some by American Deep Well 



wells deliver 500 gallons per minute and one 400 gallons per 

 minute. Average pumping depth is 73 feet and 500 gallon 

 pumps are operated by 20 horse power motors. 



But the important point is the main shafts and impellers 

 are supported by roller thrust bearings at the surface, all 

 oiling is done at the surface, there is nothing in the well that 

 can get out of order and a permanent water supply is pro- 

 vided of greatest reliability, with least attendance, smallest 

 expense for upkeep and the assurance that the water is pure. 



"American" Centrifugals are made in types to meet 

 nearly every pumping condition. Complete catalogs for the 

 asking. 



Difficult Water Supply Conditions 

 Are Met with American Centrifugals 



The highest development of the centrifugal prin- 

 ciple of pumping and the application of this 

 improved design to all styles of centrifugals enables 

 the "American" centrifugal to successfully meet the 

 mose difficult water supply conditions, 



At Tulsa, Oklahoma, the city water is obtained 

 from wells which will not deliver a large quantity of 

 water. The situation is successfully met by 

 "American" centri- 

 fugals as shown in 

 the accompanying 

 views. 



There are five 

 wells located a con- 

 siderable distance 

 apart, two of 

 which and the sub- 

 station are illus- 

 trated. Some of the 

 wells are pumped 

 by American verti- 

 cal centrifugals and 

 Turbine Centrifugals. Four
