Is there any way to help prevent this from happening?
The hole where the gear shaft mounts into has rounded out. This was the same thing that happened to my last pump. This pump is about 10 months old.
Are you using solvent ink?
seems like a design flaw for sure. i figure make sure there's lots of packing grease on the interior tube. also, start rebuilding instead of replacing.
try cmykparts.comWhat is needed to rebuild this pumps. And if parts are needed where do you get them.

I believe this is happening because the inks(solvent based inks) are attacking the plastics. It's a chemical reaction. Actually, the plastic is "melting".
