    Important 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.

    2. The performance tolerance is ±10%.

    Frequently Asked Questions
    Q
    What is the difference between 2BV2 series and 2BV5/2BV6 series pumps?
    The 2BV2 series (e.g., 2BV2061, 2BV2070, 2BV2071) are smaller, higher-speed pumps running at 2840–2880 r.p.m. with G-thread pipe connections, suited for lower flow applications. The 2BV5 and 2BV6 series operate at lower speeds (970–1440 r.p.m.) with DN-standard flanged connections and are designed for higher exhaust volumes up to 8.33 m³/min.
    Q
    What does the "-EX" suffix mean in models like 2BV2061-EX?
    The "-EX" suffix indicates an explosion-proof version of the pump. These models are designed and certified for use in hazardous environments where flammable gases, vapors, or dust may be present, making them suitable for chemical, petroleum, and mining industries.
    Q
    What is the ultimate vacuum level these pumps can achieve?
    All models listed in the table share the same limit vacuum level of -0.098 MPa (3300 Pa). This applies uniformly across the entire 2BV2, 2BV5, and 2BV6 series, making them suitable for a wide range of industrial vacuum applications.
    Q
    Under what conditions are the performance parameters measured?
    The performance parameters in the table are measured under standardized test conditions: saturated air as the intake medium at 20℃, working fluid (water) temperature at 15℃, and an exhaust pressure of 1013 mbar (standard atmospheric pressure). Actual performance may vary based on site conditions.
    Q
    What is the acceptable performance tolerance for these pumps?
    The performance tolerance for all 2BV series liquid ring vacuum pumps is ±10%. This means the actual exhaust volume, power consumption, and vacuum level may deviate by up to 10% from the published specifications under real operating conditions.
    Q
    What pipe connection standards are used for the 2BV series pumps?
    The 2BV2 series uses BSP G-thread pipe connections (G1 or G1 1/2), which are common in smaller-diameter plumbing applications. The 2BV5 and 2BV6 series use DN (Nominal Diameter) flanged connections — specifically DN50, DN65, and DN80 — depending on the model's exhaust capacity, in line with international piping standards.
