Abstract
A system and method of manufacturing improved wear ring assemblies and positive pressure shaft seals. The wear ring assemblies are made from stacked layers of flat metal. Different shaped component parts of the wear ring assemblies are cut from various sheets of metal. The component parts are stacked to form different sections of the wear ring assemblies. The stacked component parts are welded or otherwise bound together. The resulting sections of the wear ring assemblies are then assembled to form the annular structure of a full wear ring assembly. The result is a wear ring assembly that is both easy and inexpensive to produce.
