Liquid Ring Vacuum Pump 2BV / Water Ring Vacuum Pump

Greentech International (Zhangqiu) Co., Ltd. is a professional supplier of vacuum pumps, offering high-quality and reliable solutions for various industrial applications. Our 2BV series water ring vacuum pumps are designed to efficiently handle gases and steam, with suction pressure reaching as low as 33 mbar (ABS), equivalent to 97% vacuum degree. When using transformer oil as the operating liquid, these pumps can achieve even higher performance, reaching 6.7 mbar (ABS), or 99% vacuum degree, making them a suitable replacement for traditional reciprocating vacuum pumps. These pumps are ideal for environments where high vacuum levels are required, such as in vacuum filtration, disinfection, and distillation processes. The 2BV2-Ex and 2BV6 series models are specifically engineered for use in explosive or flammable environments, ensuring safety and efficiency in hazardous conditions. All technical parameters remain consistent with the corresponding 2BV2 or 2BV5 series products. The 2BV stainless steel pump models are particularly suited for corrosive or high-purity environments, with key components like the pump casing, impeller, and port plate made from materials such as SUS304, SUS316, and SUS316L. The shaft is constructed from 2Cr13 or 0Cr18Ni12Mo2Ti, while mechanical seals are sourced from John Crane, available in FPM or PTFE options for enhanced durability and sealing performance. Key features of the 2BV series include: - **Close-coupled design** for easy installation and space-saving. - **Standard John Crane mechanical seals** for long-lasting performance. - **Cavitation protection port** to prevent damage when operating near maximum vacuum levels. - **Aluminum bronze impellers** for improved strength and wear resistance. - **Unique discharge port design** to protect against overpressure and maintain optimal efficiency. - **High-quality motors** from the Y2 series, with IP54/IP55 protection ratings and insulation class F. - **Imported NTN or NSK bearings** for smooth and reliable operation.
