Benefits

  • Single mechanical seal, tailored to the seal installation space and the operating conditions of the submersible mixer
  • Stationary, balanced design. The multi-spring arrangement is located outside the fluid handled in the oil reservoir. Thus, the springs are insensitive to contamination and provide uniform surface pressure across the seal faces, ensuring a long service life.
  • Suitable for all fluids with a high solids content and those containing long fibres
