AO Smith UST1152 Pool Pump Motor

This single-speed motor delivers 1.5 HP at 3450 RPM for residential pool circulation. It operates on dual voltage at 115 or 230 volts with a 1.00 service factor. The 56J frame and threaded shaft suit standard C-face round flange installations.

Suits owners replacing a failed 56J-frame motor

Buyers needing variable-speed control for energy savings should look elsewhere. This unit runs at fixed 3450 RPM on 60 Hz supply only. Installations requiring a different frame size or keyed shaft will not match.

Threaded shaft simplifies impeller attachment

The 56J frame ensures direct bolt-on fit for compatible pump housings. Dual-voltage wiring allows connection to 115 V or 230 V circuits without internal changes. No additional accessories or software are included in the package.

Questions about this item

What voltage supply and amperage circuit must I already have for the 115/230 V, 18.6/9.3 A motor?

The motor runs on either 115 V drawing up to 18.6 A or 230 V drawing up to 9.3 A, so your electrical supply and breaker must match the voltage you choose.

Will the 56J frame and threaded shaft fit the C-face round flange on my existing pump housing?

Yes, the 56J frame with threaded shaft is designed for a C-face round flange mount, matching common residential pool pump housings that use this pattern.

How can I confirm the motor is running at the correct 3450 RPM after installation?

With a 60 Hz supply the motor’s synchronous speed is 3450 RPM; you can verify it with a handheld tachometer or by checking that the pump delivers its rated flow.
