A pump assembly () includes a rotor axle () extending along a rotor axis (R), an impeller () fixed to the rotor axle (), a pump housing () accommodating the impeller (), and a drive motor with a stator () and a rotor (). The rotor () is fixed to the rotor axle () for driving the impeller (). A rotor can () accommodates the rotor (). The rotor can () includes a rotor can flange (). An electronics housing () has a cap () including a first material () forming a front face () of the cap (). The front face () extends essentially perpendicular to the rotor axis (R). The first material () is at least partially overmolded with a second material () at an inner side of the cap (). The second material () is more heat-conductive than the first material ().
