Non Compression packing compared to conventional packing

NON COMPRESSION PACKING

  • Low wear and tear on shafts and sleeves
  • Low cost of ownership
  • Less down time
  • Lower power consumption
  • Can seal on a worn shaft
  • Non compression packing
  • Large temperature ranges
  • Good chemical resistance on all packing’s
  • Most applications are leak free
  • Can run dry without burning
  • Long life without constant adjustment
  • Elasticity in packing allowing it to return to original shape
  • Low friction co-efficient
  • Low heat generation
  • Low brake effect
  • Non abrasive
  • Seals equally on all the packing rings throughout the full length of the stuffing box
  • Can operate with no gland load

CONVENTIONAL PACKING

  • High wear and tear on shafts and sleeves
  • High cost of ownership
  • Frequent periods of down time
  • Increased power consumption
  • Requires a straight / new shaft
  • Compression Packing
  • Limited temperature ranges
  • Limited chemical resistance on most packings
  • Always has a leak
  • Cannot run dry
  • Constantly have to adjust to limit the leak
  • Once compressed it does not return to original shape
  • High friction co-efficient
  • High heat generation
  • High brake effect
  • Abrasive
  • Seals on the outer two or three rings only and the remaining rings have very limited sealing effect
  • Requires a gland load
