Mechanical simulations are performed to study the performance of an innovative seal in a gear pump. The problem addressed involves the interaction between the metallic motor shaft and the rubber seal, where continuous operation induces wear and deformation, ultimately leading to fluid leakage.

By developing a digital twin of the pump assembly, we are able to accurately reproduce the insertion of the seal into its housing. To ensure a comprehensive representation, the mechanical behavior of the lip-seal is characterized through dedicated experimental tests, including compression, friction, and contact deformation analyses.
