Question 365General Subjects - Assistant Engineer

The correct answer is A) seal failure usually requires the immediate removal of the pump from service. The reasoning behind this is that mechanical shaft seals are designed to provide a tight seal between the rotating shaft and the stationary pump housing. Unlike mechanical packing, which can often be tightened or adjusted to address minor leaks, a mechanical seal failure typically requires the immediate removal of the pump from service for seal replacement. This is because a mechanical seal failure can lead to significant leakage that cannot be easily remedied without replacing the seal. The other options are incorrect because: B) mechanical seals can be designed for high-pressure applications, C) mechanical seals do require periodic maintenance and adjustment, and D) mechanical seals can be designed for high-temperature applications as well.
