← ScienceWhich risk increases when a centrifugal pump operates far from its best efficiency point?
A)Increased impeller cavitation and turbulence✓
B)Stator winding insulation thermal runaway
C)Rotor-stator mechanical shaft misalignment
D)Lubricant oxidation due to bearing shear
💡 Explanation
Operating far from the best efficiency point leads to increased hydraulic losses which generate turbulence and cause the **formation of vapor bubbles (cavitation)** within the impeller. Therefore, erosion increases, rather than the described electrical or lubrication failures which occur from unrelated operational stressors.
