What happens when a hydraulic pump is low on oil?

When a hydraulic pump is low on oil, it can lead to inadequate lubrication and cooling, resulting in increased friction and wear on internal components. This can cause the pump to operate inefficiently, potentially leading to overheating and mechanical failure. Additionally, low oil levels may result in cavitation, where vapor bubbles form and collapse, further damaging the pump and reducing its performance. Regular monitoring and maintenance of oil levels are essential to ensure proper hydraulic system operation.
