At the intersection of precision manufacturing and cutting-edge technology, oil-free scroll technology… Vacuum pump With core principles akin to geometric art, it has redefined the industry standard for cleaning vacuums.
I. Core Principle: A Vacuum Revolution Driven by Geometric Beauty
Through the relative motion of two precisely meshing involute scroll disks, a crescent‑shaped sealed cavity is dynamically displaced. As the moving disk performs an eccentric rotary motion around the fixed disk, gas is drawn in from the outer periphery and progressively compressed toward the center, ultimately being discharged through the central exhaust port. This non‑contact design eliminates frictional losses, while the 0.02 mm machining accuracy of the scroll disks ensures that vacuum level fluctuations remain within 5% over a ten‑year period.
II. Three Irreplaceable Application Scenarios
Life sciences: Prevent oil vapor contamination of the incubator environment to ensure the purity of stem cell research.
Analytical instrument integration: Provides a stable vacuum environment for the mass spectrometer, enhancing detection accuracy by three orders of magnitude.
New Energy Manufacturing: Achieving a vacuum environment with zero residual hydrocarbon emissions in the lithium‑ion battery separator coating process.
III. Industrial Upgrading Behind Technological Barriers
The scroll wheel, crafted from a specialized polyether ether ketone (PEEK) material, maintains deformation control within 0.005 mm even at high temperatures of 180°C. Magnetic‑levitation bearing technology reduces mechanical losses to one‑twentieth of those in conventional pumps, enabling 20,000 hours of maintenance‑free operation. These advancements have boosted the market share of domestically produced equipment in front‑end semiconductor processes from 5% to 34%.
When the “dual carbon” goals converge with the upgrading of precision manufacturing, oil-free scroll vacuum pumps are rewriting the rules of industry. They are not merely vacuum generators in physical space; they also serve as a metaphor for China’s intelligent manufacturing as it ascends to the high end—leveraging a cleaner energy mix to underpin a more precise industrial future.

Applications of Intelligent Scroll Vacuum Pump Technology: PLC Touch‑Control Operation, Remote Status Monitoring, Energy Consumption Data Collection, and Automatic Fault Alerts
In the production processes of specialized industries such as chemicals, pharmaceuticals, biopharmaceuticals, and fine chemicals, complex operating conditions often arise—characterized by corrosive gases, acidic or alkaline vapors, and the evaporation of trace organic solvents. Conventional vacuum pumps are highly susceptible to corrosion and aging, with cavities prone to rusting and components suffering damage. This not only shortens equipment life but also gives rise to potential hazards such as unstable vacuum levels, medium leakage, and production interruptions. The corrosion‑resistant scroll vacuum pump is specifically engineered for harsh, corrosive environments, featuring a dry, oil‑free design and corrosion‑enhanced materials, making it a high‑performance dry vacuum solution tailored for the chemical and pharmaceutical sectors.
How to Choose a Rotary Vane Vacuum Pump? A Comprehensive Analysis of Key Parameters and Buying Tips
In industries such as laboratory research, healthcare, packaging, chemical processing, semiconductors, and industrial automation, scroll vacuum pumps have become the mainstream oil-free vacuum equipment. Yet many buyers focus solely on price and power while overlooking critical specifications; as a result, the units they purchase often deliver insufficient ultimate vacuum or inadequate pumping speed, generate excessive noise, overheat easily, or prove unreliable—falling short of the performance required for production and experimental applications.
When purchasing vacuum equipment, many companies and laboratories often face a tough decision: should they choose a scroll vacuum pump or a screw vacuum pump? Both are oil-free, dry‑type pumps that can deliver clean vacuums, but they differ significantly in design, ultimate vacuum level, pumping speed, price, and application scenarios. Choosing the wrong one not only wastes your budget but may also fail to meet your process requirements.
The company primarily engages in the research, development, manufacturing, and sales of oil-free scroll vacuum pumps. It boasts a nationally leading R&D and operations management team in the field of oil-free scroll compression technology, as well as some of the world’s most precise machining and three‑coordinate measuring equipment.
