Abstract (en)
[origin: EP2662568A1] [Problem] An electrical pump apparatus is provided in which a situation where a failure detection circuit becomes inoperative before detection of a failure of an electric system can be avoided, and the certainty of failure detection can be enhanced. [Means for Resolution] An attaching portion 63 which is to be attached to a vehicle body 61 is formed so that, in a state where an electrical pump apparatus 1 is attached to the vehicle body 61, a circuit board 51 of a control device 5 is perpendicular to the horizontal direction. A control IC chip 53 which constitutes a microcomputer 72 for detecting a failure of the electric system is placed on a circuit board 51 so as to be higher in the direction of gravity from a lowest water level Hmin at which flooding in a housing 2 causes the electric system to be short-circuited.
