The function of high-speed turbine vacuum pump
High speed turbo vacuum pump is a power type dry vacuum pump based on high-speed rotation of centrifugal impeller to achieve gas momentum transfer. Its core function is to quickly establish and maintain a medium high vacuum environment (typical range: 10 ⁻ ² to 10 ⁻ Pa) through single-stage efficient compression without the need for working fluid or lubricating oil. It is widely used in industrial and scientific research scenarios that require strict cleanliness, energy efficiency, and stability.
Core functions and technological advantages
Efficient pumping and high vacuum capacity
By adopting a supersonic three-way flow impeller and a high-speed gearbox design, a single-stage can achieve a maximum vacuum degree of -75 kPa to -78 kPa, breaking through the limitations of traditional two-stage series technology and significantly improving the pumping speed and energy efficiency ratio.
Energy conservation and environmental protection
Compared to traditional water ring pumps, it can save 30% -70% energy, with a water saving rate close to 100%. There is no working fluid circulation, completely eliminating oil pollution, corrosion, and wastewater discharge problems, which is in line with the trend of green manufacturing.
Low noise and high stability
No mechanical friction, magnetic levitation bearings (some models) or precision dynamic balancing design, resulting in operating noise below 80 dB and minimal vibration, suitable for precision instrument surroundings and clean room environments.
Oil free dry operation
The entire process is oil-free and sealed to prevent oil vapor from diffusing back, ensuring the cleanliness of the vacuum chamber. It is an ideal choice for industries such as semiconductors and biomedicine that have zero tolerance for pollution.
Intelligent regulation and adaptability to wide working conditions
Equipped with a PLC intelligent control system, it supports online adjustment of vacuum degree, anti surge protection, and remote monitoring, and can adapt to changing process requirements without the need for multi-level series connection, improving the flexibility of the production line.

Current technological challenges
Extreme high vacuum (<10 ⁻⁷ Pa) still needs to be combined with molecular pumps, and single-stage turbine pumps are difficult to cover.
High rotor linear velocity requires extremely high material and manufacturing accuracy, and domestically produced core components such as magnetic levitation bearings and high-speed impellers still rely on imports.
The initial procurement cost is higher than traditional pumps, but the total cost of ownership (TCO) is significantly lower.
