the rotor becomes considerably spaced from the stationary seal ring. The frictional engagement of the secondary seal O-ring prevents the seal ring from tracking the rotary seal ring, and thus from closing this gap. This problem is exacerbated when the mechanical seal is shut down, and the : rotor ax

โฆ Synopsis
This patent uses torque transfer pins that are manufactured from memory metal. The purpose of this is to reduce wear and breakage of the torque transfer mechanism in the seal. In the event of excessive torque, such as during startup, the memory metal can withstand the additional superelastic strain, from which it will subsequently recover. Wear or breakage of the drive pins is therefore reduced compared to a seal with conventional pins.
