Barnwell Services Mechanical Seals are one of the most effective ways of sealing rotating shafts, consisting of two lapped faces arranged perpendicular to the axis of the rotating shaft (which gives rise to the alternative name Radial Face Seal, Pump Seals or Packings).
One face is fixed to the equipment casing or vessel, while the other is fixed to the shaft and so rotates with it. Frictional heat generation and wear are controlled by maintaining a film of lubricant between the seal faces. As such, mechanical seals resemble thrust bearings.
