Pump school: what are the solutions to pump cavitation?

When the pressure of flowing liquids drops to, or below, the liquid’s vapour pressure, the liquid boils and vapour cavities (bubbles) form locally inside the liquid. If the pressure within the flow path subsequently increases above the vapour pressure, the vapour cavities implode, releasing energy. The formation and sudden collapse of these bubbles is called cavitation.
