Pumps

Abstract

A pump is a device used to move gases, liquids or slurries . A pump moves liquids or gases from lower pressure to higher pressure, and overcomes this difference in pressure by adding energy to the system (such as a water system). A gas pump is generally called a comp ressor, except in very low pressurerise applications, such as in heating, ventilating, and air conditioning, where the operative equipment consists of fans or blowers.
