Hayward SPX3021R Impeller Ring Replacement for Select Hayward Tristar, Northstar and Super Ii Pump

Perfect fit for my Hayward Tristar 3/4hp pool pump & skimmer housing. Easy to replace. It may have been a much better quality part than original, I'm not sure as the part I removed was worn so badly it was about half the size in thickness.TIP: GASKET LUBE, A SOCKET SET & RUBBER BELT WRENCH USUALLY INTENDED FOR OIL FILTER REMOVAL is what you will need to replace this part.I removed/unscrewed the 2" pvc pipes off the skimmer housing and from there removed the 6 housing to pump bolts. Slid the skimmer housing away from the pump and removed the 2 Phillips screws from the impeller. The pvc gasket/seal is placed between the 2 halves of the impeller after sliding the 1st half off you'll find this white pvc gasket which is intended to absorb any friction created between both impeller halves as the pump runs. It's an easy fix. I knew mine was ready to be replaced as it was making a clicking noise while pump was running, which sounded like something had been caught inside the pump itself, almost like a twig or pebble. The noise was actually made by the old pvc gasket having snapped in half.PLEASE NOTE: If you appreciated this review please give it a “thumbs up/like” your helping me to continue to give honest/unbiased insight into products I’ve used and you may have questions about. Interested in a product but don't know enough about it and would like it reviewed? Please let me know and I'll see what I can do... Thank you 🙏

It is what it is.

It fit and worked well.

Perfect fit. So glad I ordered via AMAZON!

Not much to say here -- it's a replacement part and if yours is worn this is what you need. Replacing the wear parts in a pool pump head is a LOT cheaper than replacing the pump, and has the same effect -- you have a pump that performs exactly as a new one does!

Working well after a few months. The previous ring cracked into multiple pieces and partially clogged the impeller. Result was a loss of pressure that I could never fix or figure out until I opened up the pump. It becomes brittle after many years usage running, so its good to replace periodically probably w each motor replacement.

I rebuilt my Ecostar pump to take it down from a Variable Speed to a 2-speed (Tristar) pump. The original impeller ring is supposed to work for both models but the one that I had in the Ecostar was the wrong size by a wide margin. My EcoStar which had a faulty drive must have been built on a Friday or something.This one fits like a glove and is ready for use. The diffuser is now on and just the 2 o-rings and the 6 bolts and an electrical hook up remains.

Pool pump primes now. Old part was scored and damaged by sand, and was jammed by sand on impeller so that it could not seat and seal like it was supposed to do. Good as new now.
