Product details

The Pentair 353323 is the diffuser screw for WhisperFlo XF pumps. The same screw is used on IntelliFlo XF VSF and IntelliFlo XF VS pumps manufactured after August 2015.

What it holds

The diffuser sits over the impeller and directs water into the volute. This screw is what keeps it located. It is a small, inexpensive piece, and it is also the piece people find corroded or missing when a pump that should be moving water is not moving much of it.

Order by number

Pump hardware looks alike across models. Ordering by 353323 is how you get the XF screw rather than something similar from another Pentair pump.

Questions and answers

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

Which pumps use this screw?
Pentair WhisperFlo XF pumps, and IntelliFlo XF VSF and IntelliFlo XF VS pumps manufactured after August 2015.
Will it fit an older IntelliFlo XF?
The listing covers XF pumps built after August 2015. On an earlier pump, check the part number against your own parts list first.
Why replace the screw?
It holds the diffuser in place. A corroded or missing screw lets the diffuser shift, and the pump loses flow.
Is it a genuine Pentair part?
Yes. It is Pentair part 353323.
