External gear pumps are rotary positive displacement pumps that move fluid using two meshing gears within a closely fitted housing. As the gears rotate, fluid is carried around the outside of the gears from the inlet to the discharge side of the pump.
These pumps provide a consistent flow and are commonly used to transfer lubricating oils, fuels, chemicals, polymers, and other relatively clean fluids. Industrial maintenance technicians must understand their construction, close internal clearances, operating principles, and maintenance requirements.
DAC Worldwide’s External Gear Pump Dissectible (275-135) is constructed from an actual industrial pump restored for realistic classroom and laboratory training related to process pumps. Well-known industrial brands and models are selected according to availability and training relevance.
The dissectible allows learners to explore the construction, operation, inspection, disassembly, and reassembly of an external gear pump. Its primary components and operating features have been retained, and replacement hardware is provided where necessary.
The pump is cleaned, restored, and painted with a high-durability urethane coating where appropriate. It is supported by a welded-steel frame and mounted on a modular, powder-coated steel baseplate.
The baseplate includes provisions for benchtop use or installation on compatible DAC Worldwide workstations and storage rack products.
Learners can use the dissectible to explore:
Product appearance and specifications may vary according to the make and model of the industrial pump supplied.
