Pump Basics
Pumps are used to add energy to fluids (gases, liquids, or slurries) to produce flow or increase pressure. This course discusses the construction and operation of the two most basic types of pumps: positive displacement and centrifugal. In addition to how pumps function, it is also covers some of the common terms which are used to describe pump performance.

Sample Video Transcript
One of the most common types of positive displacement pumps is the gear pump. A gear pump uses the pockets created by a pair of turning gears to transfer and pump fluid. At the inlet side of the pump, fluid flows into the area where turning gears separate from each other. As the gears rotate and meet the casing of the pump, fluid is trapped in the space between the teeth and the case. Fluid travels around the interior of the casing. Because the meshing of the gears creates a seal and prevents fluid from returning to the inlet, it is forced under pressure through the outlet port.
