The Pentair Impeller (070227) is the OEM replacement medium head impeller for the C Series High Performance Commercial Pump at 7-1/2 HP, compatible with single-phase and three-phase motors across the CM-75, CMK-75, and CMKL-75 models.
The impeller is the rotating hydraulic component at the heart of the pump's wet end. It draws water through the suction port and accelerates it outward through centrifugal force, generating the flow and pressure the circulation system depends on. A worn, cracked, or clogged impeller reduces flow rate and puts additional load on the motor. Replacing it with the correct OEM part restores the pump to its rated hydraulic performance. Match the part number stamped or molded on your existing impeller before ordering — medium head and high head impellers for the same horsepower are not interchangeable.

Pro Tip
The C Series pump is available in medium head and high head configurations — and both are available at 7-1/2 HP. These impellers are not interchangeable. Before ordering, confirm your pump model suffix and check whether "MED HD" or "HIGH HD" appears on the pump nameplate or the original impeller. Part number 070227 is the medium head version only.
