OEM Mechanical Seal


Features

• For top entry drives, type M481 to DIN
• Single or double seals
• Unbalanced
• Independent of direction of rotation
• Multiple springs rotating
• Liquid-lubricated
• Cartridge unit


Operating range

Single seals:
Pressure: p1 = vacuum ... 6 bar (87 PSI), p3 = pressureless
Temperature: t1* = –40 °C ... +150 (250) °C (–40 °F ... +302 (482) °F)

Double seals:
Pressure: p1 = vacuum ... 16 bar (232 PSI), p3 = max. 18 bar (261 PSI)
Temperature: t1* = –40 °C ... +200 (350) °C (–40 °F ... +392 (662) °F)


Sliding velocity: 0 ~ 5 m/s (0 ~ 16 ft/s)

For applications beyond this range, please inquire.
* Higher or lower temperatures on request.

• Reactors


Product variants


M481K
Single seal


M481KL
Single seal with integrated floating bearing.
Operation of single seals only with pressureless quench.

M451
All types of the M481 range available for unstepped shafts (all diameters). Seal identification: M451 ... Customized design or e. g. different drives (torque transmissions) are available.

M481K-D
Double seal

M481KL-D
Double seal with integrated floating bearing.
These seals are designed to be self-closing on the product side, i.e. they will remain closed even with pressure variations or a pressure reversal. Operation is optionally the same as for the single version (p max = 6 bar (87 PSI) or Δp max = 6 bar at p 1 > p 3 ). In view of the mechanical seal on the atmosphere side it can be used as a buffer pressurized double seal p 1 = 16 bar (232 PSI).
