Water Lifted By Compressed Air
For Municipal, Manufacturing, Irrigation or Other Water Supply

THE “AIR LIET” SYSTEM. PAUSING recent years much progress has been made in the art of pumping water by compressed air. The Ingersoll-Sergeant Drill Company has done pioneer work in this line, having been the first to employ Dr. Julius J. Pohlé, who is acknowledged to be the original inventor of the “Air Lift.” At first all systems for lifting water or liquids by compressed air were admitted to be extravagant, but with a large experience now behind us, and with marked improvements in air compressor economy, the Air Lift has made valuable strides. We have found that a properly installed Air Lift System requires the attention of the engineer, who should, in the first place, specify a suitable compressor provided with automatic attachments, and he should design the air and water pipes to accom- plish the best results. Each case should be treated by itself, and advice given in accordance with the conditions that exist in each well to be pumped. We have an experienced corps of engineers, and are prepared to furnish specifications and advice free of charge. Patents. The Ingersoll-Sergeant Drill Company owns all right, title and interest in the Pohle Air Lift patents. These patents are broad and protective, covering the most economical means by which water is lifted from wells by compressed air. There are many systems in use, but those familiar with the subject admit that the “Pohle System” stands supreme in its simplicity and economy. The “Pohle” patents cover broadly many other systems, and persons are hereby advised that, in using1 any system which infringes the patents owned by this company, they are doing- so at their own risk. 7
