Abstract
A pump system includes a pump unit an assembly frame that receives first and second pumps. A first and second pedal respectively couples to a first and second pump actuating portion. A rocker arrangement has a rocker that pivotally couples the first and second pedals, so a pushing movement of the first pedal in one direction causes a pulling movement of the second pedal in an opposite direction, and vice versa. The first and second pedals respond to a pushing force, respectively move the first and second pump actuating portions for pumping a fluid from the first and second pumps, and correspondingly move the first and second pump actuating portions for drawing the fluid to be pumped into the first and second pumps.
