There are a wide variety of mechanical seals for pump, but there are five main leakage points.

(L) the seal between the shaft sleeve and the shaft (this is a static seal, mainly using a tetrafluoroethylene gasket).

(2) seal of moving ring or static ring and shaft sleeve (this is static seal, mainly using O type ring or bellows).

(3) the seal between the dynamic and static rings (this is the dynamic seal, which is the most easy to leak in the seal, and the wear of the friction pair will lead to leakage after the long running time).

(4) the seal between the static ring and the static ring seat (this is the static seal, mainly using the O type ring);

(5) the seal between the sealing end cover and the pump body (this is a static seal, mainly using a tetrafluoroethylene).

Generally speaking, the leakage between the shaft and the seal end cover and the pump body is easy to be found and solved, but it needs to be carefully observed. The rest of the leak is intuitively Nanbian and don't judge, should be based on long-term management, maintenance practice, observation, analysis and Research on the leakage symptoms, to draw the right conclusions.
