Which risk increases when a regenerative turbine pump experiences excessive suction recirculation?

💡 Explanation

When excessive suction recirculation happens, cavitation occurs near the impeller vanes because localized pressure drops cause the fluid to vaporize, and the collapsing bubbles damage the vane surfaces. Therefore, premature wear results, rather than issues related to the motor, housing, or energy usage, which are caused by distinct mechanisms.
