Vacuum pumps

2.1.2. Dry pumps. Membrane pumps; Roots pumps. The rotary lobe pump (Roots) is excellent for moving large quantities of gas at higher pressure than possible with the rotary oil or piston pumps. Roots pumps are in use in molecular beam experiment and IC fabrication lines that need high pumping speed at 0.1 to 10 Tr.

Vacuum Pumps - Visual Encyclopedia of Chemical Engineering

Depending upon the pressure range, vacuum pumps can be separated into two general categories: rough-medium vacuum, ranging from 760 to 10 -3 torr (1 to 1.3 x 10 -6 atm) and high-ultrahigh vacuum, ranging from .... Common backing pumps are oil-sealed rotary piston pumps, rotary vane pumps, or liquid ring pumps.

molecules certainly move, and with high velocity at that, there is no net gas flow and no pressure gradients in such a system. When gas does flow, however, it is ..... than oxygen, water, or nitrogen and several hundred times faster than argon. Unlike cryopumping action, the gases are permanently removed. These pumps are...
