eMG1 seal
eMG1 seal

Features mechanical seal emg1

  • For plain shafts
  • Single and dual seal
  • Elastomer bellows rotating
  • Balanced
  • Independent of direction of rotation

Advantages mechanical seal emg1

  • 100 % compatible with MG1
  • Small outer diameter of bellows support (dbmin) enables direct retaining ring support, or smaller spacer rings
  • 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
