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 of the 2BE1 series liquid ring vacuum pump?
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 that require deep and stable vacuum performance.
Q2
What are the two transmission methods available for 2BE1 vacuum pumps?
The 2BE1 series offers two transmission methods: Direct connection and V-belt drive. The choice depends on the required pump speed, power, and installation conditions. Direct connection provides higher efficiency, while V-belt drive allows more flexibility in speed adjustment.
Q3
Under what test conditions were the performance parameters in the table measured?
The performance data was measured using saturated air at 20℃ as the intake medium, with a working fluid 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 correct motor power for my 2BE1 vacuum pump?
The listed motor power is suitable for most standard operating conditions. If the exhaust port pressure is elevated (0.02 – 0.05 MPa), you should select a higher motor power. Conversely, if the pump's actual shaft power is lower during normal operation, choosing a motor closer to the actual shaft power will result in greater energy efficiency.
Q5
What pipe diameter is used for the largest 2BE1 403 model?
The 2BE1 403 model uses an intake and exhaust pipe diameter of DN300, the largest among the 2BE1 series. It supports motor powers of 132 kW, 160 kW, and 200 kW, with a maximum exhaust volume of up to 123 m³/min.
Q6
Which 2BE1 model is best suited for smaller-scale applications with lower power requirements?
The 2BE1 103 is the most compact model in the series, requiring only 11 kW of power, with a maximum exhaust volume of 5.8 m³/min and a DN65 pipe diameter. It is ideal for small-scale industrial processes where space and energy consumption are key considerations.
