Mechanical Seals

Style 60/61/62/64

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 stainless seal face retainer and 316SS other parts (other special 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 and can be API compliant
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
- Style 66 Single High Temperature Rotating Metal Bellows Cartridge (uses Style 60)

Max Temp - 800ºF (425ºC)
Max Pressure - 300 PSI (20 bar)
Shaft Speeds to - 4500 SFPM (22 m/sec)

Stationary Designs accommodates higher shaft to stuffing box misalignment. Since the bellows only flexes once during installation and not every revolution like a rotating design. This reduces face movement and increases seal life.
- Style 64 Stationary High Temperature Bellows with Grafoil Packing
- Style 63 Single High Temperature Stationary Metal Bellows Cartridge (uses Style 64)

Max Temp - 800ºF (425ºC)
Max Pressure - 300 PSI (20 bar)
Shaft Speeds to - 10,000 SFPM (50 m/sec)
