Don't be too concerned about that ring unless it is leaking. If you do mess with the pump at all, then yes replace it for sure.
I would check that the pulleys are all freely spining and quiet. After that, consider the tension you have and the brand of belt you are using. Is the belt actually glazed or is it simply shreading?
If it is shredding and the pulleys are all fine... are you sure you are tightening the bolt enough on the idler pulley? Not the one that pushes it into place, but the one in middle of the pulley. Also try tightening it with the belt OFF and testing for noise/sieze.
