Electric Coolant Pump

The KUS electric coolant pump offers versatile utility, finding application in new energy vehicles (NEV), heating/air conditioning systems, and conventional combustion engine vehicles. It is indispensable for various functions, including cooling transmission systems, aiding turbocharging, and facilitating exhaust gas treatment systems, among other vital roles.

An electric coolant pump plays a pivotal role within automotive thermal management systems. This essential component comprises a pump assembly, a brushless motor, and a controller. The controller actively propels the brushless motor, which, in turn, drives the impeller into rotation. Coolant enters through the designated inlet, and aided by centrifugal force, the liquid pressure escalates, promoting the internal circulation of coolant throughout the system’s pipelines. This process significantly enhances the cooling efficiency.
