How does air lift water?
Air lifts water by a combination of submerging the pump to a predetermined depth and injecting air into the pump casing, mixing with water, creating hydro-static pressure, forcing the water-air mixture as high as 300 feet. What is the predetermined depth? Also known as the submergence ratio: 0 to 50 ft. lifts = 30% minimum submergence below water level. 50 to 150 ft. lifts = 70% minimum submergence below water level. 150 to 300 ft. lifts = 50% minimum submergence below water level. What if I have a shallow well and can’t meet the submergence ratio? Then the AIRLIFT positive pump should be used. NOT the AIRLIFT air injection pump. What size does my well casing need to be? The AIRLIFT injection pump can accommodate well casings as small as 2″ ( 2 inches). What kind of piping do I need to use ? Common schedule 40 PVC or flexible poly hose. How long does the compressor operate before needing to be rebuilt? 6 to 8 years. What maintenance is required? Change the compressor oil and clean the
