Built-in mechanical seal and external mechanical seal
- May 29, 2018 -

    Built-in mechanical seal: The mechanical seal is installed in the sealed chamber.

    Outer-mounted mechanical seal: The mechanical seal is installed outside the sealed chamber.

    Because the built-in mechanical seal has a good stress, the specific pressure increases with the increase of the pressure of the medium, and the leakage direction of the built-in mechanical seal is opposite to that of the centrifugal force. Therefore, the built-in mechanical seal is generally selected. Only when the corrosive medium is extremely strong, and do not want to consider using a pressure double mechanical seal, only consider the use of external mechanical seals.
