Advantages mechanical seal sh(v)

  • 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
  • Insensitive to shaft deflections due to stationary design
  • Pre-assembled unit for quick and easy installation
  • Suitable for use in compliance with API 682, type ES
  • Version with loose-fitted seal face available, for extreme applications
  • Only small number of components
