Pump Wikipedia
A pump is a device that moves fluids (liquids or gases), or sometimes slurries, by mechanical can be classified into three major groups according to the method they use to move the fluid: direct lift, displacement, and gravity pumps. Pumps operate by some mechanism (typically reciprocating or rotary), and consume energy to perform mechanical work moving the fluid.
