Mechanical Seal Style 63

Single High Temperature Stationary Welded Metal Bellows Cartridge Seal

Mechanical Seal Style 63

Features

  • Easy cartridge seal installation of the Style 64 stationary high temperature bellows
  • Proven high performance nesting ripple bellows design
  • High temperature static grafoil packing throughout seal
  • Standard AM350 heat treated bellows with Inconel 718 heat treated bellows option available
  • Low expansion alloy face retainer
  • Stationary design accommodates higher shaft-to-stuffing box misalignment. The stationary bellows design only flexes once during installation unlike a rotating design which flexes on every revolution. This reduces face movement and increases seal life.
  • Upgradable to API design specifications with piloted gland and metal-to-metal confined gland gasket which prevents blow out or extrusion of the gasket
  • Flush, quench and drain connections with a throttle bushing
  • Bronze steam deflector option available to provide quenching to the inside of the bellows to prevent coke buildup
  • Carbon floating bushing option available
  • API 682 Type C Arrangement 1 available
  • Double-ply bellows core available for higher pressure
