📋 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 achievable by the 2BE1 series liquid ring vacuum pumps?
All models in the 2BE1 series achieve a limit vacuum level of -0.098 MPa (3300 Pa). This applies consistently across the entire product range, from the 2BE1 103 to the 2BE1 403.
Q
Under what conditions were the performance parameters in the table measured?
The performance data was obtained using 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 offers two transmission methods: Direct connection and V-belt drive. Smaller models such as the 2BE1 103 and 2BE1 153 use direct connection, while larger models offer both options depending on the power and speed configuration required.
Q
How should I select the correct motor power for my 2BE1 vacuum pump application?
The motor power listed in the table is suitable for most standard operating conditions. If your application involves a higher exhaust port pressure (0.02 – 0.05 MPa), you should select a higher motor power accordingly. Conversely, if the actual shaft power during normal operation is low, choosing a motor closer to the shaft power will result in greater energy efficiency.
Q
What are the available intake and exhaust pipe diameter options across the 2BE1 series?
Pipe diameters increase with pump size. The available options are: DN65 (2BE1 103), DN100 (2BE1 153), DN125 (2BE1 202/203), DN150 (2BE1 252/253), DN200 (2BE1 303/353), and DN300 (2BE1 403). Selecting the correct pipe diameter is essential for maintaining optimal system flow and vacuum performance.
Q
Which 2BE1 model offers the highest maximum exhaust volume?
The 2BE1 403 offers the highest maximum exhaust volume in the series, reaching up to 123 m³/min at 200 KW with a pump speed of 472 r.p.m and V-belt transmission. This makes it the most suitable model for large-scale industrial vacuum applications requiring high throughput.
