What are the most common causes of hydraulic pump failure?

Overheating, fluid contamination, and internal wear from cavitation are the most common causes of hydraulic pump failure, with UAE heat and dust conditions accelerating all three compared to milder climates. Contamination from fine desert sand entering through worn seals or inadequate filtration is particularly prevalent locally. Addressing these root causes through consistent maintenance prevents most pump failures before they require a major repair. Sparkline Group's technicians diagnose which of these root causes is behind a specific failure before recommending a repair approach.
