Below is a list of Vacuum Pumps manufacturers from Hingham, Massachusetts. Vacuum pumps are machines that create a vacuum by removing gasses from a sealed space. A perfect vacuum is a space in which there is no matter. No naturally-occurring perfect vacuums exist, and it is impossible to create one. Industrial vacuum pumps, or vac pumps as they are often called, can be used to create partial vacuums of varying intensities; high vacuum pumps can evacuate enclosures to very low pressure levels, and small vacuum pumps create less intense vacuums.
