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 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 reach a limit vacuum level of -0.098 MPa (3300 Pa), making them suitable for demanding industrial vacuum applications.
Q
Under what test conditions were the performance parameters in the table measured?
The parameters were measured using saturated air as the intake medium at 20℃, a working fluid temperature of 15℃, and an exhaust pressure of 1013 mbar. The tolerance for all listed values is ±10%.
Q
What transmission methods are available for the 2BE1 series pumps?
The 2BE1 series offers two transmission methods: direct connection and V-belt drive. Smaller models (2BE1 103 – 2BE1 203) typically use direct connection, while larger models may use either V-belt or direct connection depending on the required pump speed and power.
Q
How should I select the correct motor power for a 2BE1 vacuum pump?
The motor power listed in the table covers most standard operating 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 during normal operation is relatively low, selecting a motor closer to the actual shaft power 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 V-belt transmission, with DN300 intake and exhaust pipe diameters.
Q
What are the intake and exhaust pipe diameter options across the 2BE1 series?
The intake and exhaust pipe diameters vary by model: DN65 (2BE1 103), DN100 (2BE1 153), DN125 (2BE1 202–203), DN150 (2BE1 252–253), DN200 (2BE1 303–353), and DN300 (2BE1 403), allowing flexible integration into different piping systems.
