Performance Parameter 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 (FAQ)
Q
What is the limit vacuum level of the 2BE1 series liquid ring vacuum pump?
The entire 2BE1 series achieves a limit vacuum level of -0.098 MPa (3300 Pa), making it suitable for demanding industrial vacuum applications that require deep and stable vacuum performance.
Q
What transmission methods are available for the 2BE1 vacuum pump?
The 2BE1 series supports 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 often offer both options depending on the required pump speed and power configuration.
Q
Under what test conditions were the performance parameters measured?
All listed performance parameters were measured using saturated air at 20℃ as the intake medium, with a working fluid (water) temperature of 15℃ and an exhaust pressure of 1013 mbar. A performance tolerance of ±10% applies to all values.
Q
How should I select the correct motor power for my 2BE1 vacuum pump?
The motor powers listed in the table cover 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 is lower than rated during normal operation, choosing a motor closer to the actual shaft power will improve energy efficiency.
Q
What is the maximum exhaust volume available in the 2BE1 series?
The largest model in the series, the 2BE1 403, achieves a maximum exhaust volume of 123 m³/min with a 200 KW motor at 472 r.p.m via V-belt transmission, making it ideal for large-scale industrial vacuum systems.
Q
What pipe diameter should I use for the 2BE1 403 model?
The 2BE1 403 requires an intake and exhaust pipe diameter of DN300. Pipe diameter requirements vary across the series — ranging from DN65 for the smallest model (2BE1 103) up to DN300 for the largest — so always match the piping to the specific model selected.
