DF-SA DiamondFace

Features

  • Cartridge design
  • Single seal
  • Balanced
  • Integrated pumping device
  • Stationary spring loaded unit

  • Rotating mating ring
    (DiamondFace coated)

Advantages

  • Resistant to electrochemical corrosion.
  • Extremely long service life (>40,000 h).
  • No dosing system, no cooling circuit conditioning required.
  • Diamond coating provides very low friction, thus reduced power consumption.
  • Deformation-optimized for high sliding velocities and medium pressures.
  • Economical due to standardized 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.
