Product details

The Pentair 356238Z is the diffuser assembly for the IntelliFlo 3.0 Energy Star variable speed pump. The diffuser sits around the impeller inside the wet end and guides water from the impeller into the pump housing, so a worn or cracked one costs you flow even when the motor and impeller are fine.

This is the genuine Pentair part, supplied as a complete assembly ready to fit. It is specific to the IntelliFlo 3.0, so check the model label on your pump before ordering.

If you are rebuilding the wet end, the matching IntelliFlo 3.0 impeller assembly is sold separately and is usually replaced at the same time.

Questions and answers

What people ask about this product, answered by our pool techs.

Which pump is this for?
The Pentair IntelliFlo 3.0 Energy Star variable speed pump. Confirm your pump is the 3.0 before ordering, since earlier IntelliFlo generations use different wet end parts.
Does the impeller come with it?
No. The IntelliFlo 3.0 impeller assembly is a separate part. Many rebuilds replace both at once.
When should a diffuser be replaced?
When it is cracked, when the opening around the impeller has worn oversize, or when flow has dropped and the impeller itself checks out.
Is this a genuine Pentair part?
Yes. Pentair part 356238Z, UPC 788379502546.
