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 operating normally, a motor power closer to the shaft power can be selected, which is more energy-efficient.

Frequently Asked Questions
Q1
What is the limit vacuum level for the 2BE1 series liquid ring vacuum pumps?
All models in the 2BE1 series achieve a limit vacuum level of -0.098 MPa (3300 Pa), making them suitable for high-vacuum industrial applications such as paper, chemical, and power generation processes.
Q2
What are the two transmission methods available for 2BE1 vacuum pumps?
The 2BE1 series offers two transmission methods: Direct connection (direct coupling to the motor) and V-belt drive. The choice depends on the required pump speed and power configuration for your application.
Q3
Under what conditions were the performance parameters in the table measured?
The listed performance data was 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 listed values.
Q4
How should I select the motor power if the exhaust port pressure is higher than normal?
If the exhaust port pressure is elevated in the range of 0.02 – 0.05 MPa, the motor power should be increased accordingly beyond the standard listed values to ensure reliable and safe operation without overloading the motor.
Q5
Which 2BE1 model offers the highest maximum exhaust volume?
The 2BE1 403 model offers the highest maximum exhaust volume, reaching up to 123 m³/min at 472 r.p.m with a 200 KW motor via V-belt transmission, and features the largest intake/exhaust pipe diameter of DN300.
Q6
Can I select a lower motor power than listed for energy savings?
Yes. If the actual shaft power of the 2BE1 vacuum pump during normal operation is relatively low, you may select a motor with a power rating closer to the actual shaft power. This approach is more energy-efficient and can help reduce operating costs without compromising pump performance.
