Different equipment requires different seals, but the installation process is quite different.

The type performance and sealing requirements of the seals vary from one component to another. The installation process we explain here is applicable to all seal installations. I hope to help you here.


1. Before loading, the shaft (sleeve sleeve) and gland should be free of burrs and the bearing condition is good; the seal, shaft, seal chamber and gland should be cleaned. In order to reduce the frictional resistance, the mechanical seal on the shaft should be thinly coated with a layer of oil for lubrication. Considering the compatibility of the rubber O-ring, if it is not suitable, apply soapy water. The floating static ring does not have an anti-rotation pin structure. It should not be oiled. The gland should be installed dry.
2. Determination of installation size

When installing, the installation dimensions of the mechanical seal should be guaranteed according to the product's instruction manual or sample.

3. First install the static ring and the gland on the shaft, taking care not to touch the shaft, and then load the moving ring assembly. The set screws of the spring seat or the drive base should be tightened evenly several times. Before the gland is fixed, the compensating ring is manually pressed for axial compression. After the loosening, the compensating ring can automatically spring back without jamming, and then the gland bolt is evenly locked.
