WEMG1 rubber bellow mechanical shaft seal for water pump
Features
For plain shafts
Single and dual seal
Elastomer bellows rotating
Balanced
Independent of direction of rotation test
Advantages
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
Recommended applications
