Quick overview

  • Sta-Rite C105-238PDCA The number to match when ordering an impeller by rating.
  • 1.75 HP up rate Impellers are cut to a horsepower rating, and the rating has to match the pump.
  • Build date matters Listed for SuperFlo VST pumps manufactured after 6/17/19.
  • Restores flow A worn or blocked impeller shows up as weak returns and lazy skimming.
  • Not interchangeable by eye An impeller of the wrong rating can still fit the shaft and move the wrong volume.
  • Check the neighbors The impeller screw, impeller o-ring and diffuser are separate parts worth inspecting while the wet end is open.

Product details

The Sta-Rite C105-238PDCA is a replacement pool pump impeller rated 1.75 HP up rate. It is listed for SuperFlo VST pumps manufactured after 6/17/19.

Why the rating and the date both matter

An impeller is machined for one horsepower rating. Fit the wrong one and it may still slide onto the shaft while moving the wrong volume of water, which either starves the returns or loads the motor. The build date is the other half of the check: this part covers SuperFlo VST pumps built after 6/17/19, so confirm the date on your pump before ordering.

While the wet end is open

The impeller screw, the impeller o-ring and the diffuser sit right behind the impeller and are separate parts. They are worth inspecting while everything is already apart, since a fresh impeller behind a tired diffuser will not give back the flow you are chasing.

Questions and answers

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

Which pumps does this impeller fit?
It is listed for SuperFlo VST pumps manufactured after 6/17/19. The build date matters, because the impeller changed.
What does up rate mean?
It describes how the horsepower is stated for the pump the impeller belongs to. Order the impeller that matches your pump rating, in this case 1.75 HP up rate.
Can I fit a different horsepower impeller?
No. The impeller is matched to the motor. A mismatched impeller will load the motor wrongly or move less water than the pump was designed to.
What else should I replace at the same time?
With the wet end open, look at the impeller screw, the impeller o-ring and the diffuser. They are cheap and they are already exposed.
