Cartridge type double-end mechanical seal structure;
The sealing liquid pressure is at least 0.14MPa higher than the medium pressure;
A downstream pumping spiral groove is formed on the end face of the medium side seal, and the sealing liquid is conveyed to the downstream process medium during work. Avoid leakage of process media;
Atmospheric side can adopt a combination of downstream pumping and upstream pumping to avoid leakage of sealing fluid;
Liquid film lubrication, low power consumption;
Adapted to granular media.
Pressure: 0 ~ 4.0MPaG
Temperature: -40 ~ 200 ℃
