Product Name: Unbalanced back to back structure double mechanical seal
Double mechanical seal has axial double mechanical seal and radial double mechanical seal. The structure of axial double mechanical seal is more compact than radial double mechanical seal.Double mechanical seal is suitable for medium itself for lubricity is poor, abrasive particle and gas is toxic, flammable, explosive, volatile, etc.
The structure of axial double mechanical seal is face to face or back to back, when the axial double mechanical seal is running, it should introduce 0.05～0.15MPa sealing liquid which pressure is higher than medium to improve the lubrication and cooling conditions between end face. At the same time, to isolate the medium from outside, it is possible to reach zero leakage of medium.
