Date:May 15, 2020

The centrifugal pump plunger is mainly caused by the failure of the mechanical seal.


① The leakage of the sealing surface of the dynamic and static rings is mainly due to: the flatness of the end, which does not meet the requirements, or the surface is scratched; there is particulate matter between the ends, which prevents the face from running mutually;


② The leakage of the seal ring of the compensation ring is mainly due to: the deformation of the gland, the uneven preload force; the incorrect installation; the quality of the seal ring does not meet the standards; the type of the seal ring is not correct.
