The barrier system must be adapted to the specific mechanical seal using the mechanical seal

Regardless of whether liquid or gas is used, the barrier system must be suitable for the specific sealing application, and once any obstacle occurs in the mechanical sealing surface, it should be able to recognize the alarm immediately so that appropriate measures can be taken in time.

environmental control

In many application platforms, where mechanical seals are installed, the reliable operation and control environment of the seals need to be considered, so the following points must be paid attention to:

1. The seal should be installed on the high-strength main shaft with very small deviation. While the industry standard specifies a maximum tolerance of 0.002 in for sealing surfaces, the requirements for the spindle can be even higher.


2. The seal should be installed in a large-diameter seal chamber, which can improve the reliability of the seal. Almost all liquid pump manufacturers can provide such products.

3. Control the internal pressure of the stuffing box to avoid reaching the flash point.

4. Keep the temperature inside the stuffing box within the working parameters of the sealing material.

5. Keep the liquid in the stuffing box clean.
