Greentech International (Zhangqiu) Co., Ltd is a leading supplier of high-quality vacuum pumps. The 2BV series water ring vacuum pumps are ideal for handling gases and steam, with a suction pressure as low as 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. This makes them a complete 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. During compression operations, the maximum discharge pressure can reach up to 0.26 MPa (ABS). Higher discharge pressure requires more powerful motors, so it's essential to provide the discharge pressure data when selecting the appropriate motor.
The 2BV2-Ex and 2BV6 series water ring vacuum pumps and compressors are designed for use in explosive environments or with flammable gases. Their technical specifications match those of the 2BV2 or 2BV5 series products. The 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 housing, cover, port plate, and impeller—are available in different grades of stainless steel, including:
- SUS304 (0Cr18Ni9)
- SUS316 (0Cr17Ni12Mo2)
- SUS316L (00Cr17Ni14Mo2)
The shaft material is either 2Cr13 or 0Cr18Ni12Mo2Ti. Mechanical seals are sourced from John Crane, and options include FPM or PTFE materials depending on the application.
Key features of the 2BV series include:
- **Compact Design:** Easy to install and space-saving.
- **Standard Seals:** Equipped with John Crane mechanical seals for reliability.
- **Cavitation Protection Port:** Automatically activates under high vacuum conditions to prevent damage.
- **Aluminum Bronze Impeller:** High strength and wear-resistant, enhancing the pump’s durability.
- **Discharge Port Design:** Prevents overpressure and ensures optimal performance across the working range.
- **Motor Options:** Y2 series motors with IP54/IP55 protection rating and Class F insulation.
- **Bearings:** Imported NTN or NSK bearings for long-lasting operation.
Whether you need a standard vacuum pump or a specialized model for harsh environments, the 2BV series offers reliable, efficient, and durable solutions tailored to a wide range of industrial applications.
