If you have replaced the seal multiple times and it is stil leaking sounds your pump needs more than a seal. I would guess worn seal area on the shaft and/or possibly worn bushings that allow the shaft to wobble taking the seal out.

If replacing the seal is not correcting the problem I'll agree with Dan, it may be time to replace the pump.

Thank you for the help. The shaft was scored so I cleaned it up and swapped the bushing for one that was tighter and it works great now.
