Manufacturing

　　Our company has successfully obtained certifications under the ISO 9001 Quality Management System, the ISO 14001 Environmental Management System, the EU CE marking, and the 3A Credit Rating System. We are a member of the China Pharmaceutical Equipment Industry Association and the Medical Gas Equipment Engineering Branch of the China Association for Medical Device Industry. Currently, we hold nine domestic patents for dry‑screw vacuum pumps and six design patents.

　　Our company’s VDP series variable-pitch screw vacuum pumps are designed and manufactured using German rotor profile technology, featuring a three‑section, five‑stage screw profile. They are machined on original German DMG five‑axis turn‑mill machining centers, ensuring optimized design and precision manufacturing with tolerances down to the micron level. This guarantees tight clearances during high‑speed operation, minimizing internal backflow, boosting effective pumping speed, and delivering low power consumption, minimal temperature rise, and exceptional energy efficiency. These pumps are widely employed in domestic processes such as pharmaceutical intermediates and fine chemical production.
