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, an engine of some type, or wind power.
Specifications:
Pumps are commonly rated by horsepower, flow rate, outlet pressure in metres (or feet) of head, inlet suction in suction feet (or metres) of head. The head can be simplified as the number of feet or metres the pump can raise or lower a column of water at atmospheric pressure.
From an initial design point of view, engineers often use a quantity termed the specific speed to identify the most suitable pump type for a particular combination of flow rate and head.
