Here are four situations when it isn’t appropriate to use a stuffing box that you will want to know.
1. If the fluid being pumped is highly abrasive or corrosive. The packing material in the stuffing box may wear out quickly, which could mean frequent replacement and maintenance. In this case, it would be better to use a different type of seal, such as a mechanical seal in a centrifugal pump.
2. If the pump operates at very high pressures or temperatures, the packing material in the stuffing box may not withstand extreme conditions. Using a different packing material or a different sealing system may be necessary.
3. If the pump operates in a high-vibration environment, the stuffing box may not be able to maintain its tight seal. This can lead to fluid leakage due to the vibrations.
