This wall-mounted demonstration assembly allows for classroom demonstration relating to the above ground mechanical actions, as well as the downhole pumping principles of a typical pumping unit as found in oil fields, worldwide.

The complete assembly, fabricated from engineering plastics, clear acrylic, and nonferrous metals is wall-mounted on 3 primary PVC backplanes. Field installation is required.

A complete, to-scale, aluminum and PVC walking beam assembly is provided, matching the geometry and stroke of well-known well-known industry-standard pumping units. A representative trunnion/center bearing, Pitman arm assembly with equalizer, crank, and gear reducer is provided to faithfully duplicate the working mechanism of a conventional beam pumping unit.

An additional wall-mounted assembly depicts the wellhead, tubing, representative casing, and the working down-hole pump.

An optional component Set can be purchased to allow liquid circulation through the system. This demonstrator will enhance instructor-led training related to artificial lift, rod pumping systems, as well as pumping unit design, operating principles, component parts, and basic maintenance.
