一、Features: 
1. The flow-through parts of medium and low pressure liquid ring compressor are firmly and reliably designed.
2. Adopt mechanical seal as standard configuration, meet higher environmental protection requirements, seal reliably and reduce equipment maintenance. It is also possible to choose a more secure integrated double face seal according to the user's working condition. Equipped with machine seal auxiliary flushing device, can compress the poisonous gas, and guarantee the safety and reliability.
3. Stainless steel impeller, as a conventional material, improves the corrosion resistance of the pump. When made of alloy steel, more stringent conditions can be applied.
4. High single-stage compression ratio, significant energy saving effect, and lower equipment operation cost.
5. The work process is close to an isothermal contraction, especially suitable for dealing with flammable and explosive gas.
