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
Operating range mechanical seal emg1
- Shaft diameter:
d1 = 14 … 110 mm (0.55″ … 4.33″) - Pressure: p1 = 18 bar (261 PSI),
