Features

  • Rotating bellows seal
  • Balanced
  • No dynamic O-Ring, no hang-up, no shaft sleeve damage
  • Uniform seal face loading
  • Independent of direction of rotation
  • Ideally suited for highly corrosive and abrasive media
  • Compact design

Advantages

  • Over 35 years of running reference in the field
  • Narrow cross-section allows the seal fitment in narrow stuffing boxes
  • Self cleaning, non-clogging design
  • Cost effective solution for corrosive and abrasive media
  • Long seal life
