Marine centrifugal pumps are robust, high-efficiency pumps designed for seawater and other fluid transfer in marine applications. They feature corrosion-resistant materials to withstand harsh marine environments. These pumps are essential for ballast, cooling, firefighting, and bilge systems on ships and offshore platforms.
