technical data:
2BV series vacuum pump is an upgraded product developed with new technology on the basis of traditional water ring vacuum pump in China. It adopts the design of pump coaxial direct connection, high reliability, easy installation and maintenance, and its volume is 30% less than that of traditional vacuum pump. It runs balanced, noise is less than 62 dB, has self-priming ability, and is easy to operate. Because of the oil-free design, it is basically free from maintenance because of the use of mechanical seals to eliminate leakage. 50% of the working fluid of the gas water separator equipped with the pump can be recycled, which reduces pollution and operation cost. Bronze impeller is used in the pump to improve its corrosion resistance. According to the user's requirements, the stainless steel material is used, so the pump can operate normally in harsh environment. Therefore, it is widely used in chemical industry, medicine, food, papermaking and steel industry.
Performance characteristics
1. Pump coaxial direct connection design saves space and is easy to install.
2. The mechanical seal is used as the standard configuration, which eliminates the leakage and is easy to maintain.
3. The operation is stable and the noise can be as low as 62 dB.
4. Uniform corrosion resistant design, bronze impeller improves pump corrosion resistance, stainless steel material is more suitable for more demanding applications.
5. The unique flexible exhaust port design will not produce over compression, which ensures the best efficiency of 2BV within its performance range.

Working principle of water ring vacuum pump / liquid ring vacuum pump
The water-ring vacuum pump is a kind of coarse vacuum pump. The limit vacuum it can obtain is 2000-4000 Pa. The series air ejector can reach 270-670 Pa. Water ring pump can also be used as compressor, called water ring compressor, is a low-pressure compressor, its pressure range is 1-2X105 Pa meter pressure.
Water-ring vacuum pumps were originally used as self-suction pumps, and then gradually used in petroleum, chemical, mechanical, mining, light industry, medicine and food and many other industrial sectors. In many industrial processes, such as vacuum filtration, vacuum water diversion, vacuum feeding, vacuum evaporation, vacuum concentration, vacuum moisture regain and vacuum degassing, water ring pump has been widely used. Due to the rapid development of vacuum application technology, water ring pump has been paid much attention in obtaining coarse vacuum. Because the gas compression in the water ring pump is isothermal, it can extract flammable and explosive gases, in addition, it can also extract dust, water-bearing gases, so the application of water ring pump is increasing.
The pump body contains proper amount of water as working fluid. When the impeller rotates clockwise in the diagram, the water is thrown around by the impeller. Due to the centrifugal force, the water forms a closed ring which is approximately equal to the thickness of the pump cavity. The inner surface of the lower part of the water ring is exactly tangent to the hub of the impeller, and the upper inner surface of the water ring is just at the tip of the blade (in fact, the blade has a certain insertion depth in the water ring). At this time, a crescent space is formed between the hub and the water ring of the impeller, which is divided into several small cavities equal to the number of blades. If the lower zero of the impeller is taken as the starting point, the area of the small cavity increases from small to large when the impeller rotates 180 degrees, and is connected with the suction port on the end face. At this time, the gas is sucked in, and the small cavity is isolated from the suction port when the suction is finished. When the mouth is connected, the gas is discharged out of the pump.
