Water Ring Vacuum Pump (2BV2 070)

Greentech International (Zhangqiu) Co., Ltd. is a professional supplier of vacuum pumps, offering high-quality and reliable solutions for a wide range of industrial applications. The 2BV series water ring vacuum pumps are ideal for handling gases and vapors, with a suction pressure reaching as low as 33 mbar (ABS), which equates to a 97% vacuum level. When using transformer oil as the operating fluid, these pumps function as oil ring vacuum pumps, achieving a suction pressure of 6.7 mbar (ABS), or 99% vacuum efficiency. This makes them a perfect replacement for traditional reciprocating vacuum pumps. When operating under conditions close to the maximum vacuum for extended periods, it's essential to connect a cavitation protection pipe to prevent noise and protect the pump. These pumps can also operate as compressors, with a maximum discharge pressure of 0.26 MPa (ABS). The higher the discharge pressure, the greater the required motor power, so providing accurate pressure data is crucial when selecting the appropriate motor. The 2BV2-Ex and 2BV6 series are specifically designed for use in explosive environments or with flammable gases. Their technical specifications match those of the 2BV2 or 2BV5 series. Stainless steel versions of the 2BV series are suitable for corrosive or clean environments. Key components such as the pump casing, cover, port plate, and impeller are made from various grades of stainless steel, including SUS304 (0Cr18Ni9), SUS316 (0Cr17Ni12Mo2), and SUS316L (00Cr17Ni14Mo2). The shaft material is either 2Cr13 or 0Cr18Ni12Mo2Ti, while mechanical seals are sourced from John Crane, available in FPM or PTFE options. The 2BV series features several key advantages: - **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 working near maximum vacuum. - **Aluminum bronze impeller** for high strength and wear resistance, improving the pump’s durability and corrosion resistance. - **Unique discharge port design** to prevent overpressure and maintain optimal performance. - **Y2 series motors** with IP54/IP55 protection class and F insulation rating. - **High-quality imported bearings** from NTN or NSK for reliability and longevity. These pumps are widely used in chemical processing, pharmaceuticals, food industry, and other sectors where precision and reliability are essential. With a strong focus on quality and innovation, Greentech continues to deliver cutting-edge vacuum solutions that meet global standards.
