• 24 Nov, 2023

LRC series liquid ring compressor is a kind of compressor with high performance and high compression ratio developed by our company according to the advanced experience of foreign countries and the latest water conservancy model. It has the advantages of simple structure, high energy efficiency, safety and reliability.

And has the following characteristics:

1. single-stage impeller, performance up to 0.7Mpa (G)

2. rear bearing positioning, clearance can be adjusted

3. bearing chamber with thin oil lubrication, higher loading capacity

4.upper suction and side discharge, easy start

5. pump body with bolt connection, safe and reliable

LRC liquid ring compressor is mainly used in petrochemical industry, torch gas and pharmaceutical gas transport recovery, sewage treatment, chlor-alkali and other industries, with high pressure, compact structure, reliable use, easy to operate and high pressure area pumping speed. Because it is in the isothermal state in the process of compression, LRC liquid ring compressor can better avoid dangers in the compression of flammable, explosive gas.
