Advantages

Deformation-optimized seal for high pressures and high sliding velocities (static up to 500 bar (7,250 PSI))and dynamic up to 150 bar (2,175 PSI))
Economical due to standardized inner components
High flexibility due to adaptation of the connection parts to the pump seal chamber
Optimum heat dissipation due to integrated pumping device
Insensitive to shaft deflections due to stationary design
Dual seal does not open even in the event of barrier fluid pressure failure
Reliable operation due to one rugged seat with bandage
Version with loose-fitted seal face available, for extreme applications
Only small number of components
