Thanks! Very viable way to do this, I know for sure on larger shafts. I worked in petro chem refineries all over the world and about every one had a set up to do just this so I think it was fairly common. Pretty expensive I am told for small shafts. Today I learned about a SKF product called of all things Speedi Sleeves. Bought in the size needed and hammered on the shaft with a simple tool provided. Hardened steel, .011 thick. Only issue for me is it has to be installed on either side of the impeller and if that needs changing in the future (duh!) one has to be removed some how. Jury still out on how to do that but I am researching that because it looks VERY cost effective.oh and no need to use anything but the seals you would use normally. There are you tube vids about how it is done. I’m currently trying to find out who sell them here in the SF Bay Area.in the pic I finally took you can see the score marks on either side of the impeller keyway.
