The "American" Deep Well Turbine 



No Matter How Difficult the Pumping Con- 

 ditions May be, There is a Pump Among 

 the "American" Family of Centrifugals Es- 

 pecially Designed to Meet the Requirements 



IT IS NOT alone the development of the centrifugal prin- 

 ciple of pumping to its highest efficiency but producing 

 a type to meet every possible condition that establishes 

 the supremacy of the "American" centrifugal. 



The "American" vertical type Turbine Centrifugal is 

 especially designed for pumping deep bored wells 12 inches 

 and larger in diameter. 



Study the details of construction of the two-stage vertical 

 turbine, direct connected to vertical type motor, in the accom- r* 



panying illustration. /

This is what is known as a No. 24 turbine, and is inserted in ^^ 

 a riveted steel well casing 24 inches inside diameter. 



* 



The pump has 9 inch suction and discharge pipes and is de- 

 signed to deliver 900 to 2500 gallons of water per minute on 

 heads to 100 feet. 



Note the flexible shaft coupling below motor, the water step 

 immediately below coupling which takes care of all end thrust 

 on the main shaft, the pressure lubrication below turbines, ex- 

 cluding all grit from the lower bearings, and the inner casing sur- 

 rounding the main shaft, making it impossible for grit and sand 

 to reach any of the bearings of the pump and making possible 

 the pumping of water containing a large amount of silt and sand. 



Attaining highest efficiency and economy in any 

 kind of pumping is what has made the "American" 

 centrifugal famous. 



"American," Centrifugals are described in Catalog 

 117, the most complete centrifugal pump catalog ever 

 issued. Write for it.

 Pumping," Bulletin 118. 



Special types of turbines are shown in Bulletin 122.
