As a Pump Cavitation Manufacturer, share with you.
A pump that is cavitating makes a steady, high-pitched whining sound. Since the sound is steady and does not reflect changes in the movement of the machine, it is often confused with bearing wear in the pump. Often a pump is replaced unnecessarily because it is cavitating.
Cavitation is caused when the pump is trying to deliver more oil than it can draw into its suction line. This may be because the oil is too cold and the viscosity is high or because the drive motor has been mismatched and is turning the pump too fast, but most of the time cavitation is caused by some blockage in the pump suction.
