Abstract
An assembly and means for cooling a hydraulic pump comprising an electric fan mounted on a housing of the hydraulic pump. An upper shroud helps direct cooler air to the fan and helps prevent inadvertent contact with the fan blades. An optional controller can be attached that senses the temperature of the hydraulic pump and adjusts the speed of the fan accordingly.
