These are 'Frequently Asked Questions' about our solar well pumps type LJ10 and LJ20. if you have any others, please don't hesitate to get in touch with us on; If you will help us to marketing this product, please contract us: http://www.liujia.com

A1-A6: you have knowledge about a main well pump and are looking for a solar well pump

B1-B16: you have had experience with a solar pond pump and want to know why the Liujia solar pump is different

Just imagine the supply of water with no running costs and no unsightly or dangerous cables; a pump which takes only minutes to install, and which boosts the oxygen in your well; a really attractive feature for your garden at a competitive price. You've just imagined a solar well pump, which is constructed for supply the water to the activation of pond water and swimming pool water, without shifting to 240 or 110 V AC voltage. Optimally suited to a garden pond area, where primary energy should be saved or is not available because of security reasons.

Put most simply, Solar Power is a way of converting sunlight into a useful energy source, via a small solar panel which 'collects' the light and stores it for use. Solar Power works on light, not heat, and can be used for many, many purposes - the compact panels supplied by solar well pumps are particularly well-suited to domestic uses such as lighting, fans and, of course, garden water features.

There are many! First and foremost, solar power is so simple, all you have to do is connect the panel to the pump, and away you go! There is no need to call in an electrician - otherwise essential, as electricity and water are a dangerous combination. Solar Power is safe for children and pets - no trailing cables or need for circuit breakers. It also means you can site features in nooks and crannies - no need to worry where your mains supply is. And finally - of course - Solar Power is the 'green' option - care for your planet whilst enhancing your garden.

Yes, it's much simpler. You don't need to bury armored cable. You don't need timers or circuit breakers and there is no chance of getting electrocuted. You just put the pump in the water; point the panel toward the sun; plug them together - and that's it! It's also very portable, so if you have another water feature at the other end of your garden or you move to a new house, the solar well pump is really easy to move.

As point 9 in the instruction manual, the following technical arrangements can improve the operation decisively:

1* Take a 30-40 cm long piece of a elastical tube made of silicone or rubber, inner diameter of 10 mm and a thickness of 3-4 mm. Connect the one end with the water outflow of the pump and the other end with water tube. Then stick this connection to the rope. Finished!

2* The elastical tube, two o-rings and the transtition between the two tubes can be delivered as a option, but can also be easily find in home market.

Yes, as long as it's not freezing in the well, works the pump still. kepp only the outway of water not to freezing. you get water also in the winther.

The application haven't been tested yet. Some dealers have already used this pump on open solar thermal systems for water supply. As long as the circulating water temperature is not over 60 degrees and the difference of the daily's temperature between hot and cold water is not over 40 degree, there is no problem.

Our pumps are a low-flow type for the private home sector, not for water supply in field. But it is possible to connect it with a drip irrigation system for irrigating small gardens or fields, depending on the plant sort, sun intensity and the deepness of the waterlevel.

First, the greatest problem is that consumers do not know how to install the pump in a correct way. A supermarket distribution was not a very effective place to sell the pump, because it did not offer the knowledge and service of expert shop. For example, which solar panel suits best for the different needs of the consumers?

Second: The solar pump has been conceived for permanent operation and can be put into operation through out the whole year. If the solar pump after having been put into operation, is not being in the water for a longer period (longer than one week) or it is being stored or break down no matter why. Customer have to put out the pump and clear it.

The strong point of the pump is that it runs even on cloudy days, not only on clear sunny sky. Therefore we have three situations of the height of water / pumping capacity :

full sunshine = 750 mA solar current

a few clouds = 450 mA solar current

it is hazy = 250 mA solar current

With option LJ02-10 or LJ02-20, the pump can supply water even in hazy weather. But most of the small solar pump with circle motor have problems on hazy days, which is the most important reason why most solar pumps have limited use.

This is a piston pump, which inhabits only three moving parts. A Electro-box with a 11 meter cable (22 meter cabel for type LJ20) is already connected to the pump, which is a convenience to the customer.

No. This pump can not run with batteries. The electronic part of the pump is constructed to run with a small solar current -the pump starts up at 30 mA solar current- in the sense of using environmental energy. The battery delivers a very strong current too fast, which would damage the pump immediately. If it is necessary, a option can be purchased for the pump enabling the usage of batteries. But unfortunately, it is not able to withstand harsh environmental conditions.

The pump is only 37 cms long with a diameter of 5,5 cm. With 11 meter cable (22 meter for type LJ20), its weight is ca 5,2 kg. For shipment: 2 pumps for are contained in one carton.

The solar pump cannot be used for any transportation of mud or salt water. In case of recently installed wells, it is necessary to wait until the water clears up. If the transporting water (operation in a river or a lake), it is recommended to attach a simple filter of foam rubber in front of the openings of the solar pump.

Yes, of course. We shall be glad to supply one sample. If you agree with it, we will send you an Order-Form for payment with Master card. After filling put, send it back to us. We will do all necessary procedure for it.

The pump works automatically with sunlight. Usually, there is no need to turn it on and off. The water supply depends on the intensity of sunlight. But, turning on and off frequently will not do any damage to the pump.

No, the pump is not strong enough to suck sand in the water. But in case of recently drilled wells, the well water needs some time to clear up. If the transported water is not always clear, (operation in a river or a lake), it is recommended to attach a simple filter of foam rubber in front of the openings of the solar pump.
