PS212
PS212
Advantages
- 100 % compatible with MG12
- 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
Features
- For plain shafts
- Single and dual seal
- Elastomer bellows rotating
- Balanced
- Independent of direction of
rotation
Operating range
- Shaft diameter: d1 = 10 ... 100 mm (0.55" ... 3.94")
- Pressure: p1 = 18 bar (261 PSI), vacuum up to 0.5 bar (7.25 PSI),
up to 1 bar (14.5 PSI) with seat locking
- Temperature: t = -20 oC ... +140 oC(-4 oF ... +284 oF)
- Sliding velocity: vg = 10 m/s (33 ft/s)
- Admissible axial movement: ±2.0 mm (±0,08")
