Frequently Asked Questions
Q1
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), making them suitable for a wide range of industrial vacuum applications requiring deep and stable vacuum performance.
Q2
What are the standard test conditions for the performance parameters in the table?
The listed performance parameters were measured with saturated air as the intake medium at 20℃, a working fluid temperature of 15℃, and an exhaust pressure of 1013 mbar. Actual performance may vary depending on site conditions.
Q3
What is the performance tolerance for the 2BV series vacuum pumps?
The performance tolerance for all 2BV series models is ±10%. This means the actual exhaust volume, power consumption, and pump speed may deviate by up to 10% from the values listed in the specification table.
Q4
What is the difference between the standard models and the "-EX" explosion-proof models?
The "-EX" models (e.g., 2BV2061-EX, 2BV2070-EX, 2BV2071-EX) are explosion-proof variants designed for use in hazardous environments where flammable gases or vapors may be present. They feature slightly higher motor power ratings compared to their standard counterparts while maintaining the same exhaust volume and pump speed.
Q5
How do I select the right 2BV model based on my required exhaust volume?
Identify your required exhaust volume (m³/min) and match it 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 choices. Also consider your available power supply and required pipe connection sizes when making your selection.
Q6
What pipe connection sizes are available for the 2BV series, and how do I choose the right one?
The 2BV series offers pipe connection sizes including G1, G1 1/2, DN50, DN65, and DN80. Smaller models (2BV2 series) use G1 or G1 1/2 threaded connections, while larger models (2BV5 and 2BV6 series) use DN50 to DN80 flanged connections. Choose based on your existing piping infrastructure and the required flow capacity of your system.
