High-Performance Oil Diffusion Vacuum Pumps: Advanced Vacuum Solutions for Industry and Research

All Categories

oil diffusion vacuum pump

The oil diffusion vacuum pump represents a sophisticated high-vacuum technology that operates on the principle of vapor jet diffusion. This innovative device uses specialized oil heated to its boiling point, creating vapor that captures and directs gas molecules from the chamber being evacuated. As the oil vapor condenses on the water-cooled walls, it carries trapped gas molecules downward, effectively reducing pressure in the system. The pump achieves exceptional vacuum levels, typically reaching pressures as low as 10^-7 torr, making it ideal for demanding industrial and scientific applications. The system comprises multiple stages of jets, each contributing to the progressive compression of gases, while the cooled walls ensure efficient vapor condensation and oil recycling. Modern oil diffusion pumps incorporate advanced features such as precisely engineered jet assemblies, optimized heating elements, and efficient cooling systems that maximize performance while minimizing energy consumption. These pumps are particularly valuable in semiconductor manufacturing, thin-film deposition, electron microscopy, and various other high-tech processes requiring ultra-high vacuum conditions.
