Which statement regarding stationary mechanical seals is false?

The statement indicating that as the pump shaft turns, so does the sealing ring is not accurate. In stationary mechanical seals, typically found in pumps, the sealing ring is designed to remain stationary while the pump shaft rotates. This is a crucial characteristic of how these seals operate, as the sealing ring is held in place by the seal housing. The rotating part of the seal is usually the mating ring, which adheres to the rotating shaft, creating a sealing interface while preventing leakage.

Understanding the operation of both the sealing and mating rings is important in examining the performance and longevity of mechanical seals. By allowing one part to be stationary, the design effectively reduces wear and extends the life of the sealing components. Thus, the interaction between the rotating shaft and the associated components is vital for achieving effective sealing in mechanical applications.
