Development History of Vacuum Pumps Vacuum technology has developed alongside major advances in science, manufacturing, medicine, electronics, and other industries. From early mechanical devices used to demonstrate atmospheric pressure to today’s compact and oil-free vacuum pumps, the development of vacuum technology has been driven by the need for cleaner, quieter, more reliable, and more efficient gas removal. Today, vacuum pumps are widely used in medical suction equipment, dental suction systems, laboratory instruments, packaging machines, industrial equipment, and many other applications. In medical suction equipment in particular, the pump must provide stable vacuum performance while maintaining low noise, low vibration, cl
