Description

The Pentair 357204S motor package is designed as a drop-in replacement for failing motors in the C-Series commercial line. This 7.5 HP, 230V, single-phase motor provides the power and durability needed for high-flow, high-use pool environments. It restores compression and head capacity lost due to motor wear, while maintaining reliable electrical compliance and mechanical robustness. With parts matched to Pentair’s Purex lineup, this motor gives you OEM quality and performance.

Pro Tip

Make sure the power supply is rated for the motor’s current draw — using undersized wire or breakers causes overheating and shortened life. When you open the pump, inspect the mechanical seals, shaft sleeves, and impellers. Replacing worn parts while the motor is exposed prevents future leaks or failures. For optimal performance, balance the hydraulic components (impeller, diffuser) after motor installation.

Installation Tips

Ensure power is off and locked out before removing the old motor. Confirm the pump model is C-Series (CH-75 / CM-75) and that the voltage is 230V single phase. Use appropriately sized wiring and a breaker. Align motor shaft squarely with the pump coupling; torque bolts per manufacturer spec. Test for leaks and vibration before full use.
