China 2BE Series Water Ring Vacuum Pump - Energy-Efficient Solution from Reliable Suppliers and Factory
Strict assembly process
Strict control of assembly process ensures that the impeller and disc of the 2BE water ring vacuum pump maintain a 0.2 mm gap, ensuring the maximum performance of the pumping speed and extreme vacuum level.
Long service life
The designed service life is 20 years. Different materials of 2BE water ring vacuum pumps can be selected based on the pumping medium, such as carbon steel, stainless steel 304, 316L, 904L, 2205, 2507, etc.
Equipped with explosion-proof motors
Equipped with explosion-proof motors, capable of extracting explosive gases, and working in various flammable and explosive environments.
5 times longer than ordinary materials in service life
The shaft sleeve, the most easily damaged part, is all made of stainless steel by our company, which is 5 times longer than ordinary materials in service life.
effectively reduces noise
Efficient top-mounted gas-water separation structure not only saves space but also effectively reduces noise and working current.
be used for recovering the pumped solvent
Can be made into air-cooled water ring vacuum pump units and closed-loop water ring vacuum pump units, allowing the working fluid to be recycled, reducing wastewater discharge, and using organic solvents as the working fluid, or it can be used for recovering the pumped solvent.

- The performance parameters listed in the table were obtained under the conditions of saturated air as the intake medium at 20℃, working fluid temperature at 15℃, and exhaust pressure at 1013 mbar.
- The performance tolerance is ±10%.
- The selected motor power can operate under most working conditions. If the exhaust port pressure is high (0.02 – 0.05 MPa), the motor power should be increased accordingly; if the shaft power of the 2BE1 vacuum pump is relatively low when it is operating normally, a motor power closer to the shaft power can be selected, which is more energy-efficient.
