The disc springs are able to compensate for the decreasing volume of packing cords by developing additional thrust on the packing lid. When the packing volume drops and the force on the packing lid weakens, the disc springs expand and to large extent compensate for such loss of the packing volume.
  • Although the pressure slightly decreases the preloading on the packing cord is safely above the level of the leakage class.
The sealing of the armatures fitted with the set of disc springs lasts much longer while it is also influenced by the quality of the seal itself and its method of installation.
