An oil cooling system for a motorized pump is described. The motorized pump includes an oil sump and oil flow path, the oil sump and oil flow path containing oil to lubricate and remove heat from a bearing assembly and drive shaft. A motor coupling housing attached to a bearing box holding the bearing assembly includes an interior space that houses an oil cooling system. The oil cooling system includes a finned cooling tube connected to an outlet of an oil flow path in the bearing box. A fan is connected to the drive shaft of the motorized pump, and is situated to force air over the cooling tube and plurality of fins such that hot oil received by the cooling system is cooled and the cooled oil is returned to the oil flow path in the bearing box.
