Performance Parameter 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 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.
Q
Under what conditions were the performance parameters in the table measured?
The parameters were 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 series vacuum pumps?
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 may use either method depending on the required speed and power configuration.
Q
How should I select the correct motor power for a 2BE1 vacuum pump?
The listed motor power covers most standard working conditions. If the exhaust port pressure is elevated (0.02–0.05 MPa), you should increase the motor power accordingly. Conversely, if the actual shaft power is lower during normal operation, selecting a motor closer to the shaft power rating will improve energy efficiency.
Q
Which 2BE1 model offers the highest maximum exhaust volume?
The 2BE1 403 model offers the highest maximum exhaust volume in the series, reaching up to 123 m³/min at 472 r.p.m with a 200 KW motor, and uses a DN300 intake and exhaust pipe diameter.
Q
What intake and exhaust pipe diameters are used across the 2BE1 series?
Pipe diameters vary by model: DN65 for 2BE1 103, DN100 for 2BE1 153, DN125 for 2BE1 202 and 203, DN150 for 2BE1 252 and 253, DN200 for 2BE1 303 and 353, and DN300 for 2BE1 403. Selecting the correct pipe size is essential for optimal system performance.
