The 2BEC series water ring vacuum pump and compressor, combined with advanced technology from similar international products, is a highly efficient and energy-saving product that has been re researched and developed. It is usually used to extract gases that do not contain solid particles, are insoluble in water, and are non-corrosive, in order to form vacuum and pressure in sealed containers. By changing the structural materials, it can also be used to extract corrosive gases or use corrosive liquids as working fluids. Widely used in industries such as paper, chemical, petrochemical, light industry, pharmaceuticals, food, metallurgy, building materials, electrical appliances, coal washing, mineral processing, fertilizers, etc.
