Why "American" Centrifugals 

 Show Highest Efficiencies in 

 the Widest Range of Uses 



It is not alone the most modern type of pump 

 but the highest development of that type that makes 

 ' American" Centrifugals unequalled for economy 

 when all costs are considered. 



Efficiency in a pump in itself means nothing. The ques- 

 tion is how much was the first cost, what is the cost of attend- 

 ance and how much is the expense for repairs including 

 pumping time lost. Greatest economy in a pump means great- 

 est duty done at least total cost and is the only measure of 

 value of a pump. 



American Centrifugals are more economical than any other 

 because they show greatest economy in the end. 



The reason is, we do not recommend one type of centri- 

 fugal for every purpose, but for every condition of pumping 

 we have a type of centrifugal especially designed to meet the 

 conditions. American Centrifugals are made in over fifty styles 

 and in a complete line of sizes in each style. 



But the feature is every style is designed with greatest 

 care to produce flow-lines with the easiest possible curves, with- 

 out a swirl or eddy in the waterways, and sides and edges of 

 impellers and interior of casing are machined true and adjusted 

 with precision to overcome friction and back-flow. 



More than this, the pumps are so designed as to overcome 

 the 'shaft end thrusts and the inner end bearings are water 

 sealed to maintain a perfect vacuum. 



Our booklet, "Irrigation by Pumping," contains 

 valuable information to every irrigator and illustrates 

 and describes the largest irrigation pumping systems 

 in America. Mailed free on request. 



Our General Centrifugal Pump Cata- 

 log No. 117 is the most complete ever issued.
