Abstract
A multi-throw reciprocating pump is provided. The pump provides active stroke control. Fluid flow is controlled by canceling out at least a portion of a discharge stroke of one plunger with a suction stroke of another plunger. Controlling the degree to which the discharge stroke is cancelled out is used to control the actual volume of fluid being pumped.
