What is essential to monitor in a centrifugal pump to ensure proper operation?

Monitoring the integrity of the check valve is essential in the operation of a centrifugal pump for several reasons. The check valve serves as a one-way valve that prevents backflow of the fluid being pumped. If the check valve is compromised, it can lead to fluid returning to the pump, which can cause a loss of prime, affect the efficiency of the pump, and potentially lead to equipment failure.

By ensuring the check valve is functioning correctly, you can maintain a constant flow and pressure within the system, which is critical for the pump's performance. This directly impacts the overall system efficiency and prevents possible operational hazards, such as cavitation or damage to the pump components.

While monitoring pressure difference, fluid temperature, and oil levels has its importance in certain contexts, ensuring the integrity of the check valve is more directly related to preventing backflow and maintaining the operational integrity of the centrifugal pump itself.
