    i 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 achieve a limit vacuum level of -0.098 MPa (3300 Pa). This consistent vacuum level applies across all listed models, from the 2BE1 103 to the 2BE1 403, making this series suitable for high-vacuum industrial applications.
    Q What transmission methods are available for the 2BE1 series pumps?
    The 2BE1 series pumps support two transmission methods: Direct connection and V-belt drive. Smaller models such as the 2BE1 103, 153, 202, and 203 use direct connection, while larger models often offer both options depending on the required pump speed and power configuration.
    Q Under what standard conditions were the performance parameters measured?
    The performance parameters in the table were measured under specific standard conditions: the intake medium is saturated air at 20℃, the working fluid temperature is 15℃, and the exhaust pressure is 1013 mbar. Results may vary outside of these conditions.
    Q What is the performance tolerance for the 2BE1 series specifications?
    The performance tolerance for all 2BE1 series vacuum pumps is ±10%. This means actual exhaust volume, pump speed, and power consumption may deviate by up to 10% from the values listed in the specification table under real operating conditions.
    Q How should I select the appropriate motor power for a 2BE1 vacuum pump?
    Motor power selection depends on actual working conditions. The listed motor power covers most standard applications. If the exhaust port pressure is high (between 0.02–0.05 MPa), a higher motor power should be selected. Conversely, if the shaft power is relatively low during normal operation, choosing a motor power closer to the actual shaft power improves energy efficiency.
    Q What are the intake and exhaust pipe diameter options across the 2BE1 series?
    Pipe diameters vary by model size: the 2BE1 103 uses DN65, the 2BE1 153 uses DN100, models 2BE1 202 and 203 use DN125, models 2BE1 252 and 253 use DN150, models 2BE1 303 and 353 use DN200, and the largest model, 2BE1 403, uses DN300. Selecting the correct pipe diameter is critical for optimal flow performance.
