Cavitation describes the phase change from liquid to gas (boiling) that occurs in a device when the inlet pressure is too low for a given fluid at a given temperature. Since the vapor bubbles take up more volume than the liquid, a reduction of fluid flow occurs. As these vapor bubbles move from the inlet area of a pump toward an area of higher pressure, the bubbles collapse back to a liquid phase, and at the moment of collapse (implode), a powerful shock wave develops within the liquid. This shock wave can blast particles off of nearby solid surfaces, creating pits or caves. Over time this pitting can cause a catastrophic failure. Why is suction pressure important?
