Regardless of the technology, the essential functioning principle of an industrial vacuum pump stays the same. Air molecules (and other gasses) are removed from the vacuum chamber using vacuum pumps (or the outlet side if a higher vacuum pump is connected in series). The removal of extra molecules gets progressively difficult when the pressure in the chamber is lowered.

As a result, an industrial vacuum system must be capable of operating across a significant percentage of a very wide pressure range, often ranging from 1 to 10-6 Torr / 1.3 to 13.3 mBar of pressure. This is extended to 10-9 Torr or below in research and scientific applications. In a normal vacuum system, multiple types of pumps are employed to do this, each covering a section of the pressure range and working in series at times.

How to Choose a Vacuum Pump?

Several factors must be addressed while choosing a vacuum pump. To begin with, your choice should be personalized to your intended purpose, enabling you to choose the technology, lubrication, chemical resistance, vacuum level, and required flow rate.

When choosing a vacuum pump, the quality and goal vacuum level should be considered the most significant elements. The three types of vacuum are a rough or low vacuum, a high vacuum, and an ultrahigh vacuum. The scarcity of the number of molecules obtained, which is defined by residual gas pressure, is the difference between the three. As the pressure falls, the number of molecules per cm3 decreases. As a result, vacuum quality increases.
