💬 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 ranges — can achieve a limit vacuum level of -0.098 MPa (3300 Pa), making them suitable for demanding industrial vacuum applications.
Q What do the "-EX" suffix models (e.g., 2BV2061-EX) indicate?
The "-EX" suffix designates explosion-proof versions of the standard 2BV2 series pumps. These models are designed for use in hazardous environments where flammable gases or vapors may be present, and they comply with relevant explosion-proof standards.
Q Under what conditions were the performance parameters in the table measured?
The performance data was obtained using saturated air as the intake medium at 20℃, with a working fluid temperature of 15℃ and an exhaust pressure of 1013 mbar. A performance tolerance of ±10% applies to all listed values.
Q What is the difference between the 2BV5 and 2BV6 series models?
The 2BV5 and 2BV6 series share identical performance parameters (power, exhaust volume, pump speed, and pipe diameters) across corresponding model numbers. The primary differences lie in their construction materials and application suitability — the 2BV6 series typically features enhanced corrosion-resistant materials for more demanding process environments.
Q Which model should I choose for a high-flow vacuum application requiring over 6 m³/min?
For exhaust volumes exceeding 6 m³/min, the recommended models are 2BV5131 / 2BV6131 (6.66 m³/min, 11 KW) or 2BV5161 / 2BV6161 (8.33 m³/min, 15 KW), both equipped with DN65 or DN80 pipe connections respectively.
Q What pipe connection standards are used for the intake and exhaust ports of 2BV pumps?
Smaller models in the 2BV2 series use BSP (British Standard Pipe) threaded connections — G1 or G1 1/2. Larger models in the 2BV5 and 2BV6 series use DN (nominal diameter) flanged connections, including DN50, DN65, and DN80, depending on the model's flow capacity.
