What is typically the most common cause of pump failure?

Improper lubrication is typically the most common cause of pump failure because it directly impacts the pump’s mechanical components. Pumps rely on sufficient lubrication to facilitate smooth operation by reducing friction between moving parts. When lubrication is inadequate, it can lead to excessive wear and tear on bearings, seals, and other critical components, causing them to fail prematurely. This failure may result in increased operational temperatures and ultimately catastrophic breakdowns.

In many cases, operators may have a regular maintenance schedule that includes checking lubrication levels and the condition of lubricants. However, if these checks are overlooked, or if the wrong type of lubricant is used, it can significantly increase the risk of pump failure.

While electrical issues, pump cavitation, and corrosion can also lead to pump failure, they do not occur as frequently as issues associated with improper lubrication. Electrical failures, for instance, might result from faulty wiring or overloads, while cavitation generally occurs under specific operational conditions related to flow and pressure. Corrosion is often a result of chemical reactions over a longer period but doesn’t tend to be the immediate cause of numerous pump failures.
