    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%.

    Frequently Asked Questions
    Q What does the model suffix "-EX" mean in the 2BV series vacuum pump models?
    The "-EX" suffix indicates an explosion-proof version of the standard model. For example, 2BV2061-EX is the explosion-proof variant of 2BV2061, designed for use in hazardous environments where flammable gases or vapors may be present. These models comply with relevant explosion-proof standards and are suitable for chemical, petrochemical, and other safety-critical industries.
    Q What is the limit vacuum level achievable by the 2BV series liquid ring vacuum pumps?
    All models in the 2BV series can achieve a limit vacuum level of -0.098 MPa (equivalent to 3300 Pa absolute pressure). This applies uniformly across all listed models, from the compact 2BV2061 to the larger 2BV6161, making them suitable for applications requiring deep vacuum conditions.
    Q Under what conditions were the performance parameters in the table measured?
    The performance data in the specification table was measured under the following standard conditions: intake medium of saturated air at 20°C, working fluid (seal liquid) temperature at 15°C, and exhaust pressure at 1013 mbar (standard atmospheric pressure). Actual performance may vary if operating conditions differ from these standards. A performance tolerance of ±10% applies to all listed values.
    Q How do I select the right 2BV model based on my required exhaust volume?
    To select the correct model, first determine the required maximum exhaust volume (m³/min) for your application. Then refer to the "Maximum exhaust volume" column in the specification table. For example, if you need approximately 4.66 m³/min, models 2BV5121 or 2BV6121 would be appropriate. Also consider available power supply, pipe connection size (G-thread or DN flange), and whether an explosion-proof version is required.
    Q What is the difference between the 2BV5 series and the 2BV6 series?
    The 2BV5 and 2BV6 series share the same performance parameters — identical power ratings, exhaust volumes, pump speeds, and pipe diameters for corresponding model numbers. The primary difference lies in the pump body material and construction design. The 2BV6 series typically features a cast iron pump body, offering enhanced durability and is often preferred for more demanding or corrosive operating environments, while the 2BV5 series is the standard configuration.
    Q What type of pipe connection is used for larger 2BV models, and why does it differ from smaller models?
    Smaller models such as 2BV2061 and 2BV2070 use G-thread (BSP) pipe connections (G1 or G1 1/2), which are standard for lower-flow applications. Larger models in the 2BV5 and 2BV6 series use DN flange connections (DN50, DN65, DN80), which are better suited for higher exhaust volumes and provide more secure, leak-resistant connections in industrial piping systems. The pipe size increases proportionally with the pump's exhaust capacity.
