Mechanical Seal ABRB3 (Big Bore)

Mechanical Seal ABRB3 (Big Bore)

Features

  • Rotating design uses centrifugal force for self-cleaning
  • Uniform 360° transfer of torque to the rotating face
  • Welded metal bellows replace the dynamic elastomer which can hang up the seal faces
  • No springs to clog or break
  • No fretting
  • Only two (2) static elastomers – eliminate seal failures caused by dynamic O-ring “hang up” and offers cost savings when upgrading to Perfluorelastomers
  • Monolithic rotating seal ring made from a solid, homogenous material and is easily field-repairable
