Industrial Dissectibles by DAC Worldwide
There is no better way to prepare a maintenance technician to work on a piece of industrial equipment than to let them take it apart, examine every component, and put it back together. That hands-on process builds the component familiarity, procedural confidence, and spatial understanding that no lecture, diagram, or cutaway display can fully replicate. The challenge is that doing this with equipment in an operating facility is expensive, risky, and logistically complicated.
DAC Worldwide's industrial dissectibles solve that problem. These are actual industrial pumps, valves, gear reducers, steam turbines, and other components that have been professionally restored and prepared specifically for repeated classroom disassembly, inspection, and reassembly training. All components and design features are retained, so learners work with the real thing, in a training environment designed for exactly this purpose.
Klein Educational supplies DAC Worldwide dissectibles to industrial maintenance programs, process technology training departments, community colleges, and workforce development centers across California, Oregon, Washington, Arizona, Nevada, Hawaii, and Alaska. We help programs find the right dissectibles for their curriculum and get them delivered.
What are DAC Worldwide dissectibles?
DAC Worldwide's dissectibles are real industrial components that have been carefully restored, cleaned, primed, and finished with high-durability urethane coatings to prepare them for repeated training use. Unlike cutaways that are permanently sectioned for viewing, dissectibles retain their full complement of components and can be completely disassembled and reassembled by learners, over and over again, providing the kind of hands-on procedural experience that builds genuine maintenance competency.
Each dissectible includes all primary components and design features of the original industrial equipment, allowing for realistic demonstration and training in the design, operation, and shop maintenance of common industrial components. The dissectibles are mounted on steel baseplates and support assemblies designed for bench-top, workstation, or display rack mounting, making them practical to deploy in both classroom and lab environments.
DAC Worldwide's dissectibles are distinct from their cutaway line in one critical way: cutaways show learners what is inside, while dissectibles let learners find out for themselves. Both serve important and complementary roles in a complete industrial training program.
Pumps, compressors, and valves dissectibles
This is the largest and most comprehensive category in the DAC Worldwide dissectibles line, covering the pumps and valves that maintenance technicians encounter most frequently across process, oil and gas, and industrial facilities.
The ANSI Centrifugal Pump Dissectible is an actual industrial Goulds-type pump providing realistic training in the disassembly, inspection, packing, and reassembly of the most common type of centrifugal pump found in process facilities. The Vertical Centrifugal Pump Dissectible covers the common close-coupled, in-line vertical centrifugal pump configuration found throughout all process industries. The Double-Suction Split-Case Centrifugal Pump Dissectible provides training in the construction and maintenance of larger split-case pump designs. The Downsized Horizontal Multi-Stage Centrifugal Pump Dissectible enables field or bench-top disassembly, inspection, and reassembly of multi-stage pump configurations. Additional pump dissectibles cover submersible vertical pumps, hydraulic diaphragm pumps, external gear pumps, canned sealless centrifugal pumps, air-operated diaphragm pumps, Diaphragm Pulsa pumps, and more.
For valve training, the Extended Dissectible Valve Assortment is a comprehensive package of eight common industrial valves that maintenance technicians encounter regularly, including gate valve, globe valve, ball valve, butterfly valve, control valve, check valve, plug valve, and safety relief valve dissectibles. Each allows complete disassembly and basic maintenance activities, and the assortment includes a textbook and illustrated hands-on exercises. Individual valve dissectibles are also available separately, including the Control Valve Dissectible and the Enhanced Control Valve Dissectible, which supports realistic disassembly, inspection, and reassembly of a full-size industrial diaphragm-actuated control valve. The Gate Valve Dissectible covers the 2 to 2.5-inch gate valve found across industrial piping systems.
Mechanical drives dissectibles
DAC Worldwide offers one of the most extensive gear reducer dissectible lines available, covering the major gear reducer types found in industrial drive applications. Available configurations include right angle worm gear reducers, right angle straight bevel gear reducers, right angle spiral bevel gear reducers, in-line helical gear reducers, parallel-shaft helical gear reducers, offset in-line helical gear reducers, shaft-mounted hollow-shaft helical gear reducers, and cycloidal gear reducers. Each is an actual industrial gear reducer restored and prepared for classroom disassembly and reassembly training, giving maintenance technicians hands-on familiarity with the specific internal construction, bearing arrangements, and sealing systems of each reducer type.
Heat transfer and steam dissectibles
The Steam Turbine Dissectible is a complete actual industrial steam turbine originally manufactured by Worthington, Elliott, Coppus, Terry, Dresser-Rand, or comparable manufacturers, used on industrial equipment such as pumps, fans, blowers, and air compressors. The dissectible is mounted on a steel baseplate and support assembly and allows for convenient training in disassembly, maintenance, and reassembly of a steam turbine at a minimum 25 HP scale. It is delivered with a heavy-duty product support and transport cart and a manufacturer's maintenance manual, providing a complete training package for one of the most skilled and consequential maintenance tasks in process facilities.
Process control and instrumentation dissectibles
DAC Worldwide's process control dissectibles extend hands-on learning into the instrumentation domain. The Liquid Level Gauge Sample Dissectible, Sight Flow Indicator Sample Dissectible, and Variable Area Flow Meter Dissectible give learners hands-on experience with the common field instruments they will work with throughout their careers in process operations and instrument maintenance. The Control Valve Dissectible and Enhanced Control Valve Dissectible support detailed training in the disassembly and reassembly of process control valves. Pressure Control Switch and Pressure Switch Dissectibles cover the electrical pressure sensing devices used across industrial and process environments.
Oil production dissectibles
The Representative Triplex Plunger Mud Pump Dissectible covers one of the most critical and challenging pieces of equipment in the drilling industry, giving drilling and production technicians hands-on training with the internal construction and maintenance procedures of high-pressure triplex pump systems.
Who uses DAC Worldwide dissectibles
DAC Worldwide dissectibles are used by industrial maintenance programs at community colleges, oil and gas company training departments, refinery and chemical plant maintenance training facilities, power generation maintenance training programs, military technical training centers, and workforce development programs preparing learners for careers as industrial maintenance technicians across process industries.
They are particularly valuable for programs that lack access to decommissioned or surplus equipment for training disassembly, providing an equivalent hands-on experience in a purpose-built training format that can be used repeatedly without damage or safety concerns.
Why dissectible training matters
The gap between a maintenance technician who has read about pump disassembly and one who has actually removed an impeller, inspected wear rings, replaced packing, and reassembled a pump correctly is a gap that employers measure in reduced downtime, lower maintenance costs, and fewer repeat failures. DAC Worldwide's dissectibles allow programs to close that gap in the training environment rather than leaving it to be addressed through expensive on-the-job trial and error.
Beyond individual skill development, dissectibles support standardized, repeatable training procedures that ensure every technician in a program develops consistent competency in the maintenance tasks their job requires.
