As can be seen from the image below, the Stuart pump is very accurate to the real thing. This type of pump is used for lifting oil from deep wells, pumping from this depth at speed is would require a large power source, so by gearing the power source down and running the pump slowly, a smaller engine can be used. The stuart model also incoporates gearing to run the pump at a realistic speed from the high speed developed by most Stuart steam engines. The pump itself is suspended at the bottom of the well on the end of a very long rod, this is very heavy. very heavy so large counterweights are fitted to slow the pump being lowered and reduce power required to lift it. The pump rod is suspended by wires from the pump head, these lay against the curved end of the head as the pump head is raised to maintain a vertical pull on the rod.
