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 it is operating normally, a motor power closer to the shaft power can be selected, which is more energy-efficient.

Frequently Asked Questions (FAQ)
Q
What is the limit vacuum level of 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 high-vacuum industrial applications such as paper pulp, chemical, power, and mining processes.
Q
What transmission methods are available for the 2BE1 vacuum pump?
The 2BE1 series supports two transmission methods: Direct connection and V-belt drive. The appropriate method depends on the selected model and the required pump speed. Direct connection offers higher transmission efficiency, while V-belt drive allows for flexible speed adjustment.
Q
Under what conditions were the performance parameters measured?
The listed performance data was tested under standardized conditions: saturated air as intake medium at 20℃, working fluid temperature at 15℃, and exhaust pressure at 1013 mbar. A tolerance of ±10% applies to all listed values.
Q
How should I select the correct motor power for my application?
The standard motor power listed covers most working conditions. If your exhaust port pressure is elevated (0.02 – 0.05 MPa), you should select a higher motor power. Conversely, if the actual shaft power during normal operation is low, choosing a motor closer to the shaft power rating is recommended for improved energy efficiency.
Q
What is the maximum exhaust volume available in the 2BE1 series?
The largest model in the table, 2BE1 403, achieves a maximum exhaust volume of 123 m³/min at 200 KW motor power and 472 r.p.m pump speed, with DN300 pipe diameters — making it ideal for large-scale industrial vacuum requirements.
Q
What pipe diameter should I use for different 2BE1 models?
Pipe diameters scale with the model size: 2BE1 103 uses DN65, 2BE1 153 uses DN100, 2BE1 202/203 uses DN125, 2BE1 252/253 uses DN150, 2BE1 303/353 uses DN200, and 2BE1 403 uses DN300. Always match the pipe diameter to the model specification to ensure optimal flow performance.
