Liquid Ring Vacuum Pumps: A Step-by-Step Guide

Introduction

Liquid ring vacuum pumps are a type of positive displacement pump that uses a rotating impeller to create a vacuum. They are used in a variety of applications, including chemical processing, pharmaceutical manufacturing, and food processing.

How Do Liquid Ring Vacuum Pumps Work?

Liquid ring vacuum pumps work by using a rotating impeller to create a vacuum. The impeller is mounted eccentrically in a housing that is partially filled with operating fluid. As the impeller rotates, it creates a centrifugal force that causes the operating fluid to form a ring around the impeller. The gas to be evacuated is trapped between the liquid ring and the impeller.

As the impeller continues to rotate, the gas is compressed and expelled from the pump. The operating fluid is then returned to the pump housing, where it is used to create the vacuum again.
