Jan 06, 2017

1. Be sure to check that the installed mechanical seal is suitable for your application. When the transmission medium temperature is too high, too low or contain impurities particles, flammable, explosive, toxic, must take the appropriate sealing, washing, cooling, filtration and other measures.

2. Inspect the relevant hazard symbols, check installation and connection dimensions, and check the accuracy of the axial and radial dimensional tolerances on the shaft and cavity. (Shaft or sleeve finish is not greater than 1.6 microns, shaft or sleeve tolerance h7, seal cavity end face of the pump shaft runout every 3cm aperture is not greater than 0.015mm. Shaft radial runout should be less than 0.1mm, axial channeling Should be less than 0.15mm, "O" ring through the end of the sleeve should be smooth over angle chamfer, shoulder chamfering 3 × 10 °, end cap chamfering: 2 ~ 2.5 × 20 °).

3. Mechanical seal assembly drawings should be carefully read (the standard series of products can refer to product samples), to ensure that the mechanical seal installation size and tolerance.
