Many solid packed stuffing boxes have a packing gland for what purpose?

• A. To enhance pump efficiency
• B. To create a vacuum seal
• C. To adjust and reduce the amount of leakage
• D. To control fluid temperature

Answer: (C)

The purpose of a packing gland in solid packed stuffing boxes is to adjust and reduce the amount of leakage. In applications where a shaft penetrates a housing, such as in pumps and other rotating equipment, packing is used to create a seal around the shaft to prevent the escape of fluid. The packing gland allows for compression of the packing material against the shaft, which effectively limits leakage. By tightening the gland, the operator can control how much leakage occurs, achieving the desired balance between efficiency and maintenance needs. This adjustment capability is crucial for optimal equipment performance and longevity, as it helps manage the wear and tear on the packing material while maintaining sufficient lubrication and cooling of the shaft.
