  Water Ring Vacuum Pump     



vacuum pump 2BEC oil free water Liquid Ring buy Vacuum Pump price


The water ring pump was originally used as a self-priming water pump, and then gradually used in many industrial sectors such as petroleum, chemical industry, machinery, mining, light industry, medicine and food. In many processes of industrial production, such as vacuum filtration, vacuum water diversion, vacuum feeding, vacuum evaporation, vacuum concentration, vacuum rehydration and vacuum degassing, water ring pumps are widely used. Due to the rapid development of vacuum application technology, water ring pumps have always been valued in terms of obtaining rough vacuum. Because the gas compression in the water ring pump is isothermal, it can pump flammable and explosive gases, and also dust and water-containing gases. Therefore, the application of water ring pumps is increasing.

The 2BEC type water ring vacuum pump and compressor are not only high efficiency and energy saving, but also very suitable for long-term, continuous operation.

Operating under rough vacuum, the working conditions of liquid ring pumps are often extremely harsh. The 2BEC water ring vacuum pump has been designed to fully consider that it must be able to pump all kinds of gases. It has been widely used in papermaking, coal mines, power plants, vacuum filtration, chemical, petrochemical, food processing and other industries.

2BEC type water ring vacuum pump can be used with a variety of driving devices, such as belt drive, gearbox, synchronous motor, frequency converter, etc. In addition, in order to save space, a series operation mode driven by one motor can also be adopted, and up to four pumps can be operated in series at the same time.

When equipped with a middle partition, the left and right parts of the 2BEC water ring vacuum pump can operate at different vacuum degrees. As long as the suction pressure difference between the two parts is less than 80kPa, a 2BEC water ring vacuum pump can be used as two independent vacuum pumps. This feature further improves the operating flexibility of the 2BEC water ring vacuum pump.

1. There are large inspection ports on both sides of the pump cover, which can be used to check gaps, corrosion conditions and fouling.


2. The 2BEC water ring vacuum pump is prepared with suction and exhaust flanges on the top and side at the same time, and they have the same caliber, so the on-site installation is more flexible and convenient.


3. The bearings are all imported original bearings, which ensure the precise positioning of the impeller of the 2BEC water ring vacuum pump and the high stability during operation.


4. The impeller is made of nodular cast iron or welded by steel or stainless steel plates, which fully guarantees the stability of the 2BEC vacuum pump impeller under various harsh working conditions and greatly improves the service life of the 2BEC water ring vacuum pump.


5. The pump body is all made of steel plate or stainless steel plate, which improves the service life of the 2BEC water ring vacuum pump.


6. The shaft sleeve of the 2BEC water ring vacuum pump is the most vulnerable part. The company uses all stainless steel to make it, and its life span is 5 times longer than that of ordinary materials.


7. The pulley (belt drive) adopts a standard high-precision tapered pulley, which is reliable in operation, long in belt life and easy to disassemble.


8. The unique top-mounted gas-water separator saves space and effectively reduces noise.


9. All castings are made of resin sand with good surface quality. The surface of the casting does not need to be greasy, so that the 2BEC water ring vacuum pump has the best heat dissipation effect.


10.The mechanical seals (optional parts) are all imported parts to fully ensure that the 2BEC water ring vacuum pump has no leakage during long-term operation.

 As shown in the figure:  a proper amount of water is installed in the pump body as the working fluid. When the impeller rotates clockwise in the direction indicated in the figure, the water is thrown around by the impeller. Due to the centrifugal force, the water forms a closed ring of approximately equal thickness determined by the shape of the pump cavity. The inner surface of the upper part of the water ring is just tangent to the hub of the impeller, and the inner surface of the lower part of the water ring just touches the top of the blade (in fact, the blade has a certain insertion depth in the water ring). At this time, a crescent-shaped space is formed between the impeller hub and the water ring, and this space is divided by the impeller into several small cavities with the same number of blades. If the upper part of the impeller is 0° as the starting point, the volume of the small cavity becomes larger when the impeller rotates 180° before, and it communicates with the suction port on the end face. At this time, the gas is sucked in. When the suction ends, the small cavity It is isolated from the suction port; when the impeller continues to rotate, the small cavity changes from large to small, so that the gas is compressed; when the small cavity communicates with the exhaust port, the gas is discharged out of the pump.

In summary, the water ring pump relies on the change of the pump cavity volume to achieve suction, compression and exhaust, so it is a variable volume vacuum pump.
