A reciprocating pump configured to operate the pump by reciprocating movement of the reciprocating rod, wherein the motor is a servo motor equipped with an encoder or a pulse transmitter, and the servo motor The rotational operation of the rotational shaft of the motor is feedback-controlled by the control unit, and the motion converting means is attached to the rotational shaft of the servo motor, and a screw shaft and a plurality of threaded portions are dually formed on the reciprocating rod. A reciprocating pump comprising a ball screw mechanism screwed together through balls.
