The pump packing gland has been repeatedly tightened by small increments until the gland has bottomed. Which of the actions listed should be carried out next if the leakage continues to be excessive?
• Stuffing box / pump packing gland function and how it controls leakage • What it means when a packing gland has bottomed out (no further adjustment left) • Proper maintenance practice when adjustment is exhausted but leakage is still excessive
• If the gland is already fully tightened and leakage is still excessive, what does that say about the condition of the existing packing? • Would using larger or more packing turns fix the underlying problem, or could it damage the shaft or stuffing box? • Which option reflects a proper, standard maintenance procedure versus a temporary or improper workaround?
• Confirm that a bottomed-out gland means there is no more mechanical travel left for further compression of the existing packing. • Think about whether changing the size or type of packing (without addressing the old packing condition) is recommended practice. • Remember that good practice is to restore proper packing arrangement and clearances, not just force more material into the stuffing box.
