Water pump

A water pump is an electromechanical machine used to increase the pressure of water to move it from one point to another. Modern water pumps are used throughout the world to supply water for municipal, industrial, agricultural, and residential uses.

Water pumps also are used to move wastewater in sewage treatment plants. Modern water pumps most often are driven by electricity, but other power sources also are used—for example, diesel or gasoline engines. In some remote areas, such as desert regions, solar panels may be used to supply power to small pumps.

Water is very essential for efficient farming. Often such water is found in various sources like borewells, ponds, wells, streams, and rivers. A water pump machine is the most effective means of lifting water from these sources. There are different types of pumps available. Choosing the right type of pump depends upon the suction lift and delivery head.

Centrifugal water pump is most commonly used for agriculture purposes, it is a rotary machine in which an impeller rotates inside a casing, draws in the liquid at its center, and throws out the liquid through an opening at the side of the casing due to centrifugal force.

Pumps are used extensively in agriculture to move water from the water source, which could be a river, dam, or bore, through pipes to either a point of usage or a storage facility, such as a water tank or an irrigation system.

Centrifugal pumps are also commonly used for pumping sewage, because these pumps can be easily installed in pits and sumps, and can easily transport the suspended matter present in the sewage.
