What may occur if the pump capacity is exceeded?

• A. Increased efficiency
• B. Enhanced performance
• C. Cavitation
• D. Reduced fuel consumption

Answer: (C)

When the pump capacity is exceeded, cavitation may occur. This phenomenon happens when the pressure in the pump falls below the vapor pressure of the liquid, causing vapor bubbles to form. These bubbles can collapse violently, leading to potential damage to the pump components, such as erosion, pitting, and loss of performance. Understanding cavitation is crucial for pump operation because it can severely compromise the integrity of the system, resulting in decreased efficiency and potentially costly repairs. It is essential for operators to manage pump capacity carefully to avoid pushing the system beyond its designed limits, thereby ensuring both reliable performance and the longevity of the equipment.
