Water pumps

Water pumps are devices that are responsible for circulating coolant through a vehicle's engine cooling system. Their function is to prevent the engine from overheating and maintain an optimal operating temperature. There are different types of water pumps depending on their mode of operation and their delivery flow. Some examples are:

- Mechanical water pumps**: they are driven directly from the engine, using a V-belt, a timing belt or the crankshaft itself. The pump's power consumption increases with the engine's speed, which means higher fuel consumption and polluting emissions.

- Variable water pumps**: allow the flow rate to be varied according to the engine's needs, using a vacuum process. The water pump acts on the cooling system only when necessary, which increases engine efficiency and reduces consumption and emissions.

- Electric water pumps**: are driven by an electric motor that is electronically controlled based on water temperature and other variables. The electric water pump provides high efficiency, precise control, timely and adequate cooling capacity, low energy consumption of coolant flow based on water temperature and other information shortens the coolant flow distance and reduces water pump displacement.

- Auxiliary water pumps**: used to supplement the action of the main pump, especially in turbocharged engines or hybrid systems. Their function is to improve the circulation of the coolant in specific areas of the engine or in additional components.

Water pumps are essential elements for the correct operation of the engine and its durability. Therefore, it is important to periodically check their condition and replace them in case of failure or wear.

There are different brands of water pumps on the market. Some of the best known are:

- Bosch : It is a German brand that offers high quality and durable water pumps, with an innovative design and a good quality-price ratio.

- Metelli : Metelli brand car water pumps are high quality and efficient products. These pumps ensure the proper functioning of the engine cooling system, preventing overheating and wear. Metelli water pumps are manufactured from strong and durable materials, and are subject to rigorous quality controls. In addition, they have an excellent quality-price ratio and a wide range of models compatible with different types of vehicles.

- Aisin: Aisin brand automotive water pumps are high quality, high performance products that provide optimum cooling without creating excessive load on the engine. Aisin's advanced aluminum die-casting technology allows for reduced size and weight without sacrificing cooling efficiency. The highest quality materials are used to create a stronger design and increased durability against corrosion. Aisin water pumps' high precision machining process produces smooth coolant flow channels, efficient rotors, ball bearings and carbon ceramic mechanical seals for optimum performance and longevity.
