Mechanical Seals Styles 60/61/62/64

HIGH TEMPERATURE WELDED METAL BELLOWS (UP TO 800°F)

Mechanical Seals Styles 60/61/62/64

Features

  • High temperature sealing solutions
  • Hydraulically balanced seal. Allows the seal to handle more pressure without generating excessive heat at the faces.
  • All metal parts are designed to handle elevated temperatures without any adverse effects. Heat treated AM350 or Inconel 718 bellows. Low expansion alloy seal face retainer and 316 stainless steel other parts. Other material options are available.
  • Static shaft grafoil packing
  • Even 360 degree face loading
  • For higher pressure applications, double ply bellows are available
  • Cartridge Designs are available
  • API 682 Type C Arrangement 1 available
  • Rotating designs are self cleaning using centrifugal force to throw solids away from the seal.
    • Style 60 Rotating High Temperature Bellows with grafoil shaft packing
    • Style 62 Rotating High Temperature Bellows with drive lugs and grafoil shaft packing
    • Style 61 Rotating High Temperature Bellows with perfluoroelastomer O-ring
  • Stationary bellows designs accommodates higher shaft-to-stuffing box misalignment. Unlike a rotating bellows design which flexes on every revolution, the stationary bellows design only flexes during installation. This feature reduces face movement and increases seal life. The Style 64 with grafoil packing is the Flex-A-Seal stationary high temperature bellows design.
