Pentair Impeller 7-1/2 HP | CSPH/CCSPH Series Pump | 16830-0209

The Pentair Impeller – 7-1/2 HP (16830-0209) is the OEM replacement impeller for the CSPH/CCSPH Series commercial pump line, engineered specifically for 7-1/2 HP pump configurations.

What It Does

The impeller is the rotating hydraulic component at the heart of the pump, converting motor energy into water flow. A worn or damaged impeller reduces flow rate, strains the motor, and compromises circulation performance across the system. Replacing it with the correct OEM impeller restores the pump to its rated hydraulic output. Match the part number on your existing impeller before ordering to confirm correct fit.

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, locate the part number stamped or molded directly on your existing impeller and confirm it matches 16830-0209. The CSPH/CCSPH Series spans multiple horsepower configurations, each requiring a horsepower-specific impeller — ordering the wrong HP rating is the most common fitment error on this pump line. When the pump is already disassembled for impeller replacement, inspect the shaft seal and wear ring at the same time; replacing these together eliminates the need for a second teardown if either fails shortly after.
