2BE Series Water Ring Vacuum Pump - Energy-Efficient Solution from China Suppliers and Factory
Extremely high vacuum level
Through the integration of imported technology, the 2BE1 has an extreme vacuum level of -0.098 MPa
Fast pumping speed
The 2BE water ring vacuum pump has a single-stage structure, low energy consumption, and a large pumping capacity. The pumping speed range is 5 - 635 m3/min.
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.
Equipped with explosion-proof motors
Equipped with explosion-proof motors, capable of extracting explosive gases, and working in various flammable and explosive environments.
effectively reduces noise
Efficient top-mounted gas-water separation structure not only saves space but also effectively reduces noise and working current.

The 2BE1 series vacuum pumps achieve a limit vacuum level of -0.098 MPa (3300 Pa) across all listed model configurations.
Depending on the specific model and speed requirements, 2BE1 series units support either Direct Connection or V-belt transmission methods.
Parameters were verified with saturated air at 20°C as intake medium, working fluid temperature at 15°C, exhaust pressure at 1013 mbar, with a performance tolerance of ±10%.
If the exhaust port pressure operates between 0.02 - 0.05 MPa, motor power should be increased accordingly to handle the added load safely.
When normal shaft power is comparatively low during stable operation, selecting a motor capacity closely matched to the shaft power ensures optimal energy conservation.
The largest model listed (2BE1 403 with 200 kW motor) delivers a maximum exhaust volume of up to 123 m³/min with DN300 pipe connections.
