What is a common indicator that pump packing needs to be replaced?

Visible leakage is a common indicator that pump packing needs to be replaced. When the packing around the pump shaft deteriorates or wears out, it can no longer create a proper seal, leading to leaks. This leakage can be observed as fluid escaping from the packing area, often indicating that the packing material has lost its integrity and is no longer effective in preventing fluid from escaping. It is essential to address this issue promptly, as ongoing leaks can result in decreased efficiency and potential damage to the pump and surrounding equipment.

In contrast, reduced noise levels, increased efficiency, and enhanced suction are not typically associated with the condition of pump packing. These conditions might suggest that a pump is operating efficiently, but they do not directly relate to the physical state of the packing material or the presence of leaks. Thus, visible leakage serves as a clear and practical sign that the pump packing requires attention.
