ANSI Dual Tandem Rotating Welded Metal Bellows Cartridge Mechanical Seal



Product Line Features

  • Simple cartridge seal installation.
  • Sleeve is isolated from process fluid.
  • 3/8” NPT barrier connection allows for cooling.
  • Vantage tandem seal glands include four (4) barrier in and out connections for maximum piping flexibility.
  • Angled gland connections allow for easier pipe fitting.
  • Setting clips provide positive axial and radial setting of the Vantage cartridge seal to ensure proper seal installation. The Vantage setting clips are easy to access for simple removal.
  • Only one Allen wrench required to tighten screws and remove the setting clips.
  • Convertible gland design to accept over twelve (12) design configurations.


  • 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
  • Static elastomers – eliminate seal failures caused by dynamic O-ring “hang up” and offers cost savings when upgrading to Perfluorelastomers
  • Available in ANSI Big/Taper and Standard Bore
