Frequently Asked Questions
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.
What is the difference between 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. They share the same exhaust volume and pump speed as their standard counterparts but are built to meet explosion-proof safety standards.
Under what operating conditions were the performance parameters in the table measured?
The performance parameters were measured with saturated air as the intake medium at 20℃, a working fluid (seal water) temperature of 15℃, and an exhaust pressure of 1013 mbar. Results may vary if operating conditions differ from these standard test conditions.
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 within the 2BV series, with a motor power of 15 KW and a pump speed of 970 r.p.m, connected via DN80 pipe diameter.
What pipe diameter connection is required for the higher-capacity 2BV models?
Higher-capacity models use larger pipe connections: DN50 for models up to 3.83 m³/min, DN65 for models up to 6.66 m³/min, and DN80 for the largest models at 8.33 m³/min. Smaller 2BV2 series models use G1 or G1 1/2 threaded connections.
What is the acceptable performance tolerance for the 2BV series pumps?
The performance tolerance for all 2BV series liquid ring vacuum pumps is ±10%. This means actual performance values such as exhaust volume and vacuum level may vary within this range depending on specific installation conditions and operating environments.
