Every pumping task should have an optimum capacity and pressure requirement. Determining the optimum and selecting the pump that delivers it is the key to an efficient and economical irrigation system operation. Successful agriculture is dependent on having sufficient access to water.
Sources of irrigation water can be groundwater from the wells, surface water pumped from rivers, lakes, or reservoirs. The source of the irrigation water determines what types of pumps should be selected. Deep well submersible pumps are specially designed to pump water from several metres underground, and a variety of pumps can be used when pumping surface water.
