Pentair 354813S WhisperFlo XF Replacement Motor | 5 HP | 3-Phase | TEFC | 208–230/460V | Almond
The Pentair 354813S is an OEM square-flange replacement motor designed for select Pentair WhisperFlo XF high-flow pump applications. This is a heavy-duty, totally enclosed fan-cooled (TEFC) motor built for demanding commercial and high-performance pool systems where three-phase power is available. Replacing a worn or failed motor restores reliable starting, smooth operation, and full-flow performance.
Compatible Applications
- Pentair WhisperFlo XF 5 HP pump configurations that use a 3-phase TEFC square-flange motor
- Commercial/high-flow circulation or water-feature systems using WhisperFlo XF-style power ends (model/revision dependent)
Always verify compatibility using your pump model number and parts diagram, and confirm the motor label matches your required voltage and phase.

Common Symptoms a Motor Replacement Can Solve
- Motor will not start, runs intermittently, or trips protection devices
- Overheating, abnormal fan noise, or repeated thermal shutoff
- Grinding/squealing bearings or excessive vibration
- Reduced performance after confirming the wet end (impeller/diffuser) is in good condition
- Visible corrosion, burnt odor, or evidence of electrical damage
Installation Notes
- Turn off power at the breaker/disconnect and verify power is off before servicing.
- Confirm your supply matches 3-phase requirements and the motor is wired for the correct voltage (208–230V vs 460V).
- When swapping motors, it is strongly recommended to replace the mechanical shaft seal and any disturbed O-rings/gaskets.
- Inspect the seal plate, diffuser, and impeller for heat damage if the pump has run dry.
- After reassembly, prime the pump fully and check for leaks at the seal plate and plumbing connections.

Maintenance Tips
- Keep the equipment area ventilated and clear of debris so the motor fan can move air freely.
- Address wet-end leaks immediately—water intrusion and corrosion can shorten motor life.
- Maintain good flow (clean baskets/strainers and filters) to reduce load and heat.
- Confirm proper bonding/grounding and stable supply voltage; electrical issues can damage pump motors.
- If the system is in a harsh environment (salt air, chemical storage nearby), rinse exterior surfaces periodically and reduce chemical splash exposure.
