A pump is a mechanical device used to move gases, liquids, or slurries. A pump moves liquids or gases from a lower pressure to a higher pressure and is responsible for this difference in pressure.
Pumps work by using mechanical forces to push the material, either by physically lifting, or by the force of compression.
Positive displacement pump
This type of pump forces the fluid from one chamber to another by reducing the volume of the first chamber while increasing the volume of the second. Such a pump produces a constant flow regardless of intake pressure or outlet pressure, unless the intake pressure drops below a certain limit, causing cavitation, or the outlet pressure exceeds the capacity of the pump, causing pump failure. These pumps often have a relief valve to prevent the latter problem. The heart of animals is a natural example of this type of pump.
Dynamic pump
The dynamic pump causes the fluid to move from inlet to outlet under its own momentum. This type tends not to need a relief valve, because as the outlet pressure rises the pump simply becomes less efficient. Fluid motion can be rotary, as in centrifugal pumps, or linear, as in reciprocating dynamic pumps.
