller.
  • SUPERIOR COOLING: Designed with high-quality ventilation to prevent overheating and extend the life of the internal windings.
  • ENERGY EFFICIENT: Features a 1.10 Service Factor, ensuring the motor runs cooler and more efficiently than standard "up-rated" motors.
