Fluid sealing technology is based on many disciplines as diverse as fluid Mechanics,
lubrication, friction, wear, heat, transfer, properties of materials and mechanical design.
The physical processes in the seal interface are governed by molecular interaction,
geometry of seal faces, and Proper balance of forces; By heat conduction, heat transfer
and phase changes and by material properties. Some time the interrelation of influences
is of such complexity that straightforward analytical calculations are not sufficient to predict the operational behavior of a seal. For example, liquid viscosity varies with temperature, which varies with fractional heating, which varies with face separation, which varies with viscosity!

Leak - Proof Engineering has computer programs to predict the seal behavior. Finite element analysis of seal components is carried out for strength and deformation analysis. Further, seal testing is carried out to ensure the performance.
