Product Description

2BV series liquid ring vacuum pump is suitable for suction gas and vapour ,and the suction pressure can reach 33mbar (abs.)(i.e.97% vacuum degree ).When the liquid ring vacuum pump works under the condition that the suction pressure is near the limited vacuum (saturated pressure of the operating liquid )for a long time ,it should couple with the cavitation protection pipe in order to protect the pump .When it's used as a compressor ,the maximum pressure is 0.26mpa(abs).As a new generation of energy-saving product ,2BV series liquid ring vacuum pump will replace the SK and 2SK series liquid ring vacuum pumps and W,WY,WL series reciprocating vacuum pumps completely with their superior performance and advantages .

2BV6 series liquid ring vacuum pumps and compressors are mainly used for pumping the explosive gas or working in the flammable and explosive environment .The technical parameter of each type is the same as the corresponding type of the 2BV2and 2BV5 series products .

Advantages:

1,The direct-coupled design is easy installation and can save space.
2,The pump has the cavitation protection port opens (or connects with the separator )in the case of ensure maximum suction effect to eliminate the noise of cavitation and protect the pump
3,2BV whole series are all use the aluminum bronze impeller with high strength and raise its corrosion resistance and durability .If the liquid flows parts adopt stainless steel ,the pump can work in the more hard condition .

The main applications of the 2BV series water ring vacuum pumps are as follows:
 
- In the petrochemical industry: During the negative pressure distillation process, it is used to extract the non-condensable gases at the top of the distillation column, maintaining the vacuum degree inside the distillation column to ensure the smooth progress of the distillation process. In the vacuum filtration process, it provides a vacuum environment for the filtration equipment, accelerating the speed of solid-liquid separation and improving production efficiency. In the MVR evaporation system, it is responsible for removing non-condensable gases, creating a vacuum environment, reducing the boiling point of the liquid, and achieving efficient evaporation and concentration.
 
- In the pharmaceutical industry: During the vacuum drying process of pharmaceuticals, it removes the air and water vapor inside the drying oven, enabling the pharmaceuticals to dry quickly at a low temperature and preventing the active ingredients of the pharmaceuticals from decomposing or deteriorating due to high temperature. In the vacuum distillation process, it is used for operations such as concentrating medicinal liquids and extracting active ingredients. By creating a vacuum environment, it reduces the boiling point of the liquid to achieve the separation of different components.
 
- In the food and beverage industry: In the production of fruit juices, it is used for the vacuum degassing of fruit juices, removing gases such as oxygen in the fruit juices to prevent the fruit juices from oxidizing, changing color, and deteriorating, and extending the shelf life. In the processing of vacuum fried foods, it provides a vacuum environment for the frying equipment, enabling the foods to dehydrate at a low temperature and maintaining the color, taste, and nutritional components of the foods.
 
- In the electronics industry: In the vacuum coating process of electronic components, it provides a stable vacuum environment to ensure that the coating materials are evenly deposited on the surface of the components, improving the quality and adhesion of the coating. In the semiconductor manufacturing process, it is used for vacuum adsorption in the processes of wafer cutting and packaging, fixing the wafers and chips to ensure the processing accuracy.
 
- In scientific research laboratories: It provides a vacuum environment for vacuum drying ovens, vacuum distillation devices, vacuum coating equipment, etc. in the laboratory to meet the experimental requirements. In materials science experiments, it is used for the preparation of nanomaterials, thin film materials, etc. By removing the gases inside the reaction vessel, it creates a pure reaction environment.
 
- In other fields: In the aeration process of sewage treatment, it provides negative pressure for the aeration tank, enabling the air to mix better with the sewage and promoting the decomposition of pollutants by microorganisms. In the paper industry, it is used for the vacuum dehydration of paper and the vacuum suction transfer of paper machines, improving the drying efficiency and quality of paper. In engraving machines, it is used for quickly adsorbing materials, keeping the materials stable during the processing, and improving the processing accuracy and efficiency.
