Overview
The 2BV series water ring vacuum pump is designed for pumping air mixed with water vapor. It can achieve an absolute pressure of up to 33 mbar, which corresponds to a vacuum level of approximately 97%. When operating under conditions close to the limit vacuum (i.e., the saturation vapor pressure of the working fluid), it is recommended to connect a cavitation protection tube to prevent damage and ensure optimal performance. As a compressor, the maximum pressure it can handle is up to 0.26 MPa (absolute pressure).
This new generation of energy-efficient pumps offers superior performance and numerous advantages, making them ideal replacements for older models such as SK, 2SK, W, WY, and WL series pumps. The 2BV series is widely used in various industrial applications due to its reliability, efficiency, and durability.
Main Features
1. Direct coupling design saves space and simplifies installation and maintenance.
2. All models are equipped with a cavitation protection tube, ensuring efficient suction even during cavitation by connecting a separator or opening the tube.
3. Stainless steel impellers are available, offering high strength, durability, and improved corrosion resistance.
4. A unique flexible air outlet design prevents over-compression, ensuring optimal performance and efficiency.
5. Equipped with Y2 series motors featuring IP54/IP55 protection (IP44 for standard models) and insulation class F (class B for standard models).
6. Flexible seals made from PTFE significantly extend the pump's service life in harsh environments.
