An Introduction to Vacuum Pumps

An Introduction to Vacuum Pumps

Jan 13, 2016 · The screw pump (Fig. 9) utilizes two rotating screws, one left-handed and one right-handed, that mesh without touching. The rotation transfers the gas from one end to the other. The screws are designed so the space between them becomes reduced as the gas passes along, and it becomes compressed, causing a reduced pressure at the entrance end.
