I'm guessing by volute seal you are talking about the O-ring. Yes I replaced that, the wear ring, and the shaft impeller seal. I went ahead and pulled the motor out again. I took it all apart and made extra sure to not let a flake of dust on the seal. They were lined up correctly ceramic to ceramic both times. This time around it seems like it is almost bone dry. I'm going to just let it run like that. I did see a drop or two of water on the wood under the pump, but I'm just not going to worry. I'll check it in a few months and see if it has gotten better or worse. Worst case scenario would be trying to replace the seal one more time and then the entire motor if needed. I can live with it how it is though.
