SAF V SAP V Burgmann mechanical seals

SAF V SAP V

Features

  • Cartridge design
  • Single seal
  • Balanced
  • Dependent on direction of rotation
  • Integrated pumping device
  • Stationary spring loaded unit
  • Inserted seal face
  • Rotating carbon seat

Advantages

  • Deformation-optimized seal for high sliding velocities and also medium pressures
  • 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 and optimized seat / seal face design
  • Insensitive to shaft deflections due to stationary design
  • Pre-assembled unit for quick and also easy installation
  • Also Only small number of components
