Quick overview

  • Genuine Pentair Factory impeller 355074Z, matched to the horsepower it was designed around.
  • High flow rating This is the high flow version, so match it to a high flow pump rather than a standard one.
  • 1 HP full rated, 1.5 HP up rated The same impeller covers both ratings, which is why one part number spans several pumps.
  • Wide fitment Listed for Challenger, Pinnacle, SuperFlo and Sta-Rite SuperMax pool and spa pumps.
  • SuperFlo VS date limit For SuperFlo VS pumps, it applies to units manufactured before 6/17/19.
  • Restores lost flow A worn or clogged impeller quietly starves the whole system, and a new one puts the rated flow back.

Product details

The Pentair 355074Z is the genuine high flow impeller rated 1 HP full rated and 1.5 HP up rated. It covers a wide spread of Pentair and Sta-Rite pumps, which is why the same part number turns up in several parts diagrams.

Fitment

Pentair lists it for Challenger and Pinnacle High Flow pool and spa 1 hp full rated and 1-1/2 hp inground pumps, and for SuperFlo and Sta-Rite SuperMax pool and spa 1-1/2 hp pumps. On SuperFlo VS pumps it applies to units manufactured before 6/17/19, so read the date on the motor label rather than assuming.

Match the flow rating

This is the high flow impeller. Pentair builds standard and high flow versions of the same nominal horsepower, and they are not interchangeable if you want the pump to perform the way the label says. Compare the part number on the impeller you are pulling out before you order.

What a worn impeller looks like

Vane edges rounded off, hairline cracks at the hub, or debris packed solid between the vanes. Any of those cut flow without making an obvious noise, so the usual complaint is a slow cleaner, weak returns and a filter gauge sitting lower than normal.

Questions and answers

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

Which pumps take this impeller?
Pentair lists it for Challenger and Pinnacle High Flow pool and spa pumps at 1 hp full rated and 1-1/2 hp inground, and for SuperFlo and Sta-Rite SuperMax pool and spa 1-1/2 hp pumps.
Does it fit a SuperFlo VS?
Only SuperFlo VS pumps manufactured before 6/17/19. Check the date on the motor label before ordering.
What does 1 HP full rated, 1.5 HP up rated mean?
They describe the same impeller against two ways of stating pump horsepower. A pump badged 1 HP full rated and one badged 1.5 HP up rated move comparable water, so they share this impeller.
How do I know my impeller is worn?
Weak returns, a slow vacuum, or a filter gauge reading lower than it used to at the same valve settings. Pull the impeller and look for worn vane edges, cracks or packed debris in the vanes.
