The word cavitation comes from the Latin word “cavus” meaning hole or cavity. Cavitation refers to conditions within the pump, when the local pressure drops below the vapor pressure of the liquid, and cavities filled with water vapor form. The cavities collapse as soon as the vapor bubbles reach regions of higher pressure.Cavitation is one of the most important causes that affect performance, operability, reliability and pump life.A general local pressure drop may be produced by one of the following:
An increase in the static lift of the centrifugal pump.
A decrease in the atmospheric pressure with a rise in the altitude.
