Description
Meet the AOS Century Premium H741 C-Face Threaded Hub pool pump motor—an upgrade in reliability for serious pool systems. Built for continuous duty in demanding environments, this 3-phase, 60 Hz motor combines rugged construction with precise mounting and effortless serviceability to keep your filtration, heating, and water features running smoothly.
Why this motor stands out
- C-Face with threaded hub: Simplifies mounting directly to compatible pumps and accessories, delivering secure alignment and easy installation.
- Robust construction: Cast iron frame and NEMA C-bracket provide enduring support in outdoor pool environments, while a 303 stainless steel shaft resists chlorinated-water wear.
- Ball bearings for longevity: Smoother operation and extended life under typical pool-load conditions, reducing maintenance intervals.
- Capacitorless 3-phase design: Fewer components mean greater reliability and easier electrical wiring for commercial or residential pool systems.
- Dual-voltage versatility: Rated for 208-230V or 460V configurations, with 50/60 Hz compatibility to match a wide range of global installations.
- User-friendly mounting and compatibility: 56J frame size and standard C-Face footprint align with many Century, AO Smith, and Regal Beloit pool pump assemblies.
- Corrosion-aware materials: 303 stainless steel shaft and protective casting designed to withstand chlorinated pool environments and outdoor exposure (ambient up to 40°C).
What it does for your pool system
This motor powers pool pumps with steady, dependable headpressure to keep filters clean, water circulating efficiently, and debris from pooling in your system. The 3-phase configuration delivers robust performance for larger pools or higher-flow setups, while the threaded-hub, C-face design makes retrofits and replacements straightforward—minimizing downtime and labor.
Ideal use cases
- Replacing failing or underperforming pool pump motors in residential or light commercial installations.
- New installations where a durable, long-life 3-phase motor is preferred for high-flow filtration with a standard 56J frame.
- Systems that require a capacitorless 3-phase solution for simpler electricals and lower maintenance.

Practical tips for installation and care
To get the most from your H741 motor, pair it with a pump that matches its C-Face and 56J frame. Confirm your voltage supply is set for 208-230V or 460V and choose the correct wiring configuration for 50 Hz or 60 Hz operation. Mounting on a stable, level surface and ensuring adequate airflow around the motor will extend bearing life. Regularly check for any signs of vibration or unusual noise, and keep connection points tight to prevent arcing in outdoor pools with splash zones.
Whether you’re replacing an aging motor in a high-demand pool system or outfitting a new commercial setup, the C-Face Threaded Hub 3-Phase Pool Pump Motor from the H741 family delivers durable performance, straightforward installation, and long-term reliability you can trust for steady pool circulation year after year.
