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), making them suitable for high-vacuum industrial applications.
Q
Under what conditions are the performance parameters in the table measured?
A
The parameters are measured with 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.
Q
What transmission methods are available for the 2BE1 vacuum pump series?
A
The 2BE1 series offers two transmission methods: direct connection and V-belt drive. The choice depends on the specific model and required operating speed.
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 the exhaust port pressure is high (0.02–0.05 MPa), you should increase motor power accordingly. For energy efficiency, if the pump's actual shaft power is lower during normal operation, selecting a motor closer to the shaft power is recommended.
Q
Which 2BE1 model offers the highest maximum exhaust volume?
A
The 2BE1 403 model offers the highest maximum exhaust volume of up to 123 m³/min at 200 KW with a pump speed of 472 r.p.m, making it ideal for large-scale industrial vacuum applications.
Q
What pipe diameter is required for the larger 2BE1 models such as the 2BE1 403?
A
The 2BE1 403 requires an intake and exhaust pipe diameter of DN300. Smaller models such as the 2BE1 103 use DN65, while mid-range models like the 2BE1 303 and 2BE1 353 use DN200.
