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.
