Which of the following is a common pump problem?

Cavitation is a common pump problem that occurs when the pressure within a pump drops below the vapor pressure of the fluid, causing vapor bubbles to form. These bubbles can implode when they enter areas of higher pressure within the pump, leading to shock waves that can cause significant damage to the impeller and other components. This phenomenon typically results in a loss of efficiency, increased wear and tear, and potential failure of the pump if not addressed.

When understanding pump issues, it's crucial to recognize the conditions that lead to cavitation, such as inadequate suction head, high fluid temperature, or obstruction in the pump's inlet. Monitoring and maintaining proper operating conditions can help prevent cavitation, ensuring the longevity and reliability of the pump system.
