High-Speed Roots Vacuum Pump from China Suppliers and Factory - Efficient Vacuum Solution
High Strength
The entire series is equipped with QT500 high-strength ductile iron rotor, with a tensile strength of 500 MPa and an elongation rate of 15%.
Multi-seal design
The composite sealing structure technology completely solves the emulsification and leakage problems of vacuum pump oil, making it more stable and reliable.
High Precision
The accessories are precisely manufactured by imported processing centers, with strict control of the gaps between rotors and between rotors and the pump body, ensuring stable operation when the gap is less than 0.05mm.
Patented Products
Independently produced and manufactured, it has over 40 vacuum-related patents, has been rated as a national high-tech enterprise and a science and technology enterprise, and has passed ISO9001 quality management system certification.
High-Efficiency Cooling
The spiral jacket cooling method ensures excellent heat exchange efficiency, fully guaranteeing the low-temperature lubrication performance of the lubricating oil, thereby extending the service life of gears, bearings and mechanical seals.
Precision Bearings
High-strength, high lateral force precision bearings from fully imported (SKF/NSK) are selected and lubricated by splash lubrication, which can greatly extend the pump's service life.
