| Small Solar Pond Pumps |


I have so many people asking me for directions to build a solar aerator for their pond. It's unbelievable the number of people who have a pond and who want to be able to run a small DC 12 volt air pump or fountain using solar power. The idea is great! Use a small solar panel to run a fountain or air pump to move the water and add precious oxygen and increase the circulation in the pond! The idea is sound but the reality of solar power and building a solar pond are quite different. The cost of an effective and reliable solar powered system is many times more than a comparable electric system.

I know I know, often we want to use alternative energy sources because we want to reduce our greenhouse carbonized footprint or whatever it is they call it these days and I agree that it is a noble and worthwhile goal. Unfortunatly the reality is this and I beg you to listen closely before you decide to go on the trail of building your own solar bubbler or aerator:

Solar power is more expensive than an electric system!

Did you read that? Maybe you should read it again? Solar powered aerations systems can cost three and four and five times more than an equivalent electric system. Of course it depends on the cost per kilowatt hour in your state or privince, where I am it is around 12 cents per kw/h, but even at the price of electricity it should be understood that a do it yourself diy solar airiation system will not be cheap as far as the initial purchase goes...but once it's bought you don't pay anything else!!Or do you? DC air pumps will burn out quicker than regular AC air pumps so you can expect to replace your burnt out DC pump maybe every 6 to 18 months..the good thing is is that DC pumps are cheap and you can buy a Thomas DC pump or a SweetH2O pump for between $100 and $500 so the cost of replacing these little beggers isn't too bad!

Used to control and power a DC motor from a solar panel. The unit prevents stalling of the motor under less than full sun condition. The power of the sun is transformed to the motor running conditions so as the sun goes down the motor slows down instead of stalling. Conversely, or as the sun comes up the motor starts running much earlier instead of staying stalled for hours when it could be running. This translates into more running time of the motor where it spends a lot of time working instead of stalled doing no work.

DC air pumpsDC Air Pumps, Commercial-Grade
Finally a Long Lasting DC Air Pump

Up until now most DC air pumps and battery powered DC compressors had limited reliability. Most DC pumps we've seen offer a 3 to 6 month warranty and if you don't know exactly what you're doing as far as setting up your solar aeration system you can quickly burn out your motor.

We have finally found a commercial-grade line of pumps that come with a one-year warranty and these diaphragm, linear air compressors are easy to service and provide long lasting battery or DC current performance.

These commercial-grade DC air compressors offer superb performance and durability. Typical applications include live fish transport on trucks or fishing boats; however, they can also be used in emergency or solar-powered situations. The simple design of these DC air pumps makes them easy to maintain and repair (oilless, easily accessible brushes and diaphragm).

Pigtail wires for connection to your battery or DC configuration included. 60 LPM and 100 LPM models include either plastic or steel housing cases and do not require additonal housing for outdoor use. 30 LPM unit has no housing and must be enclosed for outdoor use but this 30 LPM unit includes a lighter adaptor to fit into car lighter plugs as well as pigtail wires.

All units have a one-year warranty.

Measure the distance from the compressor to the diffusers and you have the length of weighted tubing needed. A few extra parts depending on your installation can be bought at your local plumbing supply store and you can save even more money!


Airstones
6" Airstone with barbed 3/8" hose connectors - $90 PACK OF 4 AIRSTONES
Includes shipping within continental USA.
Air Diffuser, 6" L x 1.5" W, 3/8" O.D. barb (9 mm). Normal airflow range is 0.5 CFM. 0.75 lbs each. Self weighting when using normal tubing lengths
Item # PR-SAS6 (Pack of Four Airstones)

These are highest-quality ceramic-type air diffusers machined from a solid block of glass-bonded silica. Because dust and dirt particles up to 30 microns in size will pass right through these diffusers, there's no need for expensive air filters. And with an air resistance of less than .25 psi, these glass-bonded diffusers are compatible with economical low-pressure blowers. They produce a uniform medium/fine bubble and are very resistant to clogging. And when cleaning does become necessary because of a buildup of calcium precipitate or bacteria, an acid bath restores them to like-new performance. Made in USA.

With their round grain pore structure, low resistance to airflow, uniform porosity and resistance to clogging, these airstone diffusers are clearly the best diffusers available for general aquaculture aeration. Smaller pores don't necessarily produce smaller bubbles. These diffusers are engineered to produce the smallest bubble possible within the constraints of a reasonable service life. In most soft water applications, they won't need to be cleaned for more than a year. Note that water pH in excess of 9.0 will shorten the diffuser life. Self-weighting when used with typical tubing lengths.
9" Airstone with 1/2" NPT connectors - $150 PACK OF 4 AIRSTONES
Includes shipping within continental USA.
Air Diffuser, 9" L x 1.5" W, 1/2" NPT connector. Normal airflow range is 0.75 CFM. 1.35 lbs each. Self weighting when using normal tubing lengths

Other High Rated and Reviewed Solar & DC Air Pumps
Over the years we have tested and evaluated the staying power and effectiveness of many DC 12V and 24 Volt pumps and one thing we've constantly noticed is that no matter what type of pump you buy, these 12V pumps are not going to give you years of service so buy a good cheap one! When I say cheap I don't mean some ebay special deal on a pump made in some far away country without care for product consistancy I mean buy a good qality pond pump that doesn't cost too much because you will be buying replacements every 3 to 9 months of continuos usage. If someone gives you a one year warranty then you might want to take a closer look because the pumps we use have a 3 month and 6 month warranty. That may not sound good...but that is the reality of solar dc systems as the current technology exists.

Thomas Industries - Thomas DC Pumps Reviews Overall Rating = 7/10
Thomas 5010 Air Pump - Thomas Diaphragm Pump 5002 VD BLDC - Thomas 5010 VD DC - Decent Pumps but higher than desired burnout rate and some issues in consistant pump construction. The 5010 series is in the range of 0.09 CFM @ 2.9 PSI which is barely enough to function a single small airstone and we found that parameter least pleasant. The Thomas 12 Volt 1/10hp Air Pump is similar; a good product.

Thomas 007 & 008 Series Air Pumps - Very good pressure delivering over 20 PSI and 0.6 CFM make this series decent but again the units we've seen featured in systems cooked too quick.

Thomas 907 and 2907 Series Air Compressors - These are good quality but high priced and again the inconsistancy of the units makes us a bit nervous but the fact they can deliver 3.2 CFM and 14 PSI make this little grinders seem like a good deal if you can buy a few when they fry.

Pond Report Highest Rated 12v Air Pumps & 12v Diaphragm Compressors Overall Rating = 9/10
We have seen frustration with people building a homemade solar pond aeration system and it usually stems from the heart of the matter: the air pump. We've been using the White H20™ DC Series featuring 12v diaphragm compressors made in the United States of America and smaller Air Pumps imported from partners of White for their 12 volts series who guarantee quality assurance.
WHITE-H20™ DC 12V DIAPHRAGM COMPRESSORS
TOP RATED BATTERY POWERED AIR COMPRESSORS
Building a solar lake aerator isn't that difficicult if you start with a solid and reliable battery powered air compressor. These 12V workhorses have proven to be the most reliable pumps we've reviewed. These are ideal for mobile use, temporary battery-powered aeration in remote locations, emergency aeration during power failures or as the solar powered pump to ensure there are no fish losses.

They are oilless with ball bearing construction and low amperage draw. Make sure your battery system amperage is compatible with the amperage draw of the air pump, see the chart below. Made in the USA these diaphragm pumps are long lasting and come with a 6 month warranty. Replaceable diaphragms and diaphragm repair kits make this low maintenance and allows you to keep the pump running for thousands of hours. Normally the brushes will need to be replaced after around 3,000 hours of usage. The smaller pump, the PR-DC201, will run for about 6 hours off a regular car or truck battery. If you have a solar charger for a battery you can easily build your own solar aerator. The low-cost of the pumps makes it affordable to use several of the units in larger ponds to provide thorough airiation in all regions of the lake or pond.
Keep one of these on-hand in emergency situations when going without a bubbler is not an option!

Disc Diffuser Pond Aerator.Air Pump.9" Membrane Disc Diffuser - $50 EACH
Includes shipping within continental USA.
Normal airflow range is 0–5 cfm. Equipped with 3/4" MNPT. Single disc or multiple discs can be used with linear air pumps, piston pumps, rotary vane pumps or regenerative blowers. Ideal for everything from small ponds to large lakes. Contact us with questions.
Item # PR-ED3271


Practically invisible due to their dark color, these 9 inch membrane discs are engineered for extended performance. The actual disc diffuser bodies are made of high-strength polypropylene with 3/4" MNPT connections to attach to airlines, manifolds or headers. Each diffuser has an avergae of 6,600 engineered air release orifices, 20% more than some comparable models. The special design of the matt, flexible and supple EPDM membrane, with its proprietary thickness taper, results in full utilization of the membrane surface, even at low airflow operations. This results in improved oxygen transfer efficiency, along with maximum operational flexibility. The disc diffuser has an integral "triple" check valve to prevent fluid backflow. Resistance is about 10" H2O when clean. Made in USA. Note: Diffusers are also known as airstones.


Tip: With two 9" discs and some simple plumbing parts and fittings you can build your own assembly. Two discs mounted on a weighted base are sometimes called "aerations assemblies" with brand names like the Vertex "CoActive AirStation" or the AquaMaster Aqua Air "Dual Membrane Diffuser" or the Aeration Technologies "Airpod" or the "AirBoost" or the "SCEPMD2"...you see where I'm going? Add two of these 9" Membrane discs and some plumbing on to a cement block or stone and you have a fancy-pants aerator for much less expensive than a brand name contraption!

**Note: No instructions are included...you must accept that creating and building and setting up a solar aeration system is a very very VERY complicated affair and while we are offering the parts and instructions on how to build your system we cannot provide ANY help or installation guides. If you wish to have a simple, turn-key system then please contact someone else as we are unable to privide any help beyond this list of products and parts. Any failure of the system to function as expressed, implied or as desired is not gauranteed. Solar aeration systems are a very touchy and persnickety project so if you wish to buy or purchase from us then please do so at your own risk. We have provided a list of parts and instructions but do not imply or warranty that this will actually work!

Windmill & Wind EnergyExample of a complete system:

Bergey Windpower's newest product is the 1,000 Watt BWC XL.1. The BWC XL.1 is currently available only as a 24 VDC battery-charging system. However, Bergey expects to introduce a batteryless grid-intertie version (like their10 kW GridTek system) in the late Spring or early Summer. With a rotor diameter of 2.5 meters (8.2 ft) and a peak output of approximately 1,600 watts the XL.1 is intended for the off-grid home market in the U.S. and for rural electrification programs in developing countries. It is also a perfect upgrade system for current owners of micro-turbines, such as the Air 303 or 403. The XL.1 combines a number of advanced technical features, including a completely new airfoil (patent pending), to provide the highest efficiency yet achieved in a small wind turbine at a cost of energy ~ 40% lower than the current price leader. And, the XL.1 carries the exclusive, industry-leading, Bergey 5-year warranty. "We are very excited about the XL.1. We think customers are really going to like this machine" notes Mike Bergey, BWC's president and CEO
