THE DUPLEX
PUMP
Fig. 300.
A practical manual that begins with a historical survey and the principles of hydro-mechanics, hydrostatics and pneumatics, then examines flow under pressure, gravity, and friction. It surveys water-pressure machines, water wheels and turbine types, and hydraulic apparatus including jacks, presses, accumulators and rams. The work classifies pumps and provides detailed, illustrated treatments of hand, belted, electric, steam (single, duplex and compound), centrifugal, rotary, jet and injector types, plus compressors, pulsometers and fire and mining applications. Practical guidance on valves, management, calculations, rules, tables and a glossary round out the text.
