What does an increase in pressure differential above the manufacturer’s rating typically indicate?

An increase in pressure differential above the manufacturer’s rating typically indicates potential clogging in the system. When the pressure differential exceeds the specified limits, it suggests that the flow pathway is facing resistance, which is often caused by blockages or restrictions within the pipes, fittings, or equipment. This increased resistance requires the pump to work harder to maintain the desired flow rate, resulting in a higher pressure differential.

Understanding this concept is crucial because it highlights the importance of regular maintenance and monitoring of fluid systems. Clogging can lead to further issues such as decreased efficiency, potential damage to the pump, and increased energy consumption. Therefore, recognizing signs of abnormal pressure differentials can help in taking proactive measures to diagnose and resolve potential blockages before they cause significant problems in the system.
