Cavitation is a critical issue that can severely impact the performance and lifespan of hydraulic pumps, especially when dealing with high-viscosity fluids. Cavitation occurs when the pressure in the hydraulic circuit drops below the vapor pressure of the fluid, leading to the formation of vapor bubbles. These bubbles can collapse violently, causing damage to the pump components and reducing the system’s efficiency. In high-viscosity fluid circuits, the risk of cavitation can increase due to the challenges associated with fluid movement and pressure dynamics. Here are some effective strategies to prevent and solve hydraulic pump cavitation issues in these systems.

Firstly, ensure that the hydraulic pump is properly sized for the application. Selecting a pump that is too small for the viscosity and flow requirements can lead to inadequate flow rates and increased pressure drops, thus promoting cavitation. Consult with hydraulic pump manufacturers to select the right type and model that can accommodate the specific properties of the high-viscosity fluid being used.

Secondly, optimize the system design to reduce pressure drops. High-viscosity fluids often require larger pipe diameters to facilitate smoother flow. Minimize sharp bends, restrictions, and long runs in the pipeline to decrease the frictional losses that contribute to pressure drops. Additionally, using low-friction fittings and valves can significantly improve the hydraulic circuit’s overall efficiency.
Another critical factor is to maintain a sufficient net positive suction head (NPSH). NPSH is the measure of the pressure available at the pump suction to prevent cavitation. Ensure that the system’s NPSH available (NPSHa) exceeds the required NPSH (NPSHr) as specified by the pump manufacturer. One way to increase NPSHa is by providing a larger suction tank and maintaining it at an appropriate level to increase the static pressure at the pump inlet.
