Rotodynamic pumps use motion to generate more energy in a fluid and then cause the fluid to move along a pipe. Pumps such as these generally use a motor to turn a device that will increase pressure on a fluid or will increase the flow rate of the fluid using centrifugal force.
Different pumps can be used for different places and usages, for example, there are Slurry Pump, Dredge Pump, Gravel Pump, Froth Pump, Sump Pump and so on. And they are always equipped with other Pump Parts to get a expected effect.
