Quick overview

  • Genuine Pentair Factory part 355369Z, also listed under the number 355369.
  • Matched to the horsepower Sized for the 1 HP full rated and 1-1/2 HP up rated Challenger, which are the same motor described two ways.
  • High pressure models This impeller is for the high pressure version of the Challenger, not the standard build.
  • The part that moves the water The impeller is what the motor actually spins, so a worn or blocked one shows up straight away as lost flow.
  • Check for wear at the vanes Impellers thin out and chip at the vane edges, and a cracked vane throws the whole rotating assembly out of balance.
  • Match the number, not the look Challenger impellers of different ratings are very similar in appearance, so go by 355369Z rather than by eye.

Product details

The Pentair 355369Z is the impeller for the high pressure Challenger pump at the 1 HP full rated and 1-1/2 HP up rated size. It also appears in Pentair literature as 355369; both numbers refer to the same part.

Full rated and up rated

The two horsepower figures describe one motor. Full rated and up rated are different conventions for stating output, and a 1 HP full rated motor delivers what a 1-1/2 HP up rated motor delivers. That is why a single impeller covers both, and why the label on your motor may not match the number you searched for.

Ordering the right one

Challenger impellers across the range look much alike, and the high pressure models take their own parts. Go by the part number and the rating on the motor plate rather than by appearance. If the pump is open far enough to change the impeller, it is also open far enough to reach the diffuser, the seal and the locking screw, which are worth inspecting while you are there.

Questions and answers

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

What is the difference between 355369 and 355369Z?
They are the same impeller. Pentair carries it under both numbers, and the Z suffix is how it is most often listed now.
What does 1 HP full rated and 1-1/2 HP up rated mean?
One motor, two ways of stating its output. A 1 HP full rated motor and a 1-1/2 HP up rated motor are the same power, so a single impeller covers both descriptions.
Will it fit a standard Challenger?
This is the impeller for the high pressure Challenger. Check which version of the pump you have before ordering, since the standard models take a different impeller.
How do I tell the impeller is worn?
Flow drops off while the motor still sounds normal. Pull the impeller and look at the vanes: thinning edges, chips or a crack means it needs replacing, and so does anything packed solid with debris that will not clear.
