Abstract: The Back-Structured Shaft Seal (B3S) [1] was developed to achieve an optimal balance between static and dynamic tightness, thermal and chemical resistance, as well as high reliability and durability for PTFE shaft seals. Structures on the back of the sleeve create an active pumping mechanism in the sealing contact. This paper sums up the results of a stamped version in comparison to the laser engraved version. The stamping process causes significant alterations to the material properties of the seal. All prototypes underwent both static and dynamic tests which demonstrate that the B3S principle can be successfully implemented in a stamped version. However, the design of the structures must take additional influencing factors into account.
