2BV series liquid ring vacuum pump is suitable for gas and water vapor extraction. The suction pressure can reach 33 mbar absolute pressure (97% vacuum degree). When the suction pressure of liquid ring vacuum pump is close to the limit vacuum (saturated vapor pressure of working fluid), the cavitation protection pipe should be connected to protect the pump. When used as a compressor, the maximum pressure is 0.26 MPa (absolute pressure).

2BE3 series liquid ring vacuum pumps and compressors, this product is not only efficient and energy-saving, but also very suitable for long-term, continuous operation. The working conditions of liquid ring pumps are often very harsh when they operate in rough vacuum. 2BE3 series products have been fully considered in the design that it must be able to extract a variety of gases. It has been widely used in papermaking, coal mine, power plant, vacuum filtration, chemical industry, petrochemical, food processing and other industries.
