Pump – a device used to move gases, liquids or slurries.
- A pump moves liquids or gases from lower pressure to higher pressure, and overcomes this difference in pressure by adding energy to the system (such as a water system).
- A gas pump is generally called a compressor, except in very low pressure-rise applications, such as in heating, ventilating, and air-conditioning, where the operative equipment consists of fans or blowers.
- Pumps work by using mechanical forces to push the material, either by physically lifting, or by the force of compression.
- reciprocating-type pumps use a piston and cylinder arrangement with suction and discharge valves integrated into the pump.
