Technical Data

  • Operating pressure: Up to 110 bar                                  
  • Temperature: Up to 320°C


Especially designed for operating conditions with extremely high pressures and temperatures. The design is tailored to the cooled pump cover.

The solid seal faces abut the metal components and are thus axially secured. This prevents tilting of the seal faces. This ensures reliable sealing and low wear also in extreme conditions.

The special design with hook sleeve does away with the need for an axial adjusting dimension; the seal is always perfectly positioned on the pump shaft.
