Frequently Asked Questions
Q
What is the limit vacuum level that the 2BV series liquid ring vacuum pumps can achieve?
All models in the 2BV series can achieve a limit vacuum level of -0.098 MPa (3300 Pa). This applies to the full range including 2BV2, 2BV5, and 2BV6 series models.
Q
What are the test conditions for the performance parameters listed in the table?
The listed performance data was 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 listed values.
Q
What is the difference between standard models (e.g., 2BV2061) and EX models (e.g., 2BV2061-EX)?
The -EX suffix denotes explosion-proof versions of the pump. These models are designed for use in hazardous or flammable environments. The exhaust volume and pump speed remain the same, but the motor power rating may differ slightly to meet explosion-proof standards.
Q
Which model should I choose if I need a higher exhaust volume?
For higher exhaust volumes, consider the larger models such as 2BV5161 or 2BV6161, which offer a maximum exhaust volume of 8.33 m³/min with a 15 KW motor. Models with DN65 or DN80 pipe diameters generally support higher flow rates.
Q
What pipe connection sizes are available for the 2BV series vacuum pumps?
The 2BV series offers multiple pipe connection options depending on the model: G1 and G1 1/2 for the 2BV2 series, and DN50, DN65, and DN80 for the 2BV5 and 2BV6 series. Always select a model whose pipe diameter matches your system's piping design.
Q
What is the difference between the 2BV5 series and the 2BV6 series?
The 2BV5 and 2BV6 series share identical power ratings, exhaust volumes, pump speeds, and pipe diameters across corresponding models. The primary difference lies in their construction material and design configuration, making the 2BV6 series more suitable for applications requiring higher corrosion resistance or specific installation requirements.
