Frequently Asked Questions
Q
What is the limit vacuum level that 2BV series liquid ring vacuum pumps can achieve?
All models in the 2BV series — including the 2BV2, 2BV5, and 2BV6 ranges — achieve a limit vacuum level of -0.098 MPa (3300 Pa). This applies uniformly across all listed model numbers in the specification table.
Q
Under what conditions are the performance parameters in the table measured?
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 if operating conditions differ from these standards.
Q
What does the "-EX" suffix mean in models like 2BV2061-EX?
The "-EX" designation indicates an explosion-proof version of the standard model. For example, the 2BV2061-EX has a motor power of 1.5 KW compared to 1.45 KW for the standard 2BV2061, while delivering the same exhaust volume and vacuum level, making it suitable for use in hazardous or flammable environments.
Q
What is the difference between the 2BV5 and 2BV6 series models?
The 2BV5 and 2BV6 series share identical performance specifications in terms of power, maximum exhaust volume, pump speed, and pipe diameters. The primary difference lies in their mechanical construction and material configuration, with the 2BV6 series typically featuring enhanced materials or design suited for more demanding or corrosive applications.
Q
How much performance tolerance should I account for when selecting a model?
According to the manufacturer's specification, the performance tolerance is ±10%. This means actual exhaust volume and power consumption may vary by up to 10% from the values listed in the table. It is recommended to include this margin when engineering your vacuum system design.
Q
Which model should I choose for a higher exhaust volume requirement?
For the highest exhaust volume in this series, the 2BV5161 and 2BV6161 models both offer a maximum exhaust volume of 8.33 m³/min at 15 KW with a pump speed of 970 r.p.m and a DN80 pipe diameter. These are the top-capacity models suitable for large-scale industrial vacuum applications.
