Pentair 355315Z Pump Impeller

The Pentair 355315Z is a replacement pump impeller designed for use in compatible Pentair Challenger high-pressure pool pumps. A properly functioning impeller is critical for maintaining correct water flow, system pressure, and overall pump efficiency.

Key Benefits

  • Restores proper circulation and hydraulic performance
  • Helps reduce motor strain caused by worn or damaged impeller blades
  • Precision-molded for balanced rotation and smooth pump operation
  • Durable construction for long service life in demanding pool environments

Compatibility

  • Designed for Pentair Challenger high-pressure pool pumps
  • Commonly used on pumps with 1.5 HP full-rated motors
  • Also compatible with select 2.0 HP uprated configurations

Fitment Tip: Always verify pump model and horsepower before ordering. Impeller size and thread type must match the original impeller exactly.

What’s Included

  • 1 × Pump impeller (Pentair 355315Z)

Installation Notes

  1. Shut off power to the pump at the breaker.
  2. Relieve system pressure and drain the pump housing.
  3. Remove the diffuser and unthread the existing impeller from the motor shaft.
  4. Inspect the shaft seal and diffuser for wear and replace if necessary.
  5. Thread the new impeller onto the shaft and reassemble the pump.
  6. Prime the pump and verify proper operation after restoring power.

When to Replace

  • Noticeable drop in water flow or pressure
  • Visible wear, cracking, or erosion on impeller vanes
  • Unusual noise, vibration, or overheating during pump operation

Maintenance Tips

  • Clean pump and skimmer baskets regularly to prevent debris from reaching the impeller.
  • Inspect the impeller whenever the pump is opened for seal or gasket service.
  • Replacing the shaft seal at the same time helps prevent leaks and extends motor life.
