Important Notes
- 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.

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 suitable for demanding industrial vacuum applications.
Q
Under what conditions are the performance parameters in the table measured?
The parameters were measured using saturated air as the intake medium at 20℃, with a working fluid temperature of 15℃ and an exhaust pressure of 1013 mbar. A performance tolerance of ±10% applies.
Q
What transmission methods are available for the 2BE1 vacuum pump series?
Two transmission methods are available: direct connection and V-belt drive. Smaller models such as the 2BE1 103 and 2BE1 153 typically use direct connection, while larger models often offer both options depending on speed and power requirements.
Q
How should I select the correct motor power for a 2BE1 vacuum pump?
The motor power listed is suitable for most standard operating conditions. If the exhaust port pressure is elevated (0.02–0.05 MPa), a higher motor power should be selected. Conversely, if the actual shaft power during normal operation is lower, choosing a motor closer to the shaft power is recommended for better energy efficiency.
Q
Which 2BE1 model offers the highest maximum exhaust volume?
The 2BE1 403 model offers the highest maximum exhaust volume of 123 m³/min (at 200 KW, 472 r.p.m.), with a DN300 intake and exhaust pipe diameter, making it ideal for large-scale industrial processes.
Q
What pipe diameter is required for the 2BE1 303 and 2BE1 353 models?
Both the 2BE1 303 and 2BE1 353 models use DN200 intake and exhaust pipe connections. For the larger 2BE1 403 series, a DN300 pipe diameter is required to accommodate the higher flow volumes.
