Types of automotive water pumps| read to know!

This water pump is a simple centrifugal pump that is ambitious by a belt connected to the machine’s crankshaft. The automotive water pump circulates the fluid when the motor is running. The pump is vital to the operation of a car engine as it confirms that coolant flows through the radiator, cylinder head, hoses, and cylinder block and upholds the optimum automotive operating temperature; a belt generally drives it from a crankshaft pulley or sprocket.

An automotive pump uses centrifugal force and impeller edges to move coolant through the several hoses and channels that mark the cooling system. After the coolant runs around the engine, generally at the front of the car, it can wash down to the radiator, where air movement cools the hot coolant along with the radiator fins. Then it leaves the radiator and returns to the water pump, where the procedure starts over.

Different types of automotive water pumps

To know water pumps in detail, it is vital to differentiate between the various types that exist. On the other side, it is good to distinguish between water pumps for trucks or industrial vehicles and passenger cars, each adapting to the specificities of the car. On the other hand, the manufacturers categorize them as follows:

Mechanical water pumps

In mechanical water pumps, the coolant grips heat from the engine block and cylinder head and discharge it to the ambient air by the radiator. Depending on the construction type, you can place mechanical water pumps in the pump housing itself on the outside of the engine or seat them directly on the engine block. Usually, V-belts, timing belts, or directly from the motor drive the mechanical water pumps.

Variable water pumps

The main peculiarity of variable water pumps is that they allow the flow rate to vary depending on the engine’s needs; this is done through a vacuum process. That is, the automotive water pump acts on the cooling system only when necessary. In this way, it helps increase the engine’s efficiency, which translates into lower fuel consumption and, therefore, a significant reduction in pollutant emissions into the atmosphere.

Electric water pumps

Electric water pumps help decrease emissions from recent engines. A supply flow self-determining the number of revolutions of the motor allows cooling according to requirements. It reduces the power necessary and therefore diminishes friction losses, petrol consumption, and emissions of pollutants.

Auxiliary water pumps

The primary function of the auxiliary water pumps is to support the core water pump. However, the extra water pump is more intensive on comfort, as you can locate it in a by-pass hose of the primary cooling system and energies the coolant to the heater inside the car.

Many vehicles may have more than one auxiliary pump, contingent on the complexity of the cooling system. You can use these additional water pumps in hybrid and electric cars to bring coolant to all corners of the system. The batteries are also chilled, as are the electric motors.
