I have a hayward 3000x series pump; i have a replacement aosmith ST1202, sevice factor 1.3, full rated 2hp motor. what is the correct impellor spx3016 or spx3021? Thanks
Hello Mike - The SP3000X Pump Series with an ST1202 would require the SPX3021C impeller. That impeller will work on Hayward Super II models manufactured since 1990. If your pump is older than that, you’ll need the SPX3020CKIT upgrade.
