Which risk increases when an abrasive slurry pump lacks adequate Net Positive Suction Head?

💡 Explanation

Pump cavitation and impeller erosion increases because inadequate Net Positive Suction Head causes the fluid to vaporize at the impeller inlet forming vapor cavities. These cavities collapse violently when they move into higher pressure regions causing cavitation and erosion; therefore eroding the impeller, rather than causing motor failure or deformation which are unrelated effects.
