Suction lift limitation cavitation

Suction lift limitation refers to the maximum height a pump can draw fluid from a source due to atmospheric pressure and the vapor pressure of the liquid. Cavitation occurs when the pressure in the pump drops below the vapor pressure, leading to the formation of vapor bubbles that can collapse violently, causing damage to the pump components. This phenomenon limits the effective suction lift, as excessive lift can induce cavitation, reducing pump efficiency and lifespan. To mitigate cavitation, it's essential to maintain appropriate operating conditions, including keeping the pump inlet pressure above the vapor pressure of the fluid.
