Edge Welded Metal Bellows - For High Temperatures
Up to 800°F

Mechanical Seal Styles 60/62/64/65

HiTempBellows-2018.tif

FEATURES:

  • High temperature sealing solutions

  • Hydraulically balanced seal with even 360 degree face loading. Allows the seal to handle more pressure without generating excessive heat at the faces.

  • All metal parts are designed to handle elevated temperatures without adverse effects: heat treated AM350 or Alloy 718 bellows, low-expansion alloy seal face retainer, and 316 stainless steel hubs and housings. Other material options are available.

  • Static shaft grafoil packing

  • For higher pressure applications, double ply bellows are available

  • Cartridge designs are available

  • API 682 Type C Arrangement 1, 2, and 3 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 64 stationary bellows design 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. 

SPECIFICATIONS:
