Pentair Impeller | MAX-E-PRO Inground Pump | C105-238PBZ

Description

The Pentair C105-238PBZ is the OEM replacement impeller for select MAX-E-PRO inground pumps. This is Item No. 10 in the MAX-E-PRO exploded parts diagram.

The impeller is the rotating component at the heart of your pump’s hydraulic assembly. It draws water through the strainer housing and propels it through the circulation system under pressure. A worn, cracked, or clogged impeller directly reduces flow rate and puts additional load on the motor — replacing it with the correct OEM part restores designed hydraulic performance.

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, confirm your pump’s horsepower rating and service factor — the MAX-E-PRO platform uses different impellers depending on whether the motor is configured for full-rate or up-rate service. An incorrect impeller will not deliver the designed flow rate even if it physically installs. While the pump is open for impeller service, inspect the shaft seal and diffuser O-ring and replace them if there is any sign of wear — addressing all wear items in a single service visit avoids a repeat teardown.
