Benefits

  • The perfect match for hot water applications. The design is tailored to the cooled pump cover.
  • This robust seal is designed for operating conditions with extremely high pressures and temperatures.
  • The solid seal faces abut the metal components and are thus axially secured, which prevents tilting of the seal faces. This ensures reliable sealing and low wear also in extreme conditions.
