Labyrinth-spiral mechanical seal

　2017-01-13　　

Labyrinth-spiral mechanical seal can be used to seal the pump shaft containing hard particles and corrosive media. It has developed from a single-rotation viscous seal to a seal that has little relationship with the viscosity of the medium and has a parking mechanism. It has the advantages of simple structure, no contact with parts, low wear and long life. It can be further developed into a labyrinth-screw pump.　　236.html,
