It is composed of two sets of single-end dry gas seals. The principle of "gas blocking" is used instead of "liquid blocking", and the medium is sealed with a sealing gas with a pressure higher than the sealing cavity pressure of 0.2 ~ 0.3Mpa to ensure that the process medium achieves zero environment Escape, meet VOC emission requirements, safety and environmental protection.
A small amount of sealing gas has entered the process. The seal has high requirements on the pressure of the sealed air source. It must be higher than the pump cavity pressure at any time without interruption.
The seal adopts cartridge type, convenient installation and disassembly, non-contact operation, energy saving, safety and environmental protection, reliable performance, simple operation, and an average service life of up to 3 years.
Pressure: 0 ~ 4MPa
Temperature: -104 ~ 260 ℃
Speed: ≤3600r / min
Applicable working conditions:
Suitable for various fluid media, mainly used for toxic and harmful, high temperature, easy coking, easy self-aggregation, strong corrosion, granular media, etc. Such as H2S fluid media, solvents, benzene, quench oil, tar, methanol, etc.
