What is an advantage of using a mechanical seal over packing in a centrifugal pump?

Using a mechanical seal in a centrifugal pump offers the advantage of generally being easier to install compared to packing. Mechanical seals are designed to be more straightforward in their assembly process. They often consist of fewer components and can be fitted more easily into the pump housing, which allows for quicker installation and reduces labor time.

In contrast, packing requires a more complex setup, as it involves wrapping material around the pump shaft and ensuring proper tightness to prevent leaks. This process can be time-consuming and may require additional adjustments over time to maintain a good seal.

Furthermore, mechanical seals are designed to provide a more reliable sealing solution, which can lead to less frequent maintenance when compared to packing, which may need regular tightening or replacement to function effectively. This contributes to overall efficiency in operations and maintenance scheduling for pumps.
