The Cheapest Pump 



When You Consider All the Costs 



Pump efficiency means nothing to the 

 inquiring mind unless all costs necessary 

 to obtain and maintain that efficiency are 

 considered. 



It's the man with the ability to include 

 all costs in his estimate : first cost, foun- 

 dation cost, housing cost, attendance 

 cost, repair cost, pumping time lost cost, 

 and the average efficiency maintained as 

 compared with the .total duty done, and 

 who figures interest on the investment 

 to include foundations, ground and build- 

 ings; who recognizes the greater econ- 

 omy of the 



"American" 

 Centrifugal Pump 



Two to five times the first cost, two to five 

 times the foundation cost, two to five times the 

 ground cost, two to five times the housing cost, 

 two to five times the attendance cost, two to 

 five times the repair cost and an efficiency that 

 in average use is nearly always far below rated 

 efficiency, due to wear in the valves, are points 

 advocates of old style plunger pumps like to 

 ignore. 



American Centrifugals attain up to 82 per 

 cent efficiencies and they not only attain them 

 but maintain them. 



Moreover, they meet practically all pumping 

 conditions larger than a 10-inch deep drill-hole. 



The jeason is that no matter what the pump- 

 ing conditions may be we have a special type of 

 centrifugal especially designed to meet the re- 

 quirements and as an evidence of it we show 

 just a few of our standard types of centrifugals 

 on this page. 



And don't imagine that "American" Centrif- 

 ugals are low head pumps'. Nearly any of our 

 standard types of centrifugals, in medium or 

 large sizes, will maintain their maximum 

 efficiencies as single stage pumps when operating 

 aga ; nst 125-feet heads with an equal increase 

 in head for each additional stage. 



If this all-the-cosl economy interests you 

 sit down right now and write for catalog 1 17, 

 the most complete centrifugal pump catalog 

 published.
