Abstract (en)

[origin: EP1561950A1] The arrangement has a pump (20) comprising a hydraulic part (22) and a pump motor (28) for activating the hydraulic part. A fan (30) for cooling the motor has a suction side (32) and a discharge side (34). A partition (40) disposed between the sides isolates cold air of the side (32) from hot air of the side (34) so that air pulsated by fan on the motor does not directly flow towards the side (32).
