Operation Conditions of Vacuum Pumps
I believe you are not unfamiliar with the vacuum pump, and have a lot of knowledge about it. Have you ever known about the operating conditions of the vacuum pump? If not, let's take a look at the following article.

Because vacuum pumps have selective pumping, sometimes one pump can not meet the requirements of pumping. It needs several pumps to be combined to complement each other in order to meet the requirements of pumping. For example, the titanium sublimation pump has a high pumping speed for hydrogen, but it can not pump helium, while the tripolar sputtering ion pump (or the bipolar asymmetric cathode sputtering ion pump) has a certain pumping speed for argon. If the two pumps are combined, the vacuum device will get a better vacuum degree.

In addition, some vacuum pumps can not work at atmospheric pressure, need pre-vacuum; some vacuum pumps outlet pressure is lower than atmospheric pressure, need the front pump, so they need to be combined to use.
