Pumping Unit Engine Kit That Works 3D Metal Oilfield Working Equipment with Light A fidelity mechanical model that recreates the classic pumpjack, presented as a 3D metal kit with integrated lighting. Designed to demonstrate core principles of oilfield pumping machinery while serving as a collectible desktop model and hands on educational tool. Key benefits Teaches mechanical principles: clearly shows transmission and reciprocating motion found in industrial pumpjacks, making it useful for education and demonstrations. Durable metal construction: precision CNC cast metal parts and aluminum alloy oxidized finish provide a realistic look and long lasting durability suitable for display and repeated use. Visible, working mechanism: moving parts and exposed transmission let viewers follow the motion step by step, improving understanding of the machine logic. Enhanced display with lighting: built in lighting highlights motion and details for presentations or desktop display. Kit format for hands on learning: delivered as a kit to assemble, encouraging practical learning about mechanical assembly and operation. Features Construction: metal components manufactured with precision casting and CNC machining, finished with aluminum alloy oxidized color and fine machine level workmanship. Mechanical presentation: classical pumpjack structure with clearly visible transmission path and moving elements that illustrate power conversion and linkage action. Function: functioning pumping unit model with moving parts and illuminated components to aid visualization. Finish and appearance: collection grade craftsmanship designed to faithfully evoke historical industrial machines. Intended use: educational demonstration, display model, and hobbyist assembly. Practical applications Classroom demonstration: use in engineering and physics classes to illustrate reciprocating motion, linkages, and basic mechanical transmission principles. Office or home display: desktop conversation piece for engineers, hobbyists, and collectors that demonstrates movement and lighting. Hands on hobby project: assembly kit for those learning metal model construction and mechanical systems, suitable for workshops or maker spaces. Who this is for Engineers, students, educators, collectors, and hobbyists who want a realistic, working metal model of a pumpjack to study mechanical motion, enhance displays, or practice hands on assembly. Note This product is supplied as a kit with metal parts and integrated lighting designed to demonstrate pumpjack operation and to serve as a display piece and educational tool.
