← TechnologyWhich outcome occurs when a positive displacement pump runs dry without fluid for an extended period?
A)Decreased flow-rate due to cavitation
B)Instantaneous pump seizure from thermal expansion
C)Overheating and accelerated wear of internal components✓
D)Corrosion initiated by ingress of atmospheric moisture
💡 Explanation
When a positive displacement pump runs dry, lubricant starvation occurs because the fluid also acts as lubricant, leading to metal-on-metal contact and increased friction that accelerates wear. Therefore, overheating results rather than seizure, cavitation, or corrosion which depend on different failure modes and fluid properties.
