Product details

The Val-Pak V38-132 is a replacement diffuser for the Pentair American Products Ultra-Flow pool pump. One part covers the 0.5 HP through 1.5 HP models.

What the diffuser does

Inside the wet end, the impeller throws water outward and the diffuser is the shaped housing that catches it and turns that motion into usable pressure. When the diffuser is cracked, worn at the eye, or no longer sealing against the impeller, water slips back around instead of going out to the filter. The pump sounds normal, the motor draws normal current, and the pressure is simply down.

Ordering notes

This is a Val-Pak aftermarket part, not a factory Pentair one, made to the same fitment. Unlike the impellers, which are matched to a specific horsepower, this diffuser is listed across the half through one and a half horsepower Ultra-Flow range. If the impeller is scored or the vanes are worn, replace both while the wet end is open.

Questions and answers

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

Does one diffuser really cover all those horsepowers?
Yes. V38-132 is listed for the 0.5 HP through 1.5 HP Ultra-Flow pumps. It is the impeller that changes with horsepower, not the diffuser.
Is this a genuine Pentair part?
No. It is a Val-Pak replacement diffuser made to fit the Pentair American Products Ultra-Flow pump.
Which pump is this for?
The Pentair American Products Ultra-Flow.
Should I change the impeller at the same time?
It is worth a look. The diffuser runs right against the impeller, so if one is worn the other often is. Ultra-Flow impellers are sold separately and are matched to horsepower.
