If a pump operates above its maximum rated capacity, what is likely to occur?

When a pump operates above its maximum rated capacity, it is subjected to conditions that it was not designed to handle. This can lead to several adverse outcomes, one of which is mechanical failure or damage to the pump components. Exceeding the maximum capacity causes excessive stress on the pump's parts, including the impeller, bearings, and seals. This stress can lead to overheating, cavitation, and ultimately permanent damage, resulting in the need for repairs or replacement.

In contrast, running a pump at a capacity below its specifications generally increases efficiency and improves performance. Operating within safe limits ensures longevity and reliability, while consistently exceeding those limits puts the pump at risk.
