Century Centurion Pro HSQ125 1.25 HP Pool Spa Motor 115/230V 48Y Sq Flange

The Century Centurion Pro HSQ125 is a 1.25 THP single-speed pool and spa pump motor built for reliable, high-performance operation. Featuring a 48Y square-flange frame and dual-voltage 115/230V capability, this motor is a direct drop-in replacement for most residential pool and spa pump applications requiring a 48Y frame motor.

🚩 PRO TIP

Before ordering, verify your existing motor's frame (48Y), voltage (115V or 230V), and shaft diameter. The HSQ125 uses a threaded stainless-steel shaft — confirm your pump's impeller is compatible. For above-ground pools, the 115V wiring is most common; in-ground pools typically run 230V for better efficiency.

FREQUENTLY ASKED QUESTIONS (FAQ)

Is this a single-speed or variable-speed motor? The Century HSQ125 is a single-speed motor. It is a direct, cost-effective replacement for existing single-speed setups.

Does this motor come with the pump housing or impeller? No, this listing is for the replacement motor only. You will reuse your existing wet end (pump housing, impeller, diffuser). We highly recommend replacing your pump shaft seal when installing a new motor.

How do I know if my voltage is 115V or 230V? This motor is dual-voltage and can be wired for either. You must check your breaker or the wiring diagram on your old motor. The motor is factory-set to 230V, so you will need to switch the internal voltage dial if your setup requires 115V.
