Diffusion pumps are commonly used in industrial applications that require high vacuum levels. However, they come with several disadvantages that you should be aware of before choosing one for your specific application.
What are the 5 Key Disadvantages of a Diffusion Pump?
1. Fire and Explosion Risks
Diffusion pumps can generate fires or explosions if exposed to high concentrations of oxidizing agents, such as air. This is due to the fact that some working fluids used in diffusion pumps are combustible.
2. Contamination of the Vacuum Chamber
The working fluid used in diffusion pumps can contaminate the vacuum chamber and the devices it contains. This can affect the performance and reliability of the equipment.
3. Safety Risks
Flooding of the pump can result in solvent squirting out of the back of the pump, posing a fire safety hazard or health risks if corrosive or carcinogenic solvents are used.
4. Solvent Loss
In processes like rotary evaporation, where solvent recovery is important, diffusion pumps can lead to solvent loss. If the solvent doesn't have time to condense into the collection flask, the solvent recovery rate decreases. Once the solvent enters the pump, it cannot be recovered.
5. Inefficient Process
Using a diffusion pump that is not powerful enough for the application can result in a slow and inefficient process. It is important to select a pump with the appropriate flow rate for optimal performance.
