Once powered, both pump heads move synchronously in a reciprocating motion, demonstrating the working movement of oilfield machinery.\u003cbr\u003e.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.\u003cbr\u003e.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.\u003cbr\u003e.Finished \u0026amp; 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.\u003cbr\u003e.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.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003e.Material: Brass + Copper + Nickel Silver\u003cbr\u003e.Product Weight: 600g\u003cbr\u003e.Package Weight: 800g\u003cbr\u003e.Product Dimensions: 8.3 x 8.3 x 12cm\u003cbr\u003e.Package Dimensions: 16 x 16 x 12.5cm\u003cbr\u003e.Packaging: Graphic Carton\u003cbr\u003e.Age: 16+\u003c\/span\u003e\u003c\/p\u003e","brand":"Moyustore","offers":[{"title":"Default Title","offer_id":54630637306069,"sku":"3742029","price":493.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0070\/7087\/5746\/files\/moyustore-dynamic-3d-metal-oil-pumping-unit-model-vintage-industrial-mechanical-display_8.jpg?v=1787735317","url":"https:\/\/www.moyustore.com\/products\/dynamic-3d-metal-oil-pumping-unit-model-vintage-industrial-mechanical-display","provider":"Moyustore","version":"1.0","type":"link"}
