Greentech International (Zhangqiu) Co., Ltd. is a leading supplier of vacuum pumps, offering high-quality and reliable solutions for various industrial applications. Among their product range, the 2BV series water ring vacuum pumps are widely used for pumping gases and steam. These pumps can achieve a suction pressure of up to 33 mbar (ABS), equivalent to a 97% vacuum level. When using transformer oil as the operating liquid, they function as oil ring vacuum pumps, reaching a suction pressure of 6.7 mbar (ABS), or 99% vacuum, making them an ideal replacement for traditional reciprocating vacuum pumps.
For long-term operation near the maximum vacuum level, it's essential to connect a cavitation protection pipe to reduce noise and protect the pump from damage. The 2BV series compressors can handle a maximum discharge pressure of 0.26 MPa (ABS), with higher pressure requiring more powerful motors. Therefore, providing accurate discharge pressure data is crucial when selecting the appropriate motor.
The 2BV2-Ex and 2BV6 series models are specifically designed for use in explosive environments or with flammable gases, featuring the same technical specifications as the standard 2BV2 and 2BV5 series. The stainless steel versions of the 2BV series are ideal for corrosive or high-purity applications, with components such as the pump casing, impeller, and port plate available in materials like SUS304, SUS316, and SUS316L. The shaft is made from 2Cr13 or 0Cr18Ni12Mo2Ti, and mechanical seals are sourced from John Crane, with options for FPM or PTFE.
Key features of the 2BV series include:
- A compact design that saves space and simplifies installation.
- Standard use of John Crane mechanical seals for reliability.
- Cavitation protection ports to prevent damage during low-pressure operations.
- Aluminum bronze impellers for enhanced strength and wear resistance.
- A unique discharge port design that prevents overpressure and ensures optimal performance.
- Motors from the Y2 series with IP54/IP55 protection and insulation class F.
- Bearings from reputable brands like NTN or NSK for durability.
