Pentair 355369Z Pump Impeller
The Pentair 355369Z is a replacement pump impeller designed to restore proper water flow and operating efficiency in compatible Pentair Challenger high-pressure pool pumps. A worn impeller can reduce circulation, strain the motor, and impact overall system performance.
Key Benefits
- Restores proper hydraulic performance and water flow
- Helps reduce motor strain caused by worn or damaged impeller blades
- Precision-molded for correct balance and smooth pump operation
Compatibility
- Designed for Pentair Challenger high-pressure pool pumps
- Commonly used with 1.0 HP full-rated and 1.5 HP uprated motor configurations
Fitment Tip: Always verify pump model, horsepower rating, and service manual before ordering. Impeller size and thread type must match the original component exactly.
