When the one on my dad's 97 PSD failed, it was the bearings. They wore down, finally overheated and blew the caps off the outside of the bearings. It must have been going for a long time because the new one provided so much more vacuum that he would nearly lock the brakes every time he stopped.

Maybe you're getting some type of contamination in the lines thats damaging the pump? Does it use brake fluid? Pull the line off the booster and check for fluid.

Not sure what makes it fail but I replaced mine on 1991 F250HD Last month and it's producing about 25 inches of vacuum I think thats what it tested at.

Any REPUTABLE shop would offer you some technical explanation.
Did you save any of the broken pumps?
