A portable vacuum pump is a compact and lightweight vacuum pump that can be easily carried and used in various locations. These pumps work by physically removing gas molecules from a sealed volume, creating a partial or high vacuum. Portable vacuum pumps are commonly used in applications where a fixed vacuum pump is not practical, such as field tests, laboratory experiments, and maintenance and repair work.

They can be powered by electricity, batteries, or manual operation and come in a variety of sizes and capabilities to meet the specific needs of different applications. Portable vacuum pumps are designed for ease of use and mobility, making them a valuable tool for a wide range of industries and applications.
