A pump is a device that moves fluids -LRB- liquids or gases -RRB- , or sometimes slurries , by mechanical action .. slurries. Slurry. Pumps 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 -LRB- typically reciprocating or rotary -RRB- , and consume energy to perform mechanical work by moving the fluid .. reciprocating. Reciprocating motion. rotary. Rotation. energy. energy. mechanical work. mechanical work. Pumps operate via many energy sources , including manual operation , electricity , engines , or wind power , come in many sizes , from microscopic for use in medical applications to large industrial pumps .. energy. energy. electricity. electricity. engines. engines. wind power. wind power. Mechanical pumps serve in a wide range of applications such as pumping water from wells , aquarium filtering , pond filtering and aeration , in the car industry for water-cooling and fuel injection , in the energy industry for pumping oil and natural gas or for operating cooling towers .. gas. gas. energy. energy. pumping water from wells.

In the medical industry , pumps are used for biochemical processes in developing and manufacturing medicine , and as artificial replacements for body parts , in particular the artificial heart and penile prosthesis .. medical industry. medical industry. artificial heart. artificial heart. penile prosthesis. penile prosthesis. Single stage pump -- When in a casing only one impeller is revolving then it is called single stage pump .. Double / multi-stage pump -- When in a casing two or more than two impellers are revolving then it is called double / multi-stage pump .. In biology , many different types of chemical and bio-mechanical pumps have evolved , and biomimicry is sometimes used in developing new types of mechanical pumps .. evolved.
