Try using 2 paper gaskets instead of just 1 to allow for the heat.
This pump is constantly passing raw water and doesn't get warm when the impeller is working. It is a little warm after the impeller fails, but that is after the fact.

Measuring the clearance shows the chamber that is about 1/16" wider than the impeller so I don't think there is any binding in there.
