Liquid Ring Vacuum Pump

The Liquid Ring Vacuum Pump relies on the change of the pump chamber volume to achieve suction, compression and exhaust. Therefore, the Liquid Ring Vacuum Pump is a variable volume vacuum pump. The pump body is equipped with an appropriate amount of water as the working fluid. When the impeller rotates, the upper inner surface 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 equal to the number of blades. If the lower part of the impeller is 0° as the starting point, the volume of the small cavity becomes larger when the impeller rotates 180° before the rotation, and it is connected to the suction port on the end face, and 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 Liquid Ring Vacuum Pump.

A liquid ring vacuum pump is a rotating positive-displacement pump. It is commonly used for processes like liquid priming, distillation, evaporation, central vacuum system, extrusion, bottle filling, packaging, vacuum forming, cooking, holding & so on.

Liquid ring vacuum pumps utilize water or other processes compatible liquid as the sealant in the process of generating vacuum pressure. It is a vacuum pump, simple to operate, with no contacting parts, making it a safe and reliable choice for handling dirty and potentially dangerous gas streams. It is available in single and two-stage designs and also configured as compressors for even more versatility.

With robust construction and only one moving part, the rotor (which is mounted on a shaft supported by a set of bearings), liquid ring vacuum pump is designed for long service life. It is a cost-effective pump with less wear and simpler, affordable maintenance.

The 2BE1 series Liquid Ring Vacuum Pump is an energy-efficient product developed by our company in combination withthe advanced technology of imported products. This series of vacuum pumps is a single-machine single-acting structure withthe advantages of simple structure, convenient maintenance, reliable operation, high efficiency and energy saving . it is usuallyused to pump air or other gases that are insoluble in water, do not contain solid particles, and are non-corrosive, so as toform a certain vacum degree in a closed container.Equipped with an explosion-proof motor , it can pump flammable andexplosive gases. The pump body material is corrosion-resistant material or after corrosion-resistant reatment, it can pumpgases with certain corrosiveness.

The 2BE1 series Liquid Ring Vacuum Pump is widely used in petrochemical, light industry,chemical industry, pharmaceutical, paper making, metallurgy, building materials, electrical appliances, food, coal washing,mineral processing, fertilizer and other industries.

Products Description

Products Construction

Vacuum-Pump

CAUTION : DO NOT RUN THE PUMP WITHOUT SERVICE LIQUID AND SHAFT SEAL FLUID.

1) The normal service liquid level should be no higher than the shaft centerline. The pump may be started with a low service liquid level as long as a supply is available immediately after start-up.
2) Open any valves in the suction and discharge lines.
3) Confirm the pump rotation with the arrow on the casing by jogging the motor.
4) Start the motor, ensure service liquid supply, and set regulating valve, when used, for optimum

Products Main advantages

1,lmpeller material is all cast by ductile iron or welded by steel plate, which fully guarantees the stability of the impeller undervarious harsh working conditions and greatly improves the service life of the 2BE1 vacuum system.
2,Pump body is made of steel plate, which improves the service life of the 2BEL vacuum system.
3,Sleeve is made of high-chromium stainless steel, which increases the service life of ordinary materials by 5 times. Thepulley (obelt drive) adopts a standard high-precision cone sleeve puly, which is reliable in operation, easy to disassemble,and has a long service life.
4,Coupling (direct drive) adopts a standard high-strength elastic coupling, and the elastic element is made of polyurethanematerial, which is stable and reliable in operation and has a long service life.
5,Bearing adopts imported bearings to ensure the precise positioning of the impeller of the 2BE1 vacuum system and highstability during operation.
6,Mechanical seal (optional accessories) adopts imported parts to fully ensure that the 2BE1 series vacuum pump has noleakage during long-term operation.
7, Inner wall line of the pump body adopts a line similar to an elliptical mesh to ensure the best air extraction effect.
8,Unique top-mounted gas-water separator saves space and effectively reduces noise.
