Pentair Impeller, i2 Pump | IntelliFlo i2 Variable Speed Pump | 073131A

The Pentair Impeller (073131A) is the OEM replacement impeller for the IntelliFlo i2 Variable Speed Pump. If your i2 pump has lost flow, is running louder than normal, or the impeller has become damaged or worn, this is the exact replacement component for that pump.

The impeller is the rotating component inside the pump volute responsible for moving water through your circulation system. When an impeller is cracked, clogged beyond cleaning, or worn, flow rate drops and the pump motor works harder to compensate. Replacing it with the correct OEM part restores the pump to its rated hydraulic performance. Match the part number 073131A to the number molded on your existing impeller before ordering this impeller is designed specifically for the i2 model and is not interchangeable with other IntelliFlo variants.

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 disassembly, photograph the existing impeller orientation and note the direction of the vanes reinstalling the replacement in the correct orientation is critical to restoring proper flow. While the pump is open, inspect the shaft seal and diffuser for wear and replace them at the same time if needed, as these components share the same service interval and accessing them again later requires the same teardown.
