The first and most crucial thing to know and remember is to determine the amount of pressure you want from your vacuum pump. Selecting the right pressure is absolutely important for vacuum pumps; otherwise, they won’t work properly.
Here are some vacuum pumps based on their pressure that you need to remember in order to make the right choice:
- Filtration Vacuum Pumps
These vacuum pumps are usually used in laborites, and they have very specific purposes for which they should be used. Generally, these vacuum pumps operate under low pressure.
- Rough Vacuum Pumps
These vacuum pumps usually operate under less than 10–3 Torr. They are used both for laboratory and industrial purposes.
- High-Pressure Vacuum Pumps
These vacuum pumps usually operate above 10–3 Torr. They are also used both for laboratory and industrial purposes.
- Dry Pumps
These are non-lubricated pumps that require little maintenance and generate little waste material. Examples include:
Diaphragm
Piston pumps
Turbomolecular pumps
- Water-Based Pumps
These pumps use water as a lubricant and require very little maintenance. What makes them really good is that they are corrosion resistant.
The problem is that they are not good for water vapor-sensitive systems. Apart from that, disposing of the contaminated water is an additional problem, which can at times be very annoying and hectic.
- Oil-Based Pumps
These are high-speed pumps that use oil as a lubricant. These should be used preferably only for professional purposes because they require daily oil changes and regular maintenance.
That said, let’s now walk through the ways in which you can keep your vacuum pump working for years to come.
- Determine the Free Air Capacity
Your vacuum pump will work better if it has a larger capacity for free air. The larger capacity for free air your vacuum pump has, the faster it will evacuate the chamber.
- Lubrication
Decide whether you want a vacuum pump that is lubricated or not. Generally, lubricated pumps work faster and more efficiently. Also, lubricated vacuum pumps offer lower noise and higher vacuum levels.
Their major drawback is that they require more maintenance.
- Flow Rate
The time it takes for the vacuum pump to drain is known as the flow rate. Check out both the pumping speed and the mass flow rate of the vacuum pump and make sure they fit your needs and purposes. Preferably, you should use high flow rate vacuum pumps.
Conclusion
Choosing the right vacuum pump can be difficult and complicated because vacuum pumps aren’t so easy to understand. That’s why you should rely on trustable companies like LaDAB.
