Pentair Impeller, 1/2 HP | Dyna-Pro / Dyna-Pro E | C105-236P

The Pentair Impeller, 1/2 HP (C105-236P) is the OEM replacement impeller for 1/2 HP Dyna-Pro inground pump models.

What It Does

The impeller is the rotating component inside the pump wet end that generates flow by converting motor energy into hydraulic pressure. A cracked, worn, or clogged impeller reduces flow rate and puts additional load on the motor. Replacing it with the correct OEM impeller restores designed flow performance. Match the part number on your existing impeller before ordering — impeller sizing is horsepower-specific and an incorrect HP rating will not deliver the flow your system requires.

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

When replacing the impeller, inspect the diffuser and shaft seal at the same time. These components wear together, and replacing all three during the same service interval avoids reopening the pump wet end for a second repair shortly after. Confirm your pump's horsepower rating on the motor nameplate before ordering — the 1/2 HP impeller (C105-236P) is not interchangeable with impellers rated for other horsepower configurations in the Dyna-Pro line.
