What is a potential consequence of over-lubricating a pump bearing?

Over-lubricating a pump bearing can lead to overheating due to the excess lubricant creating excessive friction and heat. When there is too much grease or oil in the bearing, it can impede the necessary flow of lubricant and create a seal that traps heat. This trapped heat can elevate the temperature beyond the operational limits of the bearing materials, leading to degradation, potential failure, or reduced lifespan of the bearing.

In a well-lubricated bearing system, the goal is to ensure the proper amount of lubrication to provide sufficient protection while allowing for the necessary movement. An optimal quantity of lubrication reduces friction, dissipates heat, and facilitates smooth operation. Conversely, if the lubrication exceeds the required amount, it disrupts this balance, causing overheating as the excessive lubricant generates considerable friction.

Understanding the proper lubrication practices is crucial for maintaining the efficiency and longevity of pump systems in wastewater management.
