Which issue can arise from over-lubrication in pumps?

Over-lubrication in pumps can lead to increased operating temperatures. When excessive lubricant is used, it can cause a buildup that traps heat within the pump system. Lubricants are designed to reduce friction and wear, but when there is too much of it, it can actually hinder the normal operation of the pump by creating resistance and increasing thermal load. This increased heat can lead to degradation of both the lubricant and the components being lubricated, ultimately affecting the efficiency and lifespan of the pump.

In contrast, improved energy efficiency, reduced wear and tear on seals, and enhanced performance are typically associated with the appropriate amount of lubrication. Therefore, understanding the balance in lubrication is crucial in pump maintenance to avoid the negative consequences of over-lubrication.
