Diffusion pumps are essential tools in various industrial applications, especially those requiring high and ultra-high vacuum levels.
What are the 8 Important Characteristics of a Diffusion Pump?
1. High Pumping Speed
Diffusion pumps offer a high pumping speed for all gases.
This makes them ideal for high and ultra-high vacuum applications.
They can achieve a pumping speed ranging from 10^-2 to 10^-10 torr.
2. No Moving Parts
Diffusion pumps are durable and reliable because they have no moving parts.
This feature eliminates the need for maintenance and reduces the risk of mechanical failure.
3. Simple Operational Principle
The operation of a diffusion pump is straightforward.
It relies on two main elements: diffusion pump oil and a heater.
The heater heats the oil to its boiling temperature, and the rising oil vapor is compressed in a vertically tapered stack with jet openings.
The angled jets create an umbrella of vapor that captures air molecules.
4. Automatic Vacuum Pumpdown
The operation of a diffusion pump is automatic and interlocked.
A holding pump is used to maintain a low pressure on the diffusion pump foreline at all times.
This prevents backstreaming of pump oils into the chamber.
5. Compatibility with Various Applications
Diffusion pumps are widely used in industrial applications such as electron-beam microscopy, vacuum deposition, coatings, and vacuum furnaces.
They are versatile and can handle a range of processes.
6. High Vacuum Capability
Diffusion pumps can achieve high vacuum levels below 10^-10 torr.
This makes them suitable for applications requiring extremely low pressures.
7. Cost-Effective
Diffusion pumps offer a low cost per unit pumping speed compared to other types of pumps used in the same vacuum range.
This makes them an attractive option for industrial applications.
8. Fluid Entrainment Pump
Diffusion pumps operate as fluid entrainment pumps rather than gas displacement pumps.
They capture air molecules using the vapor of a boiling fluid, which is then moved to another location and cooled to release the trapped air molecules.
