Why choose a two-speed motor for your pool? At high speed, you get robust turnover for quick cleaning, backwashing, or when you need stronger suction. At the low speed, you benefit from quieter operation and significant energy savings during longer filtration cycles. This balance helps reduce running costs over the swimming season while maintaining clear, well-circulated water.

Designed for straightforward replacement, this motor’s square flange mounting and 56Y frame compatibility mean fewer compatibility headaches and less downtime during installation. The top-mounted capacitor simplifies serviceability, so you can swap components without extensive disassembly.

Ideal for pool owners, service professionals, and installers who need a trusted, widely compatible 2-speed option that supports standard 115V pool circuits. It’s a practical upgrade for existing systems using the SQL1072R family and a reliable foundation for consistent circulation across seasons.

Smart integration tips:

• Verify your pump housing accepts a 56Y square-flange motor and that the shaft alignment matches your current coupling (threaded shaft ensures a secure fit).
• Use the high-speed setting for brief, intensive tasks and switch to low-speed for longer filtration periods to optimize energy use.
• Since the capacitor is on top, replace with the correct top-capacitor variant during service to preserve performance and reliability.
• Check wiring to ensure your control system or timer is configured for 1-phase, 115V operation and the two-speed control you plan to use.

Upgrade your pool’s pump performance with the proven reliability of A.O. Smith Century SQL1072R115V. A thoughtful blend of durability, adaptability, and energy-conscious operation, it’s designed to keep water clear, inviting, and properly circulated year after year.
