New airlift pump to lift water 4-5 feet at 4,000 gallons per hour.

I am setting up a new AP system, 2,000 gallon fish tank and 2,000 gallons of float tanks and media bed.
Highest beds are 4-5 feet above top level of the fish tank. 'air lift pumps please.

Airlifts are not designed to lift water much more than 1 foot above the standing water level. It would be very difficult to pump water to 4-5 feet above the fish tank. You would probably be better off with a water pump if you need to lift the water that high. Have a look at this article for more information.

You showed airlifts without any, or much submergence. What if i can have 6-8 feet of submergence and then lift 4 feet? Or use Geyser or Burper pumps like the Aquazwen from Glen Martinez? I need help sizing.

Many thanks for your reply.


In an attempt to promote and improve the economics, safety and security of our aquaponic systems we started developing efficient airlift-pumping technology that will replace both water pumps and air pumps that were dedicated only to air stones. In the “Aquaponics: New Paradigm Shift with Airlift” webinars hosts by the eXtension community, we presented a variety of airlift pumping systems that can be used for aquaponics, backyard and commercial farming. During our presentation on August 12, 2013 went through the various airlift pump systems that were developed by Glenn Martinez of Olomana Garden and concentrate then on the “How To” of one particular system.
