Vacuum pump

A vacuum pump is a device that removes gas molecules from a sealed volume to create a vacuum, or a space with significantly reduced pressure compared to the ambient atmospheric pressure. It works by extracting air and other gases from a designated area, thus lowering the pressure within that area. **Types of Vacuum Pumps:** 1. **Positive Displacement Pumps**: These pumps create a vacuum by trapping a volume of gas and then expelling it from the system.
