The installation method varies with the type of mechanical seal and the type of machine, but the installation essentials are almost the same. The installation steps and precautions are as follows:

(1) Determination of installation dimensions

During installation, the installation dimension of the mechanical seal shall be ensured according to the product instructions or samples.

(2) First, install the static ring and the gland on the shaft together, taking care not to collide with the shaft, and then install the moving ring assembly. The set screws of spring seat or drive seat shall be tightened evenly in several times.

Before the gland is fixed, manually push the compensation ring for axial compression. After loosening, the compensation ring can automatically spring back without clamping stagnation, and then lock the gland bolts evenly.

Before installation, the shaft (sleeve) and gland shall be free of burrs and the bearing shall be in good condition; Seals, shafts, seal chambers and glands shall be cleaned. In order to reduce the friction resistance, a thin layer of oil shall be applied to the part where the mechanical seal is installed on the shaft for lubrication. In consideration of the compatibility of the rubber O-ring, soapy water can be applied if oil is not suitable. Floating static ring without anti rotation pin should not be oiled and should be installed into the gland dry.
