SHV-D

Features

  • Dual seal in face-to-face arrangement
  • Cartridge design
  • Balanced
  • Multiple springs arrangement
  • Stationary spring loaded unit
  • Shrink-fitted seal rings
  • Rugged mating rings

Advantages

  • Deformation-optimized seal for high pressures and high sliding velocities
  • Economical due to standardized inner components
  • High flexibility due to adaptation of the connection parts to the pump seal chamber
  • 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
