    ? Frequently Asked Questions
    Q What is the limit vacuum level for the 2BV series liquid ring vacuum pumps?
    All models in the 2BV series achieve a limit vacuum level of -0.098 MPa (3300 Pa), making them suitable for applications requiring deep vacuum performance.
    Q What are the test conditions used to measure the performance parameters?
    The listed performance parameters were measured with saturated air as the intake medium at 20℃, a working fluid temperature of 15℃, and an exhaust pressure of 1013 mbar. A tolerance of ±10% applies to all performance values.
    Q What is the difference between the standard models and the -EX models (e.g., 2BV2061 vs. 2BV2061-EX)?
    The -EX models (such as 2BV2061-EX, 2BV2070-EX, 2BV2071-EX) are explosion-proof versions designed for use in hazardous or flammable environments. They share the same exhaust volume and pump speed as their standard counterparts but are equipped with motors rated for higher power input to comply with explosion-proof standards.
    Q What pipe connection sizes are available across the 2BV series?
    The intake and exhaust pipe diameters vary by model: smaller models (2BV2061 series) use G1 or G1 1/2 threaded connections, while larger models (2BV5 and 2BV6 series) use flanged connections ranging from DN50 and DN65 up to DN80.
    Q What is the maximum exhaust volume available in the 2BV series?
    The highest maximum exhaust volume in the series is 8.33 m³/min, achieved by the 2BV5161 and 2BV6161 models, both rated at 15 kW power.
    Q What is the difference between the 2BV5 and 2BV6 series models?
    The 2BV5 and 2BV6 series share identical performance specifications — the same power ratings, exhaust volumes, pump speeds, and pipe diameters across corresponding models. The key difference lies in the material construction and configuration of the pump body, with the 2BV6 series typically designed for more demanding or corrosion-resistant application requirements.
