WORKING THEORY
Series SK, 2SK Water Ring Vacuum Pumps can be used to exhaust ordinary gases as well as condensable gases(such as water vapor). Because they have the features of isothermal compression, they can exhaust flammable and explosive gases. When the pump made up of anti-corrosion material is selected, it can be used for exhausting corrosive gases too.
2SK series two-stage liquid ring vacuum pumps can work well like two sets of SK series water ring vacuum pump.
Due to SK series vacuum pumps only reach the maximum vacuum of-700mmHg, to meet the high vacuum and the large pumping speed under high vacuum, China developed the 2SK series water ring vacuum pump in 80s in the 20th century.
ADVANTAGES
1. Simple structure and easy maintenance.
2. The mostly working medium is water and low maintenance costs.
3. Widely use in many areas and suction water vapor, flammable, explosive and various gases contain a small amount of dust and liquid.
4. The pump can works in the harsh condition

DESCRIPTION
2BVA Series Water Ring Vacuum Pump
WORKING THEORY
2BVA series vacuum pump suitable for pumping gas and water vapor, inspiratory pressure can reach 33 mbar definitely pressure (vacuum degree 97%).
When the vacuum pump long-term work under the condition of pressure lower than 80 mbar, gas corrosion protection tube shall be connected to the pump to protect the pump.
Equiped with air injector, inspiratory pressure can reach 10 mbar. Injector can be directly installed on the vacuum pump.
When used as compressor, the biggest pressure can be 0.26 mbar (pabs).

APPLICATIONS
Water ring vacuum pumps and compressors are widely used in petrochemical, pharmaceutical, food, sugar industry, and other fields, because during the working process, the compression process of gas is isothermal, so it is not easy to produce risk when pumping flammable and explosive gas compression, thus its application more widely.
Products Name: 2BEA WATER RING VACUUM PUMP
WORKING THEORY
2 BEA series water ring vacuum pumps and compressors, is high efficiency and energy saving products which based on years of scientific research and production experience, combining the international advanced technology, research and development. It is typically used for suction the gas which is not containing solid particles, insoluble in water and no corrosive, so as to form a vacuum and pressure in an airtight container.
By changing the structure of the material, can also be used for pumping corrosive gases or use corrosive liquid fluid as working fluid.
ADVANTAGES
This series pump adopt the structure of single stage single function, has the advantages of simple structure, convenient maintenance, reliable operation, the advantages of high efficiency and energy saving, and can adapt to large displacement, such as condition of shock wave load.
