  • Integrated pumping device
  • Stationary spring loaded unit
  • Multiple springs arrangement
  • Shrink-fitted seal face
  • One rugged seat

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
