Product details

The Pentair 73831 is the impeller for the 15 HP three phase HH C Series pump, a genuine Pentair pump part.

Getting the right impeller

Impellers on commercial pumps are matched to the horsepower of the motor turning them, so the 15 HP designation is not a suggestion. Check the horsepower on the motor nameplate and the impeller code cast into the part you are removing before ordering, since the C Series covers a wide horsepower range with a different impeller at each step.

While the pump is apart

This listing is the impeller by itself. The mechanical seal, the o-rings and any wear ring are separate parts. A pump this size takes real work to open, so plan on refreshing the seals at the same time rather than going back in later.

Questions and answers

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

Which pump does this fit?
It is listed as the impeller for the 15 HP three phase HH C Series pump. Confirm the horsepower and the impeller code on your pump before ordering.
Can I use it on a smaller pump in the same family?
No. Impellers are matched to the horsepower of the motor driving them, so a 15 HP impeller goes on a 15 HP pump only.
Does it include the mechanical seal?
No. This listing is the impeller alone. Replace the mechanical seal at the same time, since the pump has to come apart either way.
Is it a genuine Pentair part?
Yes. It is Pentair part number 73831.
