Greentech International (Zhangqiu) Co., Ltd. is a professional supplier of vacuum pumps, offering high-quality and reliable solutions for various industrial applications. The 2BV series water ring vacuum pumps are ideal for pumping gases and steam, with a suction pressure that can reach up to 33 mbar (ABS), equivalent to a 97% vacuum level. When using transformer oil as the operating liquid, these pumps can achieve an even higher vacuum level of 6.7 mbar (ABS), or 99%, making them a suitable replacement for traditional reciprocating vacuum pumps.
These pumps are commonly used in vacuum filtration, disinfection, and distillation processes. They come in different models, including oil-free and oil-ring versions, and are available with various materials such as cast iron or stainless steel, depending on the application requirements. The pumps feature a close-coupled design, which makes installation easy and saves space. Standard mechanical seals from John Crane are used, ensuring durability and efficiency.
The 2BV2-Ex and 2BV6 series are specifically designed for use in explosive environments, meeting safety standards like dIIBT4. They also include cavitation protection ports to prevent damage when working near the maximum vacuum level. The aluminum bronze impeller ensures high strength and wear resistance, while the unique discharge port design protects against overpressure and maintains optimal performance.
The motors used in these pumps are from the Y2 series, with protection classes IP54 or IP55 and insulation class F. Bearings are imported from reputable brands like NTN or NSK, ensuring long-lasting performance. The pumps are available in different sizes, with specifications varying in terms of suction capacity, motor power, and weight.
Here is a detailed table showing the technical parameters of the 2BV series:
