Benefits

The Pentair 354822S motor helps restore proper pump operation when the original motor becomes loud, overheats, fails to start, trips breakers, or loses performance. Replacing only the motor can be a cost-effective repair when the pump housing, seal plate, impeller, diffuser, basket, lid, and plumbing are still in good condition.

The TEFC design is especially useful for equipment pads exposed to moisture, dust, salt air, and harsh outdoor conditions because the motor enclosure helps reduce internal contamination. This can improve motor durability compared with more open motor designs in demanding environments.

For pool professionals, the 354822S provides a direct, reliable motor replacement option for compatible 1 HP single-speed Challenger pump applications.

Compatibility Notes

This motor is intended for compatible Pentair Challenger high-pressure pump applications and other matching 1 HP, 56Y square flange pump setups.

Before ordering, verify:

• Existing pump model and part diagram
• Horsepower rating
• Motor frame size
• Voltage requirements
• Flange style
• Service factor / total horsepower compatibility
• Seal plate and impeller compatibility
• Existing wet-end condition

Do not order by horsepower alone. Pump motors must match the pump’s hydraulic components and electrical requirements.

Installation Notes

This motor should be installed by a qualified pool professional or licensed electrician. Turn off all power at the breaker before servicing the pump.

During installation, inspect the shaft seal, seal plate, impeller, diffuser, pump housing O-ring, bonding wire, electrical connections, and wet-end components. A new shaft seal and related gaskets are strongly recommended whenever replacing a pool pump motor.

After installation, verify correct voltage wiring, bonding, pump rotation, priming, leak-free operation, and normal operating amperage.
