STANDARD DESIGN

SELF-CENTRALISING DESIGN

  
 
KEY FEATURES OF SELF-CENTRALISING:
  • Elimination of seal offset
  • Elimination of leaks
  • Ease  of installation
  • Reduced assembly time
  • Captive assembly
  
 
TORQUE LOADING

Satisfactory performance of the seal depends on correct torque loading during assembly.  The table indicates recommended figures.

For double sealing, additional torque is generally required.
