Cavitation Liquid Ring Vacuum Pumps - Vacuum Pump & .

Cavitation Liquid Ring Vacuum Pumps. If your Liquid Ring Vacuum Pump is making an abnormal sound comparable to gravel going through the pump, cavitation is likely occurring. Cavitation is the result of gas bubbles under vacuum being subjected to an increase in pressure on the discharge port of the pump and imploding or collapsing.
