Pentair Impeller | C Series High Performance Commercial Pump | 073828

The Pentair Impeller (073828) is the OEM replacement high head impeller for the C Series High Performance Commercial Pump, rated for 5HP single-phase and three-phase operation. The impeller is the rotating component at the heart of the pump's hydraulic assembly. It accelerates water through centrifugal force to generate the flow and pressure your system demands. A high head impeller is engineered to produce elevated pressure output — essential for commercial applications requiring water to travel greater distances or overcome significant resistance in the plumbing circuit. When an impeller becomes worn, cracked, or clogged with scale, pump performance drops measurably: flow rates fall, system pressure becomes inconsistent, and the motor works harder to compensate. Replacing the impeller with the correct OEM part restores designed hydraulic performance.

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 the impeller type stamped or molded on your existing part. The C Series pump platform uses different impeller configurations depending on the application — high head and medium head impellers are not interchangeable. Matching the part number (073828) and the "high head" designation to what is currently installed ensures you restore the pump's original hydraulic curve. If you are servicing the pump wet end at the same time, inspect the diffuser and shaft seal for wear — replacing them together avoids a repeat disassembly.
