M461CL
Features
- Cartridge double seal for top entry drives
- For glass lined vessels
- With integrated floating bearing
- Liquid lubricated
- Self-closing on product side
- For stepped and unstepped shafts
- Unbalanced
- Independent of direction of rotation
- Multiple springs rotating
Advantages
- Ready-to-fit and factory-tested units
- The M461CL will remain closed even during pressure variations or pressure reversal. Operation is possible with buffer fluid (p1max = 6 bar (87 PSI)) or pressurized with barrier fluid as double seal.
- The seal can be lifted off the glass-lined flange as a complete cartridge. The sensitive glass lined basic flange remains mounted on the vessel.
- Can be applied at higher pressure and rotating speed than specified by DIN.
Operating range
Shaft diameter:
d1 = 40 ... 125 mm (1.57" .... 4.92")
Pressure:
p1 = vacuum ... 10 bar (145 PSI)
p3 = max. 12 bar (174 PSI)
Temperature:
t1 = -40 °C ... +200 °C
(-40 °F ... +392 °F)
Sliding velocity:
vg = 0 ... 3 m/s (0 ... 9.8 ft/s)
For applications beyond this range, please inquire.
! It should be noted that the extremal values of each operating parameter cannot be applied at the same time because of their interaction.
Materials
Seal faces: Carbon graphite or Silicon carbide, FDA compliant
Seats: Silicon carbide, FDA compliant
