China-2xz-B-Series-Direct-Drive-Two-Stage-High-Speed-Rotary-Vane-Vacuum-Pump

**Overview and Application Scope** The 2XZ-B is a newly developed, double-stage, high-speed, and directly-coupled rotary vane vacuum pump. It is designed for a wide range of industrial and scientific applications where reliable and efficient vacuum generation is required. One of its key features is the integrated gas ballast valve, which effectively prevents moisture from mixing with the pump oil, thereby extending the service life of the oil and maintaining optimal performance. Even when the gas ballast valve is open, the pump can still achieve a high level of ultimate vacuum, ensuring consistent and stable operation under various conditions. Designed with an advanced structure similar to international counterparts, the 2XZ-B offers a compact size, lightweight construction, low noise levels, and easy starting capabilities. These characteristics make it ideal for use in environments where space and operational efficiency are critical. Equipped with an oil pumping mechanism, the pump supports both forced and automatic oil feeding systems. This design allows it to operate efficiently even when exposed to atmospheric pressure, making it highly versatile. The pump is also oil-free in terms of return, meaning it does not release oil vapors into the atmosphere, making it environmentally friendly and suitable for clean-room or sensitive application areas. It can be used as a standalone vacuum pump or as a fore pump for booster pumps, diffusion pumps, molecular pumps, and other types of vacuum systems. Additionally, it can function as a holding pump or pre-pump for titanium pumps, enhancing overall system performance. The 2XZ-B is widely applied in the manufacturing of vacuum devices, medical analytical instruments, and specialized equipment. It is particularly well-suited for use in the lithium bromide absorption refrigeration industry, air conditioning systems, and refrigeration applications where consistent and reliable vacuum performance is essential. With its robust design, user-friendly operation, and broad application range, the 2XZ-B is an excellent choice for professionals seeking a high-performance, durable, and environmentally responsible vacuum solution.
