    ⓘ Note: 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 achievable by the 2BE1 series liquid ring vacuum pumps?
    All models in the 2BE1 series can achieve a limit vacuum level of -0.098 MPa (3300 Pa) under standard operating conditions, making them suitable for high-vacuum industrial applications.
    Q Under what conditions are the performance parameters in the table measured?
    The listed performance parameters are obtained under the following standard conditions: saturated air as the intake medium at 20℃, working fluid temperature at 15℃, and exhaust pressure at 1013 mbar. Deviations from these conditions may affect actual performance.
    Q What transmission methods are available for the 2BE1 vacuum pump series?
    The 2BE1 series supports two transmission methods: Direct connection and V-belt drive. The choice depends on the model and the required pump speed (r.p.m). Smaller models typically use direct connection, while larger models may use either method depending on the application.
    Q How should I select the correct motor power for a 2BE1 vacuum pump?
    The standard motor power listed in the table is suitable for most operating conditions. However, if the exhaust port pressure is high (0.02–0.05 MPa), you should select a higher motor power accordingly. Conversely, if the pump's actual shaft power is lower than rated during normal operation, choosing a motor closer to the shaft power will improve energy efficiency.
    Q What is the performance tolerance for the 2BE1 series vacuum pumps?
    The performance tolerance for all models in the 2BE1 series is ±10%. This means actual exhaust volume and power consumption may slightly vary from the tabulated values depending on manufacturing tolerances and real-world operating conditions.
    Q Which 2BE1 model offers the highest maximum exhaust volume, and what are its specifications?
    The 2BE1 403 model offers the highest maximum exhaust volume in this series, reaching up to 123 m³/min with a motor power of 200 KW and a pump speed of 472 r.p.m. It uses V-belt transmission and features DN300 intake and exhaust pipe diameters, making it ideal for large-scale industrial vacuum applications.
