Greentech International (Zhangqiu) Co., Ltd is a professional supplier of vacuum pumps, offering high-quality and reliable solutions for various industrial applications. Among our product lines, the 2BV series water ring vacuum pumps are widely used in industries such as CNC routers, vacuum filtration, disinfection, and distillation. These pumps are designed to handle gases and steam efficiently, with suction pressures reaching up to 33 mbar (ABS), equivalent to a 97% vacuum level. When using transformer oil as the operating fluid, they can achieve even higher performance, reaching 6.7 mbar (ABS), or 99% vacuum.
The 2BV series includes both oil-free and oil-ring versions, making them suitable for different environments. The oil-free models are ideal for applications where contamination must be avoided, while the oil-ring versions offer enhanced vacuum performance. For explosive or flammable environments, the 2BV2-Ex and 2BV6 series are specifically designed with explosion-proof motors and protection ratings like IP54 or IP55, ensuring safe operation under hazardous conditions.
These pumps are available in various materials, including cast iron and stainless steel options (SUS304, SUS316, SUS316L), allowing them to perform well in corrosive or high-purity settings. The impellers are made from aluminum bronze, providing excellent strength and wear resistance. Additionally, mechanical seals from John Crane are used, with optional materials such as FPM or PTFE for enhanced sealing performance.
Key features of the 2BV series include:
- A compact, close-coupled design that saves space and simplifies installation.
- Standard use of John Crane mechanical seals for long-lasting performance.
- A cavitation protection port that prevents damage when operating near the maximum vacuum level.
- An optimized discharge port design that protects against overpressure and ensures efficient operation.
- High-quality Y2 series motors with IP54/IP55 protection and F-class insulation.
- Bearings from reputable brands like NTN or NSK for smooth and durable operation.
