What is the most common cause of hydraulic pump failure?

The most common cause of hydraulic pump failure is often due to contaminated fluid. Contaminated fluid can introduce particulates, water, or other impurities into the hydraulic system, which can cause significant damage to the internal components of the pump and other hydraulic circuit elements. Over time, contaminants can wear down precision surfaces, lead to increased friction, and contribute to overall system inefficiencies. This can result in pump failure, reduced performance, overheating, and ultimately cause the hydraulic system to malfunction.

The importance of maintaining clean hydraulic fluid cannot be overstated, as it directly impacts the longevity and reliability of hydraulic pumps. Regular filtration, monitoring of fluid quality, and adhering to maintenance schedules can help mitigate the risks posed by contaminated fluid in a hydraulic system.
