Abstract
Abstract An improved pumping apparatus featuring a rotating frame having lever-actuated pump assemblies located thereabout. The levers are weighted at their distal ends and pivot about fixed fulcrum points as the frame rotates. The proximal ends of the levers are spur gears that engage and reciprocate a pump rod of each pump assembly via a rack gear portion of the pump rod. Pistons disposed in pump cylinders are connected to ends of the pump rods, and these pistons apply pumping force to a fluid, the fluid being communicated to the pump cylinders via conduit means that communicate with external fluid sources through an annulus pipe, and through an interdisposed inner pipe, these pipes also serving as the axle support for the frame.
