Split from Cracked Diffuser?There are 2 different rings.
For Impeller SPX3005C, SP3007C, SP3010C, use ring number SPX3005R;
For Impeller SPX3016C or above, use ring number SPX3021R.
The part numbers should be stamped on the ring and the impeller.
Based on the diffuser part number of SPX3000BN, the ring should be SPX3005R. I suspect that you have the wrong ring.
