Filling the pump casing and the suction pipe with the liquid before it is started is known as priming. Unless the centrifugal pump is primed, it will not start as there is no centrifugal head impressed on the liquid. Positive displacement type reciprocating or rotary pumps do not need priming because the air, if any, in the cylinder or casing is driven out by the piston or vanes.
