3D Pumping Unit Model DIY Metal Oilfield Working Equipment Assembly Kit (Model DM601, 219 pieces) A precision metal assembly kit that reproduces a classic oilfield pumping unit at display scale. Components are CNC processed and anodized, providing a durable, collectiblequality model. The kit delivers a handson assembly experience that mirrors professional assembly line craftsmanship while revealing the mechanical principles and visible transmission of a functioning pumping unit. Key benefits Real metal construction: Aluminum alloy and stainless steel parts with CNC process precision casting and anodized finish for longlasting appearance and accurate detail. Educational and visual: The model demonstrates core machine operation and clear transmission paths, making it useful for learning mechanics, teaching, or technical demonstration. quality parts: 219 precisely polished components produced with special abrasive tools for refined surfaces and smooth movement. Engaging assembly: Stepbystep assembly offers a focused, rewarding build that enhances fine motor skills and mechanical understanding. Assembly difficulty rated 2 stars; typical assembly time about 2 hours. Functional and displayready: Once assembled and powered, the unit illustrates the working principles of a pumping mechanism while serving as a mechanical desk display or collectible. Specifications Model: DM601 Number of parts: 219 pcs Material: Aluminum alloy and stainless steel Coloring process: Anodizing Finished size: 247 x 54 x 227 mm (24.7 x 5.4 x 22.7 cm) Product weight: 636 g Package dimensions: 26.5 x 22 x 6 cm Package weight: 1252 g Packing: Plastic box with blister insert Assembly difficulty: 2 stars Assembly time: About 2 hours Power and battery: Charging voltage DC5V, battery capacity 500 mAh Package contents 1 set x Pumping Unit (219 parts, hardware, and motor assembly as required for a single working model) Practical uses and scenarios Educational demonstration: Use in classrooms or workshops to explain the principles of reciprocating pumps, linkages, and mechanical transmission. Hobby and collection: Build and display on a workbench, office desk, or shelf as a collectible engineering model. Prototype study and presentation: Include in technical presentations or passive demonstrations to show how classic pumping units operate. Notes on assembly and operation Assembly follows a stepbystep process; gather tools and follow the included instructions for results. Charging requires a DC5V power source; use an appropriate 5V adapter or power supply. The kit is designed for handson assembly and mechanical demonstration rather than industrial use. This kit combines metal craftsmanship, clear mechanical design, and an instructive build process to create a precise, workingscale model of a classic pumping unit.
