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 achievable by the 2BE1 series liquid ring vacuum pumps?
A
All models in the 2BE1 series can achieve a limit vacuum level of -0.098 MPa (3300 Pa). This applies uniformly across all listed models from 2BE1 103 to 2BE1 403, making them suitable for high-vacuum industrial applications.
Q
What are the test conditions for the performance parameters in the table?
A
The performance data is based on saturated air as the intake medium at 20℃, a working fluid temperature of 15℃, and an exhaust pressure of 1013 mbar. Actual performance may vary depending on site conditions.
Q
What transmission methods are available for the 2BE1 vacuum pump series?
A
The 2BE1 series supports two transmission methods: Direct connection and V-belt drive. Smaller models typically use direct connection, while larger or variable-speed configurations may use V-belt transmission for flexibility.
Q
How should I select the correct motor power for my 2BE1 vacuum pump?
A
The listed motor power covers most standard 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 is lower during normal operation, choosing a motor closer to the shaft power rating improves energy efficiency.
Q
What is the maximum exhaust volume available in the 2BE1 series?
A
The highest maximum exhaust volume in the series is 123 m³/min, achieved by the 2BE1 403 model at 200 KW with a pump speed of 472 r.p.m. This makes the 2BE1 403 ideal for large-scale industrial vacuum applications.
Q
What pipe diameter is required for the larger 2BE1 models?
A
Larger models require wider pipe connections to handle greater gas volumes. The 2BE1 403 requires DN300 intake and exhaust pipe diameters, while mid-range models like 2BE1 303 and 2BE1 353 use DN200. Smaller models range from DN65 to DN150 depending on the specific configuration.
