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 — including 2BV2, 2BV5, and 2BV6 — can achieve a limit vacuum level of -0.098 MPa (3300 Pa). This consistent vacuum performance across the entire product line makes the 2BV series suitable for a wide range of industrial vacuum applications.
Q
What is the difference between standard models and EX models (e.g., 2BV2061 vs. 2BV2061-EX)?
The EX models (e.g., 2BV2061-EX, 2BV2070-EX, 2BV2071-EX) are explosion-proof versions designed for use in hazardous environments where flammable gases or vapors may be present. They deliver the same exhaust volume and pump speed as their standard counterparts but are fitted with motors that meet explosion-proof safety standards. The EX versions typically have slightly higher motor power ratings to accommodate the certified motor design.
Q
Under what conditions were the performance parameters in the table measured?
The performance data in the table was measured under the following standardized conditions: intake medium — saturated air at 20℃, working fluid (water) temperature at 15℃, and exhaust pressure at 1013 mbar. A performance tolerance of ±10% applies to all listed values. Actual performance may vary depending on site conditions.
Q
How do I select the right model based on required exhaust volume and power?
First, determine the required vacuum level and exhaust volume (m³/min) for your application. Then, refer to the specification table to find a model whose Maximum Exhaust Volume meets or exceeds your requirement. Consider the available power supply and pipe connection size (G-thread or DN flange) to narrow down your selection. For higher flow rates, models such as 2BV5161 or 2BV6161 (15 KW, 8.33 m³/min) are recommended.
Q
What pipe connection standards are used for the 2BV series pumps?
The 2BV2 series models use G-thread pipe connections (G1 or G1 1/2), which are BSP (British Standard Pipe) standard fittings. The 2BV5 and 2BV6 series models use DN flange connections (DN50, DN65, or DN80), which follow metric pipe diameter standards. Please ensure that your piping system matches the corresponding connection standard before installation.
Q
What is the difference between the 2BV5 and 2BV6 series models?
The 2BV5 and 2BV6 series share identical performance specifications — the same power ratings, exhaust volumes, pump speeds, and pipe diameters. The primary difference lies in their construction and material configuration: the 2BV6 series typically features upgraded materials or structural components (such as stainless steel impellers or enhanced corrosion-resistant parts), making them more suitable for demanding or corrosive process environments.
