Disaster bushing information
(OP)
I am doing some research into disaster bushings. What I am struggling to find is whether or not they are primarily manufactured by the OEM supplying the seal, or if there are a handful of companies just making these things. Also, if anyone has any info about what these things cost, that would be great.
Thanks.
Thanks.

One other quick thing, out of curiousity, what have you heard about about PEEK disaster bushings? I was not aware of anyone already doing this.
Thanks a bunch!

We have seen some failures associated with disaster bushings, but I believe all of them were really the victim of some other failure; either a bearing failure or an installation error. I have seen solidly mounted brass bushing rub on the sleeve so hard that they collapsed the sleeve onto the shaft and it had to be cut off. I have seen carbon bushings broken, but I think this was a result of incorrect installation or catastrophic bearing failures. So, I don't recall every faulting a disaster bushing for a pump failure.

If I am pulling you off in the wrong direction, please let me know. You have been very helpful, and I don't want to take advantage. It is hard to gauge in text whether people mind being helpful or not. In any case, thank you.

My experience is that disaster bushings are replaced when the seal is replaced and are always supplied by the seal OEM. If the seal is in the cartrige form, the bushing will be included and can be considered integral to the seal assembly. I don't know how you could diagnose a failed disaster busing without having the seal disassembled, which would very likely mean the seal will be replaced.
