❓ 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 demanding industrial vacuum applications.
Q
What are the operating conditions under which the performance parameters are measured?
The performance 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. A performance tolerance of ±10% applies.
Q
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. They operate at slightly higher power ratings compared to their standard counterparts while maintaining the same exhaust volume and pump speed.
Q
Which 2BV model offers the highest maximum exhaust volume?
The models 2BV5161 and 2BV6161 offer the highest maximum exhaust volume of 8.33 m³/min, both powered at 15 KW with a pump speed of 970 r.p.m and a DN80 pipe diameter.
Q
What is the difference between the 2BV5 series and the 2BV6 series?
The 2BV5 and 2BV6 series share identical performance specifications (power, exhaust volume, pump speed, and pipe diameters). The primary differences lie in their mechanical construction and material options, allowing selection based on specific application requirements such as corrosion resistance or structural compatibility.
Q
How do I select the right 2BV vacuum pump model for my application?
Selection should be based on the required exhaust volume (m³/min), available power supply (KW), and the vacuum level needed. For hazardous or explosive environments, choose the "-EX" explosion-proof variants. Also consider the pipe diameter (G1, DN50, DN65, DN80) to ensure compatibility with your existing piping system.
