Sun Pumps tries out new pond fountain

When the temperature hovers around the 100-degree mark, even visual elements, such as a fountain spraying water upward, can make one feel a bit cooler. This was the case Wednesday afternoon at Sun Pumps, a solar-energy system provider



Engineer spots power in county's sewage effluent

At first, the idea was to use the generating capacity of nuclear power plants at night, when demand was low, to pump water up for release during the day. When nuclear plant construction stopped, the idea became to arbitrage the difference it cost to



Air Quality Concerns Threaten Natural Gas's Image

Massive stores of natural gas that lie underneath big portions of the United States offer a cleaner source of electricity to a country that relies heavily on coal, but producing all that gas also can pump lots of pollution into the air.

Water Pumps – Types Of Water Pumps | Deosaie Articles

Water pumps are essential to buildings, homes and industrial plants for supplying water from underground sources. The precise ways they work rely on the nature of use that they are required for. There are as many types available today because there are many purposes that these pumps serve.

The simplest water pumps are known as well pumps and are regularly used for providing water to households and buildings or structures. The water is acquired from an underground source and the capacity with which it is supplied through the pump is dependent on how much water is needed. For example, in a home, the number of kitchens and bathrooms will have to be taken into account for your water requirement to be determined. The pumps themselves are buried underground but they move water through motors that are placed above the ground. For taller structures such as buildings or skyscrapers, in order to ensure that the right amount of pressure can be exerted to to supply water to areas that high off the ground, pressure tanks are used. As we know, a greater amount of force is required to push water enough to reach areas that are elevated. To remove water that collects in home or building basements, the third type of these machines is used, and they are called sump pumps. Sump pumps are used to drain water that may have pooled in lower-lying areas of structures.

To get these water pumps, one can choose between a traditional AC- powered and a solar DC-powered source. There are, of course, advantages to solar water pumps. One is their ability to work at lesser power, thus, eliminating the risk of overheating. They also do not need an electrical line nor pipes as they rely mainly on photovoltaic solar panels running on DC power, and they are easy and cheap to maintain. Solar water pumps are apparently very useful in rural farms or ranches where electricity is not readily available. On top of these, these pumps are environment-friendly in that they do not end up in CO2 emissions which bring hazard to the ozone layer. Even in urban areas, even when electricity goes out, a solar pump can come in handy because they can still operate.

There are two basic concepts you should consider before deciding which one is more suitable if you are planning to buy a solar- powered water pump. Direct direct-coupled solar pumping systems only work when the sun is up because it is one whereby the solar power is provided directly to the pump from photovaltaic panels. Therefore, how much water can be pumped depends on how much sunlight there is and, of course, the kind of pump itself.
