M461CL-E3

Features

  • Retrofit for JC Type 109 / Type 109B
  • 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 unit
  • The M481CL-E3 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.
  • Made of stainless steel, no protective coating required

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.
