This is an invention I came up with of an airlift pump. It has already been invented and the one portion is called a geyser pump, the entire portion is called a pneumatic ejector pump.

My airlift design runs off of a 5 watt aquarium 9Lpm air pump. The device is submerged in less than 12 inches of water (maybe 8 inches of actual submersion) and it pumps water 24 inches above water level. It pumps water to a two foot height at about 8-9 gallons per hour. The height to which the water can be pumped to is limited only by the air pressure the air pump is able to produce.

I plan to use this pump for aquaponics.
