The Guangde facility is equipped for a vertically integrated workflow that spans machining, motor production, assembly, testing, spraying, grinding, and welding. The company also states that it maintains a microcomputer-controlled product performance testing system, indicating an internal quality-control capability intended to support product validation and consistency.
Beyond equipment manufacturing, the company describes its offering as including vacuum-system design, installation, and vacuum piping fabrication for whole-factory projects. This indicates that the company participates not only in component supply but also in project-level engineering for industrial users.
Products and Technologies
The company’s principal products include:
- Water ring vacuum pumps
- Roots vacuum pumps
- Rotary vane vacuum pumps
- Vacuum units
- Centrifugal water pumps
