An installation of six 14-Inch "American" Centrifugals installed by Payette-Oregon Slope Irrigation Company near Payette, Idaho, for Irrigating 6,000 

 acres and delivering over 50,000,000 gallons or water per day on lifts of 84 and 1 10 feet. 



Why More American Centrifugals Are Installed for Irrigation 

 Pumping Than Any Other Make or Type of Pump 



THEY not only represent the highest devel- 

 opment of the centrifugal principle of pump- 

 ing, combining low first cost with low at- 

 tendance and repaid costs, and the highest 

 efficiencies of this type of pump, but they possess 

 distinctive features which make them superior to 

 other centrifugals. 



bench lands. Pumps deliver water through two 

 36-inch pipe lines, three pumps delivering water 

 into each line, one of which raises water through 

 500 feet of pipe 1 10 feet and the other line through 

 450 feet of pipe 84 feet. 



They are made in special designs to meet every 

 possible condition instead of attempting to adapt 

 all locations to a single style of pump, and they 

 maintain their rated efficiencies. 



Each of the pumps deliver 5,000 gallons per min- 

 ute when operated at a speed of 1 160 R. P. M. but 

 the important point is that the pumps were de- 

 signed especially to meet the conditions and each 

 pump shows a mechanical efficiency of 84 per cent 

 and the overall efficiency of the entire plant is 74J

 There are six 14-inch "American" centrifugals di- 

 rect connected to electric motors which are em- 

 ployed to pump water from an intake from the 

 Snake river to irrigate 6,000 acres of adjacent 



In nearly every irrigation pumping district in 

 the West you will find "American" centrifugals 

 showing greatest economy through their bemg bet- 

 ter designed and especially adapted to meet the 

 conditions under which they are installed. 



American Centrifugal Catalog 1 1 7 is the most 

 complete published. Write for it. 



Consider that thi? water contains a large amount 

 of silt and grit, but due to the large, balanced, easy 

 flow line passages, these efficiencies are not only 

 initial ones but, those the pumps maintain. No 

 other type of pump will equal this economy under 

 these conditions.
