Greentech International (Zhangqiu) Co., Ltd. is a leading supplier of vacuum pumps, offering high-quality and reliable solutions for industrial applications. Our 2BV series water ring vacuum pumps are ideal for handling gases and steam, with a suction pressure capability of up to 33 mbar (ABS), equivalent 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 complete replacement for traditional reciprocating vacuum pumps.
In environments where the pump operates near its maximum vacuum capacity for extended periods, it is recommended to install a cavitation protection pipe to prevent noise and protect the pump from damage. During compression operations, the maximum discharge pressure can reach 0.26 MPa (ABS). The higher the discharge pressure, the more power the compressor requires, so providing accurate discharge pressure data is essential when selecting the appropriate motor.
The 2BV2-Ex and 2BV6 series water ring vacuum pumps and compressors are specifically designed for use in explosive gas environments or flammable areas. Their technical specifications match those of the 2BV2 and 2BV5 series products. Additionally, our stainless steel 2BV series pumps are suitable for applications requiring high corrosion resistance and cleanliness.
All internal components that come into contact with liquid—such as the pump casing, cover, port plate, and impeller—are available in various grades of stainless steel, including SUS304 (0Cr18Ni9), SUS316 (0Cr17Ni12Mo2), and SUS316L (00Cr17Ni14Mo2). The shaft material is either 2Cr13 or 0Cr18Ni12Mo2Ti, ensuring durability and performance. Mechanical seals are sourced from John Crane, with options for FPM or PTFE materials to suit different application needs.
Our 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 reduce noise and protect the pump under high vacuum conditions.
- **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 rating and F-class insulation for reliability.
- **Imported bearings** from reputable brands like NTN or NSK for smooth operation.
Whether you're looking for a standard vacuum pump or a specialized model for harsh environments, Greentech offers a comprehensive range of solutions tailored to your needs. With years of experience and a commitment to quality, we deliver products that meet international standards and exceed customer expectations.
