A reciprocating pump including a sleeve comprising a first flow path element and a plunger receivable in the sleeve is provided. The plunger includes a fluid contact face and second flow path element in fluid communication with the fluid contact face. The sleeve and the fluid contact face define a compression chamber comprising an inlet and an outlet. The sleeve and the plunger are moveable relative to one another for adjusting overlap between the first flow path element and the second flow path element for diverting flow of fluid from the compression chamber and out of the second flow path element during a discharge stroke to control flow of fluid pumped out of the outlet.
