Vacuum Pumps, Blowers, and Ejectors

Liquid-ring vacuum pumps, centrifugal blowers, and steam ejectors are three devices that are commonly used to produce vacuum. This module explains how liquid-ring vacuum pumps create vacuum, explains why vacuum pump seal water should be cool, and describes the operation of liquid-ring vacuum pumps, single-stage and multi-stage centrifugal blowers, and steam ejectors.
