About This Item
The Pentair Diffuser Assembly (072927Z) is the OEM replacement diffuser for WhisperFlo WFE-2 through WFE-8 inground pumps (1/2 HP to 2-1/2 HP) and the IntelliFlo i2 Variable Speed Pump.
The diffuser channels water from the impeller eye into the volute, converting velocity into pressure that drives flow through your filtration system. A cracked or worn diffuser disrupts this conversion, resulting in reduced flow rates, increased energy draw, and premature wear on the impeller. Replacing the diffuser assembly restores the hydraulic efficiency the pump was designed to deliver.

Pro Tip
While the pump wet end is disassembled for diffuser replacement, inspect the impeller and shaft seal at the same time. These components share the same service interval and accessing them requires the same disassembly steps — replacing them together avoids a second teardown shortly after. Confirm the part number molded on your existing diffuser matches 072927Z before ordering, particularly if your pump has been repaired previously.
