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
Secondary seals and metallic parts acc. to application and customer's requirement.
