Pentair Impeller | C Series High Performance Commercial Pump | 073830

The Pentair Impeller (073830) is the OEM replacement impeller for the C Series High Performance Commercial Pump, specifically the 10 HP single-phase and three-phase CH-100, CHK-100, and CHKL-100 high head configurations. The impeller is the rotating hydraulic component that accelerates water outward through centrifugal force, generating the flow and pressure your circulation system depends on. A worn, cracked, or cavitated impeller causes measurable drops in flow rate and system pressure while increasing motor load. Replacing it with the correct OEM impeller restores the pump to its rated hydraulic performance.

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 Impellers are application-specific — thread pitch, bore diameter, and vane geometry must match your pump model exactly. Before ordering, locate the part number stamped or cast on your existing impeller and confirm it matches 073830. The high head designation is critical: high head and standard head impellers are not interchangeable even within the same horsepower rating. If the number on your impeller differs from 073830, cross-reference it against the current Pentair parts diagram for your pump model before purchasing.
