Many of you are more than capable of rebuilding the Nordson® glue pumps. Keystone provides a rebuild kit for the Nordson® ProBlue piston pumps that will set you back a measly $65. If you were to purchase a new one of these, you are looking at dropping a couple of grand. As you are aware, a pump is not complicated. If your job allows you time to perform your own rebuilding, this is the route for you. Keystone provides the same kit as the Nordson® 1028304 kit.
