2021-11-3  What pump materials should be specified for a circulating water pump at a power plant? The location of the power plant often determines the type of cooling water that will be used. Inland plants are typically located near rivers or lakes, which allows them to use freshwater. A coastal power plant may use brackish water or seawater for its circulating water pumps.
