  • Optimal alignment characteristic through self-cleaning of disk/shaft
  • Improved centering across entire pressure operating range
  • No torsion on bellows
  • Shaft protection over entire seal length
  • Protection of seal face during installation due to special bellows design
  • Insensitive to shaft deflections due to large axial movement ability
  • Suitable for low-end sterile applications
  • Dimension adaptions and additional seats available
