What is the result of excessive leakage in a pump sealing?

Excessive leakage in a pump sealing typically results in increased operational costs. When seals are not functioning properly and allow fluid to escape, the pump must work harder to maintain performance levels. This can lead to higher energy consumption as the system compensates for lost fluid, resulting in more frequent and costly maintenance. Additionally, leakage can lead to potential environmental and regulatory issues if the pumped fluid is hazardous. Managing leaks effectively is critical not only for maintaining efficiency but also for controlling overall operating expenses, making option B the most accurate choice.
