GIn 1698, Thomas Savery obtained a patent for a pump which displacedwater by steam within two chambers. Because of the sometimesviolent and rhythmic vibrations which this device produced, it becameknown as a pulsometer (Figure 1.1). Two similar devices had been builtby Santorio in 1626 (Rogers, 1905) and by Edward Somerset in 1628(Greene, 1913), however Savery's pump was the firstto use automaticvalves, which made it of practical use for such applications as minedrainage.In 1705, Newcomen and Cawley utilizedthe work of Papin and Saveryto develop their "Atmospheric Engine" (i.e., steam piston) which theylater connected to a piston pump via a rocker arm giving it much the sameappearance as a modern oil well pump. Leopold, in 1720, connected the __// ,/,A'steam piston directly to the water piston and strengthened the designto increase steam pressure and thus, performance. _rIn 1730, Demour designed and built the verticsl'pump in Figure 1.2which was the early basis for axial/mixed,Flow rotodynamic devices. Theinclined tube rotated at 60 rpm, lifting 80 gpm six feet (Greene, 1913).About this same time in Paris, Gosset and Deuille took the bellowsprinciple, combined it with a leather flap-valve and manually-operated,reciprocating,piston, and developed the first diaphragm pump. The i8thcentury,a'lso saw the air lift method of Hero, first used practically in/yk&
