Water is unarguably the most vital commodity for a human being. The uses of water are endless and each has its own significance. From drinking and washing to cooking and cleaning, water is an important component of all these activities.
The sources of water are numerous. In order to extract the precious liquid and use it to its fullest, man devised pumps. Water pumps have been in existence for several centuries. Ever since Archimedes invented the screw pump to draw water, the use of these devices has grown in leaps and bounds. In simple terms, a pump is a device used to move a liquid from one place to another with the help of air pressure. Water pumps are primarily used to draw water from rivers, lakes and ponds. The first water pumps were the hand pumps, which were used to draw water from an underground water table. Later, as technology advanced, more innovative pumps were developed which made the task less cumbersome. However, hand-operated water pumps can still be found in rural areas. The water drawn by these pumps is used for a variety of purposes like irrigation, land and mine draining, fountains, and sump and bilge pumping.
A water pump may be operated by several sources of energy. Today, the most common source is electricity, which helps pump water with the aid of an electric motor. Other common sources of energy include solar energy, wind energy, gas energy and water energy. While solar and wind based water pumps may not provide the same energy as an electric or gas powered water pump, these devices come handy when constant supervision is not possible. Moreover, since these run on renewable sources of energy, the net operating costs are lower.
The price of a water pump depends on its power and its energy source. Care should be taken to pick the right one to fit the task on hand. From fancy fountains to irrigating our fields, water pumps have made a lasting impact on our lives.
