Dynamic 3D Metal Oil Pumping Unit Model Vintage Industrial Mechanical Display

Dynamic Double-Head Oil Pumping Unit Model, Vintage Gear-Driven Industrial Oilfield Machinery Display, 3D Metal Mechanical Model with Glass Dust Cover and Wood Base, Finished Model Features: .Dynamic Gear Transmission: Reproducing the structure of a double-head oil pump jack, this finished model features visible gears and connecting rods. Once powered, both pump heads move synchronously in a reciprocating motion, demonstrating the working movement of oilfield machinery. .Multi-Metal Construction: The main structure combines brass, copper, and nickel silver components with precision-machined gears and connecting rods. A wood base and transparent glass cover complete the industrial display, while the cover helps keep internal mechanical components protected from dust. .Desktop Industrial Display: Measuring approximately 83 × 120 mm, the compact model fits naturally on office desks, study tables, and display cabinets. The transparent cover provides a clear view of the gear linkage, making the model both a decorative piece and a mechanical demonstration display. .Finished & Ready to Operate: Arriving fully assembled, the model requires no complicated construction. The integrated switch on the base provides straightforward operation, allowing the double-head mechanism to begin moving after power connection. .Protective Display Design: The transparent glass enclosure helps reduce dust accumulation around the gears, while the wood base provides a stable platform for display. The mechanical structure can be appreciated both as a stationary industrial model and during powered operation.
