Quick overview

  • High flow version This is the high flow impeller, not the standard one, so the pump model has to match.
  • Two ratings, one part Covers 2 HP full rated and 2-1/2 HP up rated pumps, which are the same hydraulic size.
  • Genuine Pentair Factory part 355093Z, the same impeller fitted originally.
  • SuperFlo, SuperMax and Challenger Used across the Pentair SuperFlo, SuperMax and Challenger High Flow pumps.
  • Restores head and flow A worn impeller loses pressure gradually, so the drop is easy to miss until the cleaner or heater starts complaining.
  • Replace the seal with it The mechanical seal rides behind the impeller, and both come off in the same teardown.

Product details

The Pentair 355093Z is the high flow impeller for 2 HP full rated and 2-1/2 HP up rated pumps in the SuperFlo, SuperMax and Challenger High Flow families. It is the genuine Pentair part.

Full rated or up rated

Those two labels describe the motor rating, not the wet end. A 2 HP full rated pump and a 2-1/2 HP up rated pump move the same water and share this impeller. What does matter is high flow versus standard: this is the high flow part, so confirm your pump model rather than working from horsepower alone.

What a worn impeller looks like

Impeller wear is gradual, so few owners notice the flow going. It usually turns up somewhere else: a pressure side cleaner that has gone slow, a heater cycling on flow, a longer time to prime, or a filter pressure reading that has quietly dropped. Vanes that are eroded, chipped or packed with debris all produce the same result.

While the pump is open

The mechanical seal sits directly behind the impeller and comes out in the same teardown, so replace it at the same time. The impeller locking screw and the matching high flow diffuser are available separately if either is damaged.

Questions and answers

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

Which pumps take this impeller?
Pentair SuperFlo, SuperMax and Challenger High Flow pumps in the 2 HP full rated or 2-1/2 HP up rated size.
What is the difference between full rated and up rated?
They describe how the motor is rated, not the impeller. A 2 HP full rated pump and a 2-1/2 HP up rated pump use the same impeller, which is this one.
Is this the high flow impeller?
Yes. It is the high flow version. Standard flow models of the same horsepower use a different Pentair part, so check your pump model before ordering.
What else should I order with it?
The mechanical seal assembly, since it sits directly behind the impeller. The impeller locking screw and matching diffuser are also available separately.
