  • Reciprocating Pumps - an overview | ScienceDirect

    Reciprocating pumps use a piston moving back and forth in a cylinder (see Fig. 23.16).Two check valves for the input and output at one end of the cylinder allow one-way flow; this gives a pulsed output. Because rotational motions of engines are not easily converted to reciprocating motions, this type of pulp is seldom used on mobile equipment.
