Abstract
Abstract Apumping system utilizing drive means activating a top pump and a ratchet drive rotary control valve selectively switching fluid pressure to a double acting dual piston dual cylinder bottom pump. The two pumps are interconnected by dual pipes through a rotary valve and a multiplicity of check valves causing the dual pipes to alternatively function as a pressure power line or a delivery line depending on the relative position of the control valve. An alternative spool valve control may be employed in conjunction with any source of fluid pressure to activate the bottom pump.
