Mechanical coolant pumps directly propelled by the engine continuously transport coolant when that engine is running, even when no cooling is required. Electric coolant pumps and their integrated electronic control, however, are variably activated according to the required cooling needs. They can be used as main, minor or circulating pumps. They operate independent of the engine and as required. The cooling pump does not initially run in case of a cold start. This helps the engine to reach its operating temperature more quickly. Even when idle or after turning off the engine, the electric coolant pump can provide sufficient cooling power since it is not linked to the engine’s RPM. This customized engine cooling reduces power consumption and therefore friction losses and fuel consumption. Electric coolant pumps therefore help reduce emissions in modern cooling systems.

An additional advantage consists in the ability to install electric cooling pumps individually and outside of the engine. They are relatively light and maintenance-free, thanks to the brushless installation. At an operating voltage of 12-360 volts, it currently reaches outputs of 15 to 1000 watts. Coolants reduce the temperature of the coolant pump’s electric motor. A pulse width-modulated (PWM) signal control makes flexible adjustment possible. This, in turn, enables controlling the transported volume according to the actual needs and independent of engine rotation, thus allowing keeping the cooling temperature constant as required by the respective system. Thanks to their inclusion in the wiring system electronics, electric coolant pumps can also be diagnosed. Depending on the drive type (internal combustion engine, hybrid, electric) and the system, one or even several pumps can be installed in the vehicle.

Electrical coolant pumps have many areas of application:
