Product Overview

The Pentair 355068 Challenger High Flow pump impeller is a replacement wet end component used in specific Challenger configurations. Pentair’s official replacement parts sheet identifies this SKU as “Impeller, 3F 50 Hz/5F 60 Hz” and places it in the Challenger High Flow pump breakdown with the corresponding diffuser and associated wet end parts. That makes exact part-number matching important during maintenance and repair.

This replacement part is best used when the original impeller has become worn or damaged and the rest of the pump remains serviceable. Because Pentair separates these higher-output Challenger configurations from lower-horsepower impeller groupings in the same parts document, using the correct Pentair 355068 impeller helps maintain proper fit, support normal hydraulic function, and preserve the serviceability of the existing pump assembly.
