Stainless steel mechanical seal installation requirements

Pump with stainless steel seals are known as mechanical seal, it is a kind of precision and complex mechanical components. As a kind of seal, need to use for a long time, the inevitable will be damaged, need to replace and reinstall. In order to ensure the quality of installation, the following, there is a stainless steel seals factory installed under the small make up give you a brief introduction of some of the requirements.
