USING FREE WIND ENERGY, FOR HOME OR LIVESTOCK. Easy-to-install airlift water pumping windmills save money. Use airlift water pumping windmills for pond aeration and pond filling. Airlift water pumping windmills are economical and easy to use, are better built, and better-performing. An airline from an engine-driven air compressor can be T-ed into the airlift water pumping windmill for low wind energy days.  Two California manufacturers are Airlift Technologies and BowJon.

AIRLIFT  TECHNOLIGIES   AIRLIFT Technologies is a California based airlift water pumping windmill company started with the purpose of  providing an effective, low-cost solution to the worlds water pumping needs.  Other windmill designs are limited in their water pumping capabilities. Our windmill pump is designed without the use of leathers, or plunger type assemblies, therefore, there are no moving parts down in the well that have to be replaced year after year, The only maintenance is to change the oil and clean the filter on the compressor annually. Other windmills must be placed over the well the AIRLIFT water pumping windmill can be placed anywhere the wind blows the best, up to 1/4 mile away for maximum water pumping capabilities, so it is very cost effective.   The unique AIRLIFT injection pump can run dry accepting sand and sludge without harm, we are so confident in the durability of our pump that we guarantee it for life under normal use. Another added benefit of the AIRLIFT injection pump is that it tends to oxygenate and purify the water as part of it's pumping process.  No screen door springs on AIRLIFT Technologies windmills. An industry first. The incorporation of a compression spring housed inside the gas charged shock assures safe, smooth and consistent operation in the worst weather condition The AIRLIFT's unique pumping system is capable of pumping up to 8 gallons per minute and has a maximum lift of 300 vertical and 500 horizontal feet. You can even use more than one windmill to service the same well or vice versa. Both AIRLIFT windmill models are designed to be installed by one person in less than a day with no special tools or equipment.  F.A.Q.'s Q. How does air lift water? A. 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. Q. What is the predetermined depth?  A. Also known as the submergence ratio:  0 to 50 ft. lifts = 30 ft. minimum submergence below water level.  50 to 150 ft. lifts = 70% submergence below water level.  150 to 300 ft. lifts = 50% submergence below water level. Q. What if  I have a shallow well and can't meet the submergence ratio?  A. Then the AIRLIFT positive pump should be used.   Q. What size does my well casing need to be?  A. The AIRLIFT injection pump can accommodate well casings as small as 2". Q. What kind of piping do I need to use ?  A. Common schedule 40 PVC or flexible poly hose. Q. How long does the compressor operate before needing to be rebuilt? A. 6 to 8 years. Q.What maintenance is required?  A. Change the compressor oil and clean the air filter annually.  Q. How much wind do I need?  A. 4-6 mph cut in speed, 7-8 mph pumping begins,  10-15 mph ideal pumping conditions.     AIRLIFT SPECIFICATIONS   Blades 10' or 7'4" diameter blade span.

BOWJON WIND-POWERED WATER-LIFT SYSTEM BOOSTS YOUR WATER SUPPLY AND CUTS YOUR ENERGY COST! Solve your water supply problems for rural home...Livestock watering on range or feedlot...Pond aeration, De-Icing or Drainage AN ENERGY EFFICIENT WIND POWERED WATER DELIVERY SYSTEM PROVEN FOR OVER 20 YEARS NEED NOT STAND OVER THE WELL ...PLACE IT WHERE THE WIND BLOWS BEST. Unlike any other windmill water pump in the world, the bowjon does not have to stand over the well or water source.It can be positioned wherever the wind achieves maximum velocity on a continual basis...up to 1/4 mile from the wellhead.

EFFICIENT WATER-LIFT SYSTEM CUTS COSTS DRAMATICALLY. The Bowjon`s unique pumping system is capable of effectively lifting water up to 8 gallons per minuteand a maximum lift of 300 feet vertical lift. more than one windmill can service the same well. It is a "new "system based on a centuries old, established principle. Bowjon calls it the "air injection" pump. The system is designed to supply adequate water to household, livestock, drip irrigation systems, pond aeration, pond deicing. The Bowjon`s quality materials and durable construction afford long, trouble-free life with low maintenance costs.

NO MOVING PARTS IN THE REVOLUTIONARY BOWJON PUMP. The few moving parts in the entire Bowjon system are all above ground. There are no cylinders or plunger assemblies as in other systems. The only maintenance is to check the compressor oil every 6 months and clean the filters. Bowjon uses a heavy duty P.K. Lindsey industrial type air compressor with TIMKIN®bearings. Bowjons 5 blades are made of 6061-T6 tempered aluminum, each consisting of 3 layers for the maximum strength. They have a varied pitch giving low wind start up torque at 4-6mph, optimum performance at 10-15 MPH. A turn-out assembly with shock dampener allows the unit to slowly turn in and out of the wind to prevent whipping action. This promotes longevity for the windmill. The pump , unlike others, can be run dry without harm. It can accept silt, sludge and sand without damaging the unit. Bowjon`s new technology represents a major advance in the discovery of clean, economical alternatives for energy.
 

EASILY INSTALLED AND EASILY MAINTAINED. Bowjon windmill units consist of either 6'8" or 8'8" diameter 5 blade propellers. Its simlicity of design and engineering allows the unit to be installed by one man with comparitive ease in less than a day. Unlike others, no rigs, special tools or equipment are required. The windmill may be mounted on a recommended 21' to 30' four inch diameter pipe. It can also be constructed on a trailer to be mobile. PROVEN PERFORMANCE ON FARMS, RANCHES, RURAL HOUSEHOLDS. Todays great need for good, clean well water can now be met with this efficient water-lift system. The Bowjon wind-powered water pump is designed for both human and livestock water consumption. Additional benefits are that the water tends to be purfied and oxygenated with aeration.

A SMALL GASOLINE AIR COMPRESSOR CAN BE USED ON DAYS WITHOUT WIND, AS NECESSARY FOR BACKUP.

Solaire Airlift Water Pumping Here is a way to pump water with no moving parts in the well. Solar-powered air compressor  can be used alone or combined with  Unit shown is housed in a portable container. Just connect air line and solar panel. Includes start/stop control, regulator. Compressor automatically starts/stops in response to sun. 1. To boost water flow by adding air flow to an existing Bowjon and Airlift systems, connect using tee in existing airline 2. For solar water pumping, and no wind turbine is being installed, simply connect the Solaire compressor to an airlift pump (eductor) near bottom of well, per lift -to-submergence table. (Or connect to a reciprocating-type, positive-displacement pneumatic pumping motor) 3. For pond aeration, simply connect air outlet to submerged perforated pipe.

Airlift water pumps are sometimes called bubble pumps, referring to those used in aquarium filtration. These are a little different. The principle is usable for high or low lift, but design of the submerged head (sometimes called an eductor or venturi) changes with application.
