Product Description

1. The DUO series vacuum pumps are high - performance rotary vane vacuum pumps, mainly used in low and medium vacuum applications. The detailed introduction is as follows:
- Product Features
- Wide Range of Pumping Speeds: The pumping speed ranges from 1.25 to 300 m³/h, which can meet the needs of different applications.
- High - operation Safety: An integrated hydraulic - controlled high - vacuum safety valve is equipped to ensure high - operation safety.
- Environmental Protection: The design of reducing oil mist emissions, the innovative drive concept and the optional magnetic coupling make the pump clean and environmentally friendly.
- Long Service Life: The pumping speed is not affected by the gas type, and the magnetic coupling design ensures a long service life and low maintenance.
- Compact Design: The compact structure and optimized cooling function make the pump very suitable for embedded systems, which can save space.
- Structural Design
- It is a positive - displacement pump, which consists of a housing and vanes. The vanes are installed on the rotor, and the center of the circular casing is offset from the rotor. As the rotor rotates, the vanes slide in and out of the rotor to form vane chambers for pumping.
- Optional Types
- Standard Series: Filled with mineral oil, it is suitable for a wide range of vacuum technology fields.
- Magnetic - coupled Series: It has a non - friction magnetic coupling, which can avoid the oil leakage problem of the traditional shaft seal.
- Corrosive Version: It can be used with perfluoropolyether (PFPE) working fluid. The inert working fluid enables the pump to be used in highly corrosive processes.
- Explosion - proof Version: Such as the Duo 11 ATEX model, which is certified according to the ATEX directive 2014/34/EU and is suitable for processes in explosive environments or for evacuating explosive gases and vapors.
- Technical Parameters
- Take DUO 125 M as an example, the pumping speed is 115 m³/h at 50 Hz and 135 m³/h at 60 Hz. The final pressure is 4×10³ hPa with gas ballast and 2×10³ hPa without gas ballast. The power is 4 kW at 50 Hz and 4.5 kW at 60 Hz.

2. The DUO series vacuum pumps are widely used in various fields, mainly as follows: 
- Analytical Instruments: It is often installed in analytical instruments such as mass spectrometers and electron microscopes. For example, Agilent's gas - mass spectrometers and Bruker's gas - mass spectrometers use Pfeiffer DUO series vacuum pumps to provide the required vacuum environment, ensuring the accuracy and stability of analytical results.
- Vacuum Coating: Play a key role in optical coating and other processes. In the coating equipment of Hauzer and Oerlikon, DUO series vacuum pumps are selected to quickly pump out the gas in the vacuum chamber, helping to deposit a uniform film, and improving the quality and performance of the film.
- Semiconductor Manufacturing: Although not as prominent as turbomolecular pumps in ultra - high vacuum applications, DUO series vacuum pumps can be used as fore - pumps in some processes, cooperating with other high - vacuum pumps to provide a stable vacuum environment for processes such as ion implantation and doping, and contributing to ensuring the yield and performance of chips.
- Laboratory Applications: Suitable for general laboratory and chemical laboratory applications, such as freeze - drying experiments. It can quickly create a vacuum environment, so that substances can be dried under low - temperature conditions without destroying their thermal - sensitive components, and is an important equipment in pharmaceutical research, food processing and other research fields.
- Industrial Manufacturing: Widely used in key industrial applications such as drying processes, metallurgical processes, and resin casting systems. In the drying process, it can accelerate the volatilization of water; in the metallurgical process, it can prevent metal oxidation; in the resin casting system, it can help remove bubbles and improve the quality of castings. It can also be used as a fore - pump for turbomolecular pumps or Roots pumps in accelerators or battery production to provide the required pre - vacuum.
- Aerospace: It is used in some aerospace - related equipment, such as mass spectrometers on aircraft, to provide a stable vacuum environment for the normal operation of equipment, and is of great significance for aerospace testing and research.
