Product introduction
2BE3 series water ring vacuum pumps and compressors are high-efficiency and energy-saving products developed by our company combined with the advanced technology of international congeneric products. They are usually used to suck gas that does not contain solid particles, is insoluble in water, and is non-corrosive, so as to form a vacuum in a closed container and pressure. By changing the structural materials and adding anti-corrosion coatings, it can also be used to suck corrosive gases or use corrosive liquids as working fluids. It is very suitable for long-term, continuous operation. 2BE3 series products have been designed with full consideration that it must be able to extract a variety of gases.
2BE3 can be used with various drive devices, such as belt drive, gearbox, synchronous motor, variable frequency governor, etc. In addition, in order to save space, a series operation mode driven by one motor can also be adopted. It has been widely used in papermaking, coal mine, power plant, vacuum filtration, chemical industry, petrochemical industry, food processing and other industries.
Features
● This series of pumps adopts a single-stage and single-acting structure, which has the advantages of simple structure, convenient maintenance, reliable operation, high efficiency and energy saving, and can adapt to harsh working conditions such as large displacement and load shock waves.
● Unique and flexible suction and exhaust port optimization design, allowing upper and side exhaust methods, easy to install on site. In limited installation space, 2BE3 can be installed with an upper separator, reducing the floor space and eliminating the need for trenches.
● The impeller is welded and treated with high temperature solidification and melting, and the blade is punched, formed and shaped at one time. The impeller and the pump shaft adopt hot-installed interference fit, which has reliable performance and stable operation. Can adapt to the harsh working conditions of load shock waves.
● Through the optimized design of the disc and impeller, the internal fluid backflow efficiency is improved, and the energy saving reaches 6 to 8%. The effect is obvious.
● The supply range of pumps can be flexibly selected according to customer requirements:
Pump head: including top-mounted separator and connecting pipe.

Note: 1. The power of the motor selected above can work under most working conditions. If the exhaust port pressure is high (gauge pressure 0.02~ 0.05MPa), the motor power should be increased accordingly; if the working pressure of the actual 2BE3 vacuum pump corresponds to a smaller shaft power (refer to the shaft power curve), the motor power close to the shaft power can also be selected, which can save more energy.
2. The above vacuum pump speed is the reference speed, and the actual speed is determined according to the transmission mode and customer requirements.
3. 2BE3 400/420 belt drive can choose the speed: 327/349/393/446/475/498/527rpm.
4. Belt drive is not recommended for vacuum pumps above 2BE3 500.
5, gear reducer drive installation size to determine the speed, gear reducer manufacturer to determine.
