About This Item

The Pentair Diffuser (072928Z) is the OEM replacement diffuser for WhisperFlo and IntelliFlo variable speed pumps. Confirm the part number molded into your existing diffuser before ordering to verify correct fit.

⚠️ IMPORTANT: MANUFACTURED BEFORE 10/2020 PUMPS ONLY
This diffuser is designed for WhisperFlo and IntelliFlo pumps manufactured before October 2020. Pumps built after this date require a different diffuser assembly. Check the manufacture date label on your pump before ordering.

The diffuser channels water from the impeller into the pump's volute, converting rotational velocity into pressure. A cracked or worn diffuser reduces hydraulic efficiency, causes loss of prime, and can allow cavitation that accelerates wear on the impeller and seal. Replacing this part restores the pump's designed flow performance. Match the part number molded into your existing diffuser before ordering to confirm correct fit.

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

When the pump is open for a diffuser replacement, inspect the shaft seal and impeller for wear at the same time — these components share service intervals and replacing them together avoids a second teardown. Also confirm your pump's manufacture date label before ordering: this diffuser fits pumps built before October 2020. Pumps built after that date require a different assembly.
