This rare engine was used strictly to pump water, as its horse power was insufficient to do much of anything else. The engine was built to be placed next to a well or cistern with the pump suction pipe hanging down into the water. The water was then pumped up to a storage tank or possibly a water trough for animals. Before discharging the water from the engine, the water was passed through a water jacket at the upper end of the cylinder to provide the cooling required of the Stirling Cycle process. This 6″ Rider-Ericsson, using 1″ pipe on both the pump suction and discharge, was rated at 300 gallons (1136 l) per hour with a 50′ (15m) rise (75′ (23m) maximum). This engine weighs approximately 625 lbs. (283 kgs.)
