Hydraulic systems are essential components in construction equipment, providing the necessary power for a variety of tasks. However, one of the most common issues that can affect the performance of these systems is pressure loss in the hydraulic pump. If you are experiencing low pressure in a hydraulic system, it is crucial to identify the source of the problem to ensure efficient operation. This article outlines the steps to troubleshoot hydraulic pump pressure loss in fluid systems for construction equipment.

First, it is important to understand that several factors can contribute to pressure loss in hydraulic systems. These may include fluid leaks, pump wear, filter blockages, or issues with the hydraulic circuit itself.

Start your troubleshooting process by conducting a visual inspection of the entire hydraulic system. Look for any signs of fluid leaks around hoses, fittings, and connections. Leaks can significantly affect the pressure levels in the system and must be addressed immediately. Even a small leak can lead to substantial pressure loss during operation.
Next, check the hydraulic fluid level and quality. Low fluid levels or contaminated hydraulic fluid can cause performance issues, including pressure loss. Ensure that the fluid is at the proper level and clean. If the fluid appears dirty, cloudy, or has particulate matter, it may need to be replaced or topped up with fresh fluid.
Once you have ensured that there are no external leaks and that the fluid is at an appropriate level, examine the hydraulic pump itself. Look for signs of wear or damage to the pump components. If the pump is worn out or damaged, it may not generate sufficient pressure. Pay attention to the pump’s seal and mounting brackets, as well as the condition of the drive motor.
