A Larger Quantity of Water 

 From A Deep Drill-Hole 



than is produced by any other kind 

 of pump except the Air-Lift and the 

 Air-Lift will require a much larger 

 quantity of power for the same 

 amount of water is delivered by the 



"American" Turbine 

 Centrifugal - 



IT adapts the centrifugal principle 

 of pumping to conditions where no 

 other type of centrifugal can be suc- 

 cessfully used. 



Sand or silt which rapidly destroy the valves 

 in any of the plunger types of pumps do not 

 materially affect the capacity or efficiency of 

 this pump. 



Since there are no valves to wear out this 

 pump maintains practically its original efficiency. 



The submerged bearings are kept perfectly 

 lubricated by an improved oiling device which 

 conveys oil from the surface and there is practi- 

 cally nothing to get out of order as there are 

 no moving parts in the well except the impellers 

 keyed to the main shaft. 



"American" Turbine Centrifugals are made 

 in sizes to operate in wells 12 to 30 inches in 

 diameter, inside of casing, produce best results 

 on heads to 200 feet and deliver from 700 to 3,000 

 gallons of water per minute. 



These pumps develop up to 70 per cent effi- 

 ciencies and are especially adapted for pumping 

 large, deep wells in water-works, manufacturing 

 plants and for irrigation purposes. 



"American" Turbine Centrifugals are 

 described in Catalog No. 117, the most 

 complete centrifugal pump catalog pub- 

 lished. Write for a copy today.
