Important Notes
- 1. 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.
- 2. The performance tolerance is ±10%.
- 3. 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 operating normally, a motor power closer to the shaft power can be selected, which is more energy-efficient.

Frequently Asked Questions
Q
What is the limit vacuum level for the 2BE1 series liquid ring vacuum pumps?
All models in the 2BE1 series achieve a limit vacuum level of -0.098 MPa (3300 Pa), making them highly effective for industrial vacuum applications requiring deep and stable vacuum conditions.
Q
Under what conditions were the performance parameters in the table measured?
The performance data was measured with saturated air as the intake medium at 20℃, a working fluid temperature of 15℃, and an exhaust pressure of 1013 mbar. A performance tolerance of ±10% applies to all listed values.
Q
What transmission methods are available for the 2BE1 vacuum pump series?
The 2BE1 series supports two transmission methods: direct connection and V-belt drive. Smaller models such as 2BE1 103 and 2BE1 153 use direct connection, while larger models offer both options depending on the required pump speed and power configuration.
Q
How should I select the correct motor power for my application?
The listed motor powers cover most standard working conditions. If the exhaust port pressure is elevated (between 0.02 and 0.05 MPa), you should increase the motor power accordingly. Conversely, if the actual shaft power during normal operation is lower than expected, selecting a motor closer to the shaft power will improve energy efficiency.
Q
Which 2BE1 model offers the highest maximum exhaust volume?
The 2BE1 403 model offers the highest maximum exhaust volume of up to 123 m³/min at 200 KW power with a pump speed of 472 r.p.m, using a V-belt transmission and DN300 pipe diameter. It is best suited for large-scale industrial vacuum requirements.
Q
What pipe diameter is required for the 2BE1 403 model?
The 2BE1 403 model requires an intake and exhaust pipe diameter of DN300. Ensuring the correct pipe diameter is critical for maintaining optimal flow rates and achieving the specified vacuum performance.
