GRACO SEALANT AND ADHESIVE EQUIPMENT ❚ PUMPS AND PACKAGES
Introduction
There are a number of basic pump styles which are used for transferring sealant and adhesive material. The following
pages detail Graco’s selections for sealant and adhesive transfer. Of course, there are many other possibilities within the
Graco product line, to list every possibility would mean that the catalog you are holding would look more like the
Manhattan phone directory!
What we concentrate on in this document are ram-fed pumps. Ram-fed pumps are used for medium to high viscosity
material. The ram provides force to a follower plate, which in turn drives the material to the pump opening. There are
two basic styles of ram pumps: priming piston pumps and 2-ball pumps. In general, this is how they are applied:
