Advantages seal shf(v)-d / shp(v)-d
- 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
