Which outcome occurs when a positive displacement pump rapidly cycles at very low flow rates?

A)Increased fluid viscosity due to shear

B)Accelerated wear of the pump components✓

C)Reduced pump efficiency due to backflow

D)Elevated fluid temperature from cavitation

💡 Explanation

When a positive displacement pump cycles rapidly at low flow, increased starts and stops accelerate mechanical fatigue because the components experience repeated stress cycles. Therefore accelerated wear occurs, rather than viscosity increase, efficiency drop, or high cavitation, which require different operational issues.
