What is a Vacuum pump?

A vacuum pump is a device used to remove gas from a sealed chamber to create a vacuum or low-pressure environment. Vacuum pumps are essential in various fields, especially in laboratories and factories where a controlled vacuum is required. Common applications include semiconductor manufacturing, electron microscopy, medical MRI machines, chemical analysis equipment, food packaging, and leak detection.

Main types of vacuum pumps include:
・Rotary Vacuum Pumps: Use rotating parts to expel gas and are widely used across applications.
・Dry Pumps: Operate without lubricants, suitable for cleanroom and medical applications.
・Turbo Molecular Pumps: Used for high vacuum applications, particularly in semiconductors and analytical devices.
・Oil Diffusion Pumps: Use oil to achieve ultra-high vacuum, often in research or specialized industrial processes.
・Sorption Pumps: Create extreme vacuums by adsorbing gas onto a cooled surface.
Each type offers specific capabilities and is selected based on application requirements.

Application of Vacuum pump

１．Semiconductor Manufacturing Equipment: Used to maintain a vacuum environment in the production of semiconductor chips.
２．Electron Microscopes: Requires a high vacuum for detailed observation of cells and molecular structures.
３．Food Packaging Machines: Creates vacuum packaging to prevent oxidation and maintain freshness.
４．Medical MRI Machines: Part of the MRI system uses a vacuum to improve image accuracy.
５．Freeze Dryers: Used in the pharmaceutical and food industries to remove moisture in a vacuum, allowing for long-term preservation.
