Used extensively within the food, mining, agricultural and pharmaceutical industries, lobe-type positive displacement pumps are self-priming and non-contacting, allowing for effective use with slurries, pastes, high viscosity liquids, as well as in dispensing lubricating oils, fuel oils, gasoline and other petroleum-based liquids.

This sectioned, hand-operated, commercial-duty, positive displacement, aluminum-body, lobe-type pump allows for convenient classroom training in the design, operation, construction and maintenance of these common process pumps used in industry.

Carefully-planned cut way areas and color-coding combine to showcase the internal configuration of the pump. Seal features, hardware locations and bearings are retained, allowing for use in maintenance-related training. This realistic teaching aid will make introductory courses in pump selection, maintenance and operation more productive, realistic and memorable.
