The mechanism of pumping action caused by axially vibrating one of the seal faces with continuous parallel film thickness is clarified experimentally. The results obtained in the experiment confirm the theory developed in a previous investigation [11 ]. The fundamental design principles of mechanical seals are also described from the viewpoint of this pumping phenomenon.
