pump

v. draw out or move with a pump; inflate, fill with gas

n. machine used to move liquids by suction; one instance of moving liquid by suction; low cut shoe

A pump is a device used to move  liquids or slurries. A pump moves liquids 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.
