Gland Seal vs. Mechanical Seal | Difference Between the ...

Packing seals use rope-like materials that wrap around the shaft of a pump, filling in dead space and minimizing fluid loss. Over time, however, fluid loss will increase as the gland packing material begins to wear down and may impair regular lubrication or reduce ease-of-replacement that is required to function properly.
