Benefits

  • The seal is tailored to the seal installation space of the pump and therefore perfectly suitable for fluids with a high solids content.
  • Stationary design; multiple springs located outside the fluid handled The large springs are insensitive to contamination and provide uniform surface pressure across the seal faces, thus ensuring a long service life.
  • Can optionally also be operated with unpressurised buffer fluid
