Pentair Impeller 2 HP | SuperFlo / SuperMax / Challenger High Flow | 355086Z

The Pentair 355086Z is the OEM replacement 2 HP impeller for the SuperFlo, SuperMax, and Challenger High Flow pump lines, covering both single-speed and 2-speed configurations.

What It Does

The impeller is the rotating component inside the pump volute that generates flow by converting motor shaft energy into hydraulic pressure. A worn, cracked, or clogged impeller directly reduces flow rate and system pressure. Replacing it with the correct OEM part restores the pump to its rated performance. Match the part number stamped or molded on your existing impeller before ordering — 2 HP and 1-1/2 HP Full Rated / 2 HP Uprated configurations use this same part across the Challenger High Flow, SuperFlo, and SuperMax families.

Specifications

Fits Into

Compatibility is based on Pentair parts documentation and available OEM records. This is not an exhaustive list. For certainty, verify the part number in your equipment's manual or on the original part itself before ordering.

Pro Tip

Before ordering, locate the part number molded into the existing impeller hub or stamped on the pump's parts label inside the strainer housing lid. The 355086Z covers both single-speed and 2-speed 2 HP configurations across the SuperFlo, SuperMax, and Challenger High Flow families — but HP rating alone is not sufficient to confirm fit. Verify the part number directly. While the pump is open for impeller service, inspect the shaft seal and volute O-ring for wear and replace them at the same time to avoid a second disassembly.
