Double suction vertical split casing centrifugal water pumps are horizontal, single-stage, axially split case pumps designed for raw water applications in dams, coal-fired power stations, and industrial water systems. These pumps handle clean water or slightly contaminated liquids with physical and chemical properties similar to water, delivering high flow rates with substantial head requirements.
