What is a water pump
The water pump is the heart of the cooling system and is responsible for circulating coolant, consisting of housing (aluminum diecast, cast iron, aluminum gravity etc), flange(forged steel, sintered iron etc), impeller (pressed steel, cast iron, synthetic resin etc), water pump bearing and mechanical seal kit.
Water pumps’ material is depending on performance level, quality as well as customer requirements and working conditions.
Water pump circulates coolant between the engine and radiator to keep the engine from overheating. Inside the water pump is a metal or plastic impeller with blades that push the water through the pump. The impeller is mounted on a shaft that is supported by the pump housing with a bearing and seal assembly. The cooling liquid absorbs the heat from the engine block and cylinder head and releases it into the ambient air through the radiator.
The water pump is usually driven by V-belts or poly-rib belts depending on their installation location in the engine. It’s mounted on the engine block from the outside and can be replaced without having to open the engine itself.
Water Pump critical quality
When water pumps fail, the engine overheats, which can result in serious engine damage. Water pumps are typical wear parts, which must sometimes be replaced several times during the service life of the engine.
Water pumps typically fail one of two ways: the shaft seal starts to leak, or the impeller inside breaks, comes loose or the blades erode and wear down (which is more of a problem with pumps that have plastic impellers).
