    📋 Performance Parameter Notes

    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.

    Note 2: The performance tolerance is ±10%.

    Note 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 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 demanding industrial vacuum applications that require deep, stable vacuum performance.
    Q Under what conditions are the performance parameters in the table measured?
    The listed performance parameters are measured with saturated air as the intake medium at 20℃, a working fluid temperature of 15℃, and an exhaust pressure of 1013 mbar. A performance tolerance of ±10% applies to all values.
    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. Smaller models such as the 2BE1 103 and 2BE1 153 use direct connection, while larger models may offer both options depending on the required pump speed and power configuration.
    Q How should I select the correct motor power for my application?
    The motor power in the table is suitable for most standard working conditions. If the exhaust port pressure is high (between 0.02 – 0.05 MPa), you should select a higher motor power accordingly. Conversely, if the actual shaft power during normal operation is lower, choosing a motor closer to the shaft power can improve energy efficiency.
    Q Which 2BE1 model offers the highest maximum exhaust volume?
    The 2BE1 403 model offers the highest maximum exhaust volume in this series, reaching up to 123 m³/min at 200 KW motor power with a pump speed of 472 r.p.m, connected via V-belt drive. It uses DN300 intake and exhaust pipe diameters.
    Q Can the 2BE1 vacuum pump handle varying exhaust port pressures?
    Yes, the 2BE1 series is designed to accommodate varying exhaust port pressures. However, when the exhaust port pressure exceeds standard conditions (up to 0.02 – 0.05 MPa higher), it is recommended to increase the motor power selection to ensure reliable operation and prevent motor overload.
