Abstract
A low profile positive displacement pump system is disclosed. The pump system includes a gasoline powered engine with a vertically disposed crank shaft. The system also includes a piston pump with at least one horizontally disposed piston, and a pump shaft assembly which mounts onto the crank shaft. A base includes a cavity configured for retaining the pump. The engine mounts directly onto the base, and fixes the orientation of the pump shaft assembly with respect to a driven end of each piston. The pump shaft assembly includes at least one eccentric camming surface for contacting a driven end of the piston and for causing each piston to complete one stroke per revolution of shaft rotation. The base comprises a main body including an upper surface, wherein the upper surface is suitable for mounting directly to a mounting flange of the gasoline powered engine.
