 (2) Install the mechanical seal pump or other similar rotating machinery in the work shall not exceed the amount of Axial series 0.03MM.

 (3) mechanical seal is installed, you must shaft (or sleeve) sealed chamber cover seal and mechanical seal itself clean to prevent any impurities into the sealed area.

 (4) mechanical seal gland (including the stationary ring) is not installed in the case of not turning to prevent the dynamic and static ring scratch each other.

 (5) For the installation of a pump mechanical seal, the chamber in the open end must be exposed sealant to prevent leaking of liquid from the gland.
