Groundwater Innovations manufactures a new air-lift pump for developing or purging troublesome wells. The air-lift pump has no moving parts in the water, so particulates of any size are carried through the discharge tubing. Air-lift pumping can lift water more than 33 feet as long as there is sufficient submergence. Under optimum operating conditions, the 2-inch air-lift pump is capable of delivering 5.8 gpm; the technology is designed to deliver reliable production when other pump systems fail.
