💬 Frequently Asked Questions
Q
What is the limit vacuum level achievable by the 2BV series liquid ring vacuum pumps?
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 that require deep and stable vacuum performance.
Q
What is the difference between the standard 2BV models and the "-EX" explosion-proof variants?
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. Their exhaust volume and pump speeds remain the same, but the motor ratings are slightly adjusted to meet explosion-proof standards.
Q
Under what test conditions are the performance parameters in the table measured?
The parameters are 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.
Q
What is the performance tolerance for the 2BV series pumps?
The performance tolerance for all 2BV series models is ±10%. This means the actual exhaust volume, power consumption, and pump speed may slightly deviate from the listed values within this acceptable range.
Q
Which 2BV model offers the highest maximum exhaust volume?
Both the 2BV5161 and 2BV6161 models offer the highest maximum exhaust volume of 8.33 m³/min with a power rating of 15 KW and a pump speed of 970 r.p.m, making them ideal for large-scale vacuum applications.
Q
What is the difference between the 2BV5 series and the 2BV6 series?
The 2BV5 series and 2BV6 series share identical performance specifications (power, exhaust volume, pump speed, and pipe diameters). The primary difference lies in their construction and material specifications — the 2BV6 series typically features enhanced material grades or structural configurations suited for more demanding or corrosive operating environments.
