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 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 that the 2BE1 series liquid ring vacuum pumps can achieve?
All models in the 2BE1 series can achieve a limit vacuum level of -0.098 MPa (3300 Pa), making them suitable for demanding industrial vacuum applications that require deep and stable vacuum performance.
Q
Under what test conditions were the performance parameters in the table measured?
The listed parameters were measured using saturated air at 20℃ as the intake medium, with a working fluid temperature of 15℃ and an exhaust pressure of 1013 mbar. Actual performance may vary depending on site conditions. A 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. The choice depends on the specific model and operating speed requirement. Smaller models such as the 2BE1 103 to 2BE1 203 typically use direct connection, while larger models may offer both options.
Q
How should I select the motor power when the exhaust port pressure is elevated?
If the exhaust port pressure is higher than standard — typically in the range of 0.02 to 0.05 MPa — it is necessary to select a motor with increased power beyond what is listed in the standard table to ensure reliable operation and avoid overloading the motor.
Q
Can I choose a lower motor power for energy-saving purposes?
Yes. If the shaft power of the 2BE1 vacuum pump is relatively low under normal operating conditions, you may select a motor power rating that is closer to the actual shaft power. This approach is more energy-efficient and helps reduce operating costs without compromising performance.
Q
What pipe diameter should I use for the 2BE1 403 model?
The 2BE1 403 model requires an intake and exhaust pipe diameter of DN300. It is available in three power configurations — 132 kW, 160 kW, and 200 kW — with maximum exhaust volumes ranging from 95 to 123 m³/min, making it one of the highest-capacity models in the 2BE1 series.
