Frequently Asked Questions
Q
What is the ultimate vacuum level that the 2BV series liquid ring vacuum pumps can achieve?
All models in the 2BV series — including the 2BV2, 2BV5, and 2BV6 lines — achieve a limit vacuum level of -0.098 MPa (3300 Pa). This consistent vacuum performance across the entire range makes the series suitable for a wide variety of industrial vacuum applications.
Q
What are the differences between the 2BV2, 2BV5, and 2BV6 model series?
The 2BV2 series covers smaller capacities (power range 1.45–3.85 KW, exhaust volume up to 1.83 m³/min) and operates at higher speeds (~2840–2880 r.p.m). The 2BV5 and 2BV6 series cover larger capacities (power range 4–15 KW, exhaust volume up to 8.33 m³/min) and run at lower speeds (~970–1460 r.p.m), offering higher flow rates for more demanding applications.
Q
What do the "-EX" suffix models (e.g., 2BV2061-EX) indicate?
The -EX designation indicates explosion-proof versions of the standard 2BV2 models. These variants are designed for use in hazardous environments where flammable gases or vapors may be present. They have slightly higher power ratings compared to their standard counterparts while maintaining the same exhaust volume and pump speed.
Q
Under what conditions were the performance parameters in the table measured?
The performance data in the table was measured under the following standard conditions: saturated air as the intake medium at 20℃, working fluid (water) temperature at 15℃, and exhaust pressure at 1013 mbar. Actual performance may vary depending on site conditions. A tolerance of ±10% applies to all listed performance values.
Q
What pipe connection sizes are available for the 2BV series pumps?
The intake and exhaust pipe diameters vary by model size. Smaller 2BV2 models use G1 or G1 1/2 threaded connections. Larger 2BV5 and 2BV6 models use flanged connections: DN50 (for 4–5.5 KW models), DN65 (for 7.5–11 KW models), and DN80 (for 15 KW models).
Q
What is the maximum exhaust volume available in the 2BV series, and which model provides it?
The maximum exhaust volume in the 2BV series is 8.33 m³/min, achieved by both the 2BV5161 and 2BV6161 models. Both operate at 15 KW power and 970 r.p.m pump speed with DN80 pipe connections, making them the highest-capacity options in the entire 2BV product range.
