When People Think Best Centrifugal Pumps 

 They Think "American' 



/CALIFORNIA is the home of irrigation 

 ^*-* in the United States. It was first 

 extensively practised there and it is there 

 that it is in largest use at the present 

 time. 



Early in 1910 the Patterson Ranch 

 Company purchased a tract of 14,000 

 acres in one of the most fertile spots 

 along the San Joaquin River with the 

 express purpose of watering it with the 

 model irrigation pumping system in 

 California. 



at that time and when the Patterson 

 Ranch Company was ready to extend 

 their model plant they chose pumps of a 

 later design as the best produced at that 

 time but these were also "American" 

 centrifugals. 



There are now about 20,000 acres 

 under water on this ranch, pumped by 

 about 30 "American" centrifugals of 15 

 and 20-inch rated size, but the 15-inch 

 pumps are equipped with 24-inch suction 

 and 20-inch discharge, and the 20-inch

 Company, California, Equipped with "American" Centrifugal Pumps. 



The plan called for five pumping 

 stations constructed of concrete, five 

 reservoirs lined with concrete and con- 

 crete lined canals of best construction. 



There were about 7,000 acres watered 

 by the original unit which was con- 

 structed in 1910. This was so successful 

 that additional lands were acquired and 

 the plant considerably more than doubled 

 in size during 1912. 



But the important point is that 

 "American" centrifugals were purchased 

 for the original unit as representing the 

 most advanced practice in pump design 



pumps are fitted with 30-inch suction 

 and 24-inch discharge pipes. 



The reason why "American" centrifu- 

 gals have a reputation for quality is be- 

 cause the designs are constantly changing 

 they are built by pump designers and 

 not mere pump manufacturers. Skillful 

 centrifugal pump designers know things 

 today about the performance of centrifu- 

 gals they did not a year ago. Present 

 "American" centrifugals embody present 

 knowledge of centrifugal design. 



"American" centrifugals "keep up." 

 Catalogs 1 17 and 124 tell about them.
