Abstract:
An electric liquid pump includes a casing having a central portion, rear cover and front cover, having an inlet and an outlet for the liquid. The central portion has first and second compartments, with the second compartment in fluid communication with the front cover interior. The pump includes an impeller and an electric motor, for operating the impeller, a stator housed in the first compartment, a rotor, coaxial with the stator, housed in the second compartment and an electronic card for supplying the stator at least partly housed in the rear cover. The central portion includes a plurality of walls delimiting a plurality of gaps in fluid communication with the second compartment and the front cover interior such that the liquid circulates in the gaps. The walls at least partly face the stator such that the liquid circulating in the corresponding gap removes heat from the stator.
