The Sullivan Air Lift Pumping System

Sullivan Booster on one of three wells at Sharps- burg, Pa. Horizontal discharge line 1350 ft. long; final elevation, 25 ft. The accompanying illustrations and notes show some of the instal- lations of this character that have been made by this company. More detailed reports on these and many other similar booster plants are also available. The Air Lift for Acids and Chemicals The air lift is admirably adapted for pumping acids, slimes, pulps and other solutions containing chemicals which rapidly eat out the working parts of mechanical pumps. For service in connection with Pachuca tanks, flo- tation and other wet ore dressing systems, the air lift is very desirable. Advantages secured in handling such liquids by this method, as em- bodied in Sullivan practice, include fact that this return air is at a lower temperature than atmospheric air and at a slightly greater pressure, secures a decided gain in volumetric effi- ciency. 3. Where the water is discharged at an elevation above the surface, either near or at some distance from the well or wells, a greater gain is secured by discharging the air from the booster or boosters through a mixing tube in the base of the riser pipe, lightening the water’discharge column and reducing the head. Sullivan Booster on a well at Rubsam and Hormann Brewing Co., Staten Island. N.Y.; discarded deep well pump in background. This plant gives 55 gallons per minute instead of 30 gallons, (capacity of old pump) and requires only 13% H. P. as compared with 20. At the same plant, a Sullivan Air Lift Booster was substituted for an Air Lift of another system. The flow in gallons per minute was increased from 50 to 100, with 20 per cent less air. 23
