KAIEN Launches New Generation of Dry Screw Vacuum Pumps, Setting New Standards for Clean Industr

Jinan, China – Shandong Kaien Vacuum Technology Co., Ltd., a leading innovator in vacuum solutions, has announced the full-scale production and global availability of its advanced line of dry screw vacuum pumps. These pumps are poised to revolutionize processes in industries demanding high vacuum, clean environments, and sustainable operation. To explain the significance of this technology and Kaien's approach, we sat down with the company's Chief Technology Officer for a brief Q&A.

Q: For those unfamiliar, what is a screw vacuum pump, and what makes it special?

A: "At its core, a screw vacuum pump is a highly efficient, positive displacement pump. It uses two meticulously engineered screw rotors that rotate in sync within a sealed chamber. As they turn, they create moving sealed chambers that trap, transport, and expel gases from the inlet to the outlet, generating a vacuum. The 'dry' aspect is key: our pumps operate without any oil or lubricants in the pumping chamber. This eliminates contamination, making them ideal for sensitive processes."

Q: Kaien emphasizes the 'highest standard' in manufacturing. What does this entail for your screw pumps?

A: "Precision is everything. The exceptional performance—like achieving a high vacuum limit of ≤1Pa—relies on maintaining microscopic, consistent gaps between the rotating screws and the chamber walls. Any deformation or imperfection is unacceptable. Therefore, we use specially treated, dimensionally stable materials for critical components. Our rotors undergo precision machining and dynamic balancing. We pair them with high-grade bearings like SKF/NSK and precision grade-5 ground gears. This ensures smooth, vibration-free, reliable, and long-lasting operation right out of the box."

Q: What are the primary advantages you offer to customers with this technology?

A: "We deliver a powerful combination of performance and cleanliness:

• Truly Clean Vacuum: No oil means no risk of contaminating the process medium. This is critical for pharmaceuticals, food processing, or semiconductor manufacturing, and it allows for direct recovery of valuable extracted solvents or gases.
• High Performance & Versatility: Our pumps provide strong, stable pumping speeds even in high vacuum ranges. They can handle challenging media, including condensable vapors (like water or solvents) and gases with minor dust. With optional corrosion-resistant coatings on wetted parts, they are also suitable for certain aggressive gases.
• Operational Efficiency & Low TCO: Features like our variable-pitch screw design enhance energy efficiency and reduce noise. The robust design and high-quality components minimize downtime and maintenance costs, offering a lower total cost of ownership despite the sophisticated engineering."

Q: Are there any limitations to where these pumps can be applied?

A: "As with any technology, there are optimal use cases. Our dry screw pumps are not recommended for pumping explosive gases or gases with dangerously high oxygen content due to safety considerations. For these specific applications, alternative solutions should be explored."

Q: Can you describe the range of products Kaien offers?

A: "We provide a comprehensive portfolio to meet diverse needs. Our series includes both air-cooled models, perfect for simpler integration and operations where water is limited, and water-cooled models for higher-power applications requiring efficient heat dissipation. We offer models with pumping speeds ranging from compact 5.5 m³/h units up to large industrial 1800 m³/h systems. Furthermore, our pumps are designed to work as standalone units or be easily integrated into complex pumping systems."

Q: Finally, what industries is Kaien targeting with this technology?

A: "Our pumps are engineered for modern industry challenges. Key application areas include Oil & Gas Recovery, Solvent Recovery, Vacuum Coating, Biopharmaceuticals, Food Processing, Electronics & Photovoltaics, and Vacuum Metallurgy. Anywhere there's a need for reliable, clean, and efficient vacuum, Kaien's screw vacuum pump is an ideal solution."
