Features mechanical seal cgsh-k
- For stepped shafts
- Balanced
- Rotating spring
- Single or double seal available
- Standard version with U-grooves, V-grooves optional (dependent of direction of rotation)
- Gas-lubricated
- Does not open in the event of buffer pressure failure, self closing at pressure reversal
Advantages mechanical seal cgsh-k
- Contact-free operation, no friction
No differential - pressure required with hard/soft material
- combination
- Applicable as containment seal acc. to API 682
Operating range mechanical seal cgsh-k
