Old Water Pump

Water Pump Your hands are pushing hard against the water pump to bring up the crystal clear and cold water. The water rushes to the surface and shimmers, as the hot rays of the sun are absorbed into its cool reflection. There is a good deal of effort involved in coercing the water through the pump, but the rhythm created is steady and the satisfaction in tasting its refreshing qualities unparalleled. A pump is a device that moves fluids (liquids or gases), or sometimes slurries, by mechanical action. 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 (typically reciprocating or rotary), and consume energy to perform mechanical work by moving the fluid. 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.
