Water Pump

Water pumps are critical components of vehicle coolant circulation systems, typically engine-driven via belt or chain. These pumps utilize an impeller to generate flow, transferring coolant from the radiator through the engine block to regulate operating temperature. Construction commonly features a sealed housing containing the impeller, bearing(s), and a mechanical seal to prevent leakage. Materials include cast iron, aluminum, and plastic for housings, with stainless steel or ceramic seals for durability. Modern designs may incorporate electric motors for on-demand or supplemental coolant flow, particularly in hybrid and electric vehicles.
