Engine Water Pump
The water pump is powered by the engine and circulates the liquid coolant through the engine cooling system.
Solutions to Water Pump Failure
Leaks and noise are signs of pump failure, which can be caused by ageing and wear or overheating conditions, and are often caused by other faults in the system. It is driven by belts (either dedicated serpentine belts or rarely by timing belts), so proper belt maintenance is critical to its operation.
Leakage
Causes: Improper installation of water pump or improper use of sealing gasket.
Solutions: If it is a new water pump, check carefully remove and reinstall the pumps. Strictly abide by the torque specification and ensure seal gasket is in the right condition.
Rust and Corrosion
Causes: Polluted coolant incompatible coolant or a mixture of coolants of different chemical composition
Solutions: Before installing a new pump, flush the vehicle cooling system components thoroughly. When using sealants, clean the edges and surfaces of parts and apply the new seal evenly along the edges of parts.
Cavitation
Causes: Bubbles form at the coolant inlet of the pump. As the pressure in the system increases, the bubbles can implode and cause damage.
Solution: Replace the pump, Flush the cooling system thoroughly before installing the new pump and refill the system with the correct coolant recommended by the vehicle manufacturer.
Internal-accumulated sediment
Causes: Contaminated coolant incompatible coolant or a mixture of coolants of different chemical composition
Solution: Replace the pump, Flush the cooling system thoroughly before installing the new pump and refill the system with the correct coolant recommended by the vehicle manufacturer.
Application of Water Pump
Thermal management of powertrains of Conventional Inter Combustion Engine
The engine drives the mechanical water pump to provide circulation power, and the thermostat controls the circulation switch.
Thermal management of new energy vehicles
Electric Water Pump is our target product lines in the future.
For electric vehicles and selected hybrid applications, electric pumps are solution to ensure correct temperature management of inverters and battery packs.
