  • Troubleshooting Tips for Hydraulic Pumps - Womack Machine

    Cavitation is the inability of a pump to draw in a full charge of oil. When a pump starts to cavitate its noise level increases, and it may become extremely hot around the shaft and front bearing. Other symptoms of pump cavitation are erratic movement of cylinders, difficulty in building up full pressure, and a milky appearance of the oil.
