Due to the fact that the performance of various vacuum pumps not only meets the common requirements for vacuuming containers, but also has differences. Therefore, it is very important to clarify the work tasks that the pump undertakes in the vacuum system when selecting.

1. Be the main pump in the system

The so-called main pump is a vacuum pump that directly evacuates the vacuum system container to obtain the required vacuum degree to meet the process requirements.

2. Front stage pump

Pre stage pump refers to a vacuum pump used to maintain the pre stage pressure of another pump below its maximum allowable pre stage pressure.

3. Ultra high vacuum pump

Ultra high vacuum pump refers to a vacuum pump that operates in the ultra-high vacuum range.

4. Rough pumping pump

Coarse vacuum pump refers to a vacuum pump that reduces the pressure of a vacuum system from atmospheric pressure until another pumping system can start working.

5. Boosting pump

A booster pump usually refers to a vacuum pump that operates between a low vacuum pump and a high vacuum pump, used to increase the pumping volume of the pumping system in the intermediate pressure range or reduce the pumping rate requirements of the preceding pump.

6. Maintain pump

Maintaining a pump refers to the situation where the vacuum system has very little pumping and cannot effectively utilize the main front-end pump. For this purpose, an auxiliary front-end pump with a lower pumping speed is equipped in the vacuum system to maintain the normal operation of the main pump or to maintain the low-pressure vacuum pump required for the evacuated container.

7. Coarse vacuum pump or low vacuum pump

Coarse and low vacuum pumps refer to vacuum pumps that operate within a low or coarse vacuum pressure range after reducing the pressure of the container being pumped from the atmosphere.

8. High vacuum pump

A high vacuum pump refers to a vacuum pump that operates in a high vacuum range.
