2BE series water ring vacuum pumpDetailed product description：

Scope of Application
The 2BE series water ring vacuum pump and compressor are highly efficient and energy-saving products developed for pumping gases that do not contain solid particles, are insoluble in water, and are non corrosive, in order to create a vacuum and pressure in a closed container. By changing the structural material, it can also be used to extract corrosive gases or use corrosive liquid as the working fluid. Widely used in industries such as papermaking, chemical, petrochemical, light industry, pharmaceuticals, food, metallurgy, building materials, electrical appliances, coal washing, mineral processing, fertilizers, etc.

This series of pumps adopts a single-stage action structure, which has the advantages of simple structure, easy maintenance, reliable operation, high efficiency and energy saving, and can adapt to harsh working conditions such as large displacement and load impact fluctuations.
