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 the 2BV2, 2BV5, and 2BV6 lines — achieve a limit vacuum level of -0.098 MPa (3300 Pa). This consistent vacuum performance applies across all listed models regardless of power rating or pump speed.
Q
What do the "-EX" models (e.g., 2BV2061-EX) indicate, and how do they differ from standard models?
The -EX designation indicates explosion-proof versions of the corresponding standard models. For example, the 2BV2061-EX operates at 1.5 KW compared to the standard 2BV2061 at 1.45 KW, while maintaining the same exhaust volume, pump speed, and pipe diameter. These models are designed for use in hazardous or potentially explosive environments.
Q
Under what conditions were the performance parameters measured?
The performance parameters in the table were measured under the following standard conditions: saturated air as the intake medium at 20℃, working fluid temperature at 15℃, and exhaust pressure at 1013 mbar. Actual performance may vary depending on site-specific operating conditions.
Q
What is the maximum exhaust volume available in the 2BV series?
The highest maximum exhaust volume in this series is 8.33 m³/min, available in both the 2BV5161 and 2BV6161 models, each powered by 15 KW motors operating at 970 r.p.m with DN80 pipe connections.
Q
What is the performance tolerance for these vacuum pumps?
The stated performance tolerance for all 2BV series models is ±10%. This means actual exhaust volume and other performance metrics may deviate by up to 10% from the values listed in the specification table.
Q
What is the difference between 2BV5 and 2BV6 series models with the same power rating?
The 2BV5 and 2BV6 series share identical performance specifications — the same power ratings, maximum exhaust volumes, pump speeds, and pipe diameters — for their corresponding model numbers (e.g., 2BV5110 vs. 2BV6110). The primary differences lie in their mechanical construction and casing materials, making them suitable for different application environments. The 2BV6 series typically features a more robust build for demanding industrial conditions.
