Greentech International (Zhangqiu) Co., Ltd is a leading supplier of vacuum pumps, offering high-quality and reliable solutions for various industrial applications. The 2BV series water ring vacuum pumps are designed for efficient pumping of gases and steam, with suction pressures reaching up to 33 mbar (ABS), equivalent to a 97% vacuum level. When using transformer oil as the operating fluid, these pumps can achieve even higher performance, reaching 6.7 mbar (ABS), or 99% vacuum, making them a perfect replacement for traditional reciprocating vacuum pumps.
These pumps are ideal for environments where continuous operation near the maximum vacuum is required. To prevent cavitation and protect the pump, a cavitation protection pipe is recommended when working under such conditions. In compressor mode, the maximum discharge pressure can reach 0.26 MPa (ABS), and the motor power increases accordingly. Therefore, it’s essential to provide the discharge pressure data to select the appropriate motor size.
The 2BV2-Ex and 2BV6 series models are specifically designed for use in explosive or flammable environments, featuring explosion-proof motors and safe operation. These models share similar technical specifications with the standard 2BV2 and 2BV5 series products. Additionally, stainless steel versions of the 2BV series are available for applications requiring high corrosion resistance and cleanliness.
All components that come into contact with the liquid—such as the pump casing, cover, port plate, and impeller—are made from different grades of stainless steel, including SUS304, SUS316, and SUS316L. The shaft material is either 2Cr13 or 0Cr18Ni12Mo2Ti, while mechanical seals are sourced from John Crane, with options for FPM or PTFE materials.
Key features of the 2BV series include:
- A compact design that saves space and simplifies installation.
- Standard use of John Crane mechanical seals for long-lasting performance.
- A built-in cavitation protection port that helps reduce noise and protect the pump during prolonged operation near the maximum vacuum.
- An aluminum bronze impeller that offers high strength and wear resistance, enhancing the pump's durability.
- A unique discharge port design that prevents overpressure and ensures optimal efficiency.
- Motors from the Y2 series with IP54 or IP55 protection ratings and F-class insulation.
- High-quality bearings from reputable brands like NTN or NSK for reliable operation.

Medical Repair Injection Mould
Polyetheretherketone (PEEK) is a high-performance engineering plastic with excellent biocompatibility, biostability, high strength, rigidity and wear resistance. It also has high temperature tolerance, chemical stability and X-ray transparency, which makes PEEK widely used in the medical field, especially in orthopedic surgery.
Interface screw is a screw used to fix the interface connection between implanted devices and human tissues, usually used to provide stable implant positioning and support. In orthopedic surgery, interface screws are often used to fix bone parts after fractures or bone cutting, as well as soft tissue reconstruction and repair.
Peek interface screw die refers to the PEEK Suture Anchor mould to manufacture polyetheretherketone interface screws. The design of this plastic molds requires precise consideration of the shape, size, thread and other details of the screw to ensure that the produced screws can meet the strict requirements of medical implants.
The manufacture of injection mould usually includes multiple links such as design, processing, assembly and debugging. In the design stage, it is necessary to accurately calculate and design according to the specific requirements of the screw (such as size, shape, thread type, etc.); in the processing stage, high-precision machine tools and tools are needed for processing to ensure the accuracy and surface quality of the mold; finally, in the assembly and debugging stage, the plastic injection mold needs to be assembled and tested to ensure that it can normally produce qualified screws.
Due to the special properties of PEEK materials (such as high temperature tolerance, chemical stability, etc.), the manufacture of peek interface screw die needs to meet a series of technical requirements, such as high temperature resistance, corrosion resistance, high precision, etc. In addition, the material and manufacturing process of plastic molds also need to be strictly selected and controlled to ensure that they can meet the quality requirements of medical implants.
With the continuous advancement of medical technology and the continuous improvement of people's health needs, the requirements for implants in orthopedic surgery are also getting higher and higher. As a high-performance implant fixation device, polyetheretherketone interface screws play an increasingly important role in orthopedic surgery. Therefore, the manufacture and application of peek interface screw die also have broad market prospects and development space.
