摘要：PROBLEM TO BE SOLVED: To provide an aerial air-cooled device of a vertical electric pump for enabling the air-cooled action to effectively function without increasing a load to a pump motor, applicable even to a pump of low speed operation, and performable only by applying a little processing to an existing pump. SOLUTION: This device is equipped with an out cover 4 surrounded so as to form an annular ventilation passage 5 on the outer periphery of a motor case 2; and has an air sending port 6 for upwardly opening the upper end of the out cover 4 in the height in the vicinity of an upper end part of a stator 3 installed in the motor case 2, downward opening the lower end of the out cover 4 in the height in the vicinity of a lower end part of the stator 3 and derived and opened from a side part of a peripheral wall of the out cover 4; and is constituted so that a cooling fan 8 equipped with a small submersible motor 7 is installed on the deriving opening end of the air sending port 6.
