In a marine cooling system, the water pump is responsible for circulating the coolant (usually a mixture of fresh water and antifreeze) through the engine to absorb heat, and then through a heat exchanger where it is cooled by seawater before returning to the engine.
The water pump is typically driven by a belt connected to the engine's crankshaft, and its impeller is housed in a housing known as a "pump body." As the impeller rotates, it creates suction that draws coolant into the pump body through an inlet port. The impeller blades then force the coolant through the pump body and out through a discharge port, where it is directed into the engine's cooling passages.
One important consideration in marine cooling system design is the need to prevent seawater from entering the engine itself. This is typically accomplished through the use of a heat exchanger, which separates the engine's coolant from the seawater used to cool it. In a typical heat exchanger design, seawater is pumped through a separate set of tubes or passages that run parallel to the engine's cooling passages, allowing heat to transfer from the engine coolant to the seawater without the two fluids mixing.
