Greentech International (Zhangqiu) Co., Ltd. is a professional supplier of vacuum pumps, offering high-quality and reliable solutions for various industrial applications. The 2BV series water ring vacuum pumps are designed to handle gases and steam efficiently. They can achieve a suction pressure of up to 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, capable of reaching a suction pressure of 6.7 mbar (ABS), or 99% vacuum. This makes them a suitable replacement for traditional reciprocating vacuum pumps.
In cases where the pump operates near its maximum vacuum capacity for extended periods, it is recommended to install a cavitation protection pipe to reduce noise and protect the pump from damage. When used as compressors, the maximum discharge pressure reaches 0.26 MPa (ABS). The higher the discharge pressure, the more power the compressor requires, so providing accurate pressure data is essential when selecting the appropriate motor.
The 2BV2-Ex and 2BV6 series water ring vacuum pumps and compressors are ideal for handling explosive gases or operating in flammable environments. Their technical specifications are similar to those of the 2BV2 or 2BV5 series models. Stainless steel versions of the 2BV series are suitable for applications requiring corrosion resistance and cleanliness.
All internal components that come into contact with the liquid—such as the pump casing, cover, port plate, and impeller—are made from different types of stainless steel, including SUS304 (0Cr18Ni9), SUS316 (0Cr17Ni12Mo2), and SUS316L (00Cr17Ni14Mo2). The shaft is typically made from 2Cr13 or 0Cr18Ni12Mo2Ti. Mechanical seals are sourced from John Crane, and materials such as FPM or PTFE can be selected based on application needs.
The 2BV series products feature 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 and reduce noise when operating near the limit vacuum.
- **Aluminum bronze impeller** for high strength and wear resistance, enhancing the pump's durability.
- **Unique discharge port design** to prevent overpressure and ensure optimal efficiency.
- **Y2 series motors** with IP54/IP55 protection class (standard IP44) and F insulation grade.
- **Imported bearings** from NTN or NSK for reliable operation.
These features make the 2BV series a versatile and durable choice for a wide range of industrial vacuum and compression applications. Whether you need a standard model or a specialized version for harsh environments, Greentech offers tailored solutions to meet your needs.
