PROBLEM TO BE SOLVED: To provide a double gear pump easy to machine a shaft hole with combining gear pumps of large displacement difference. SOLUTION: This double gear pump has gear mechanisms 1a, 1c and 1b, 1d meshing a pair of gears stored in two independent pump chambers, has drive shafts pivotally supporting gears in a drive side of each gear mechanism 1a, 1c and 1b, 1d connected and feeds oil introduced to a suction port provided on each gear pump A1, A2 to a delivery port provided on each gear pump A1, A2 by each gear mechanism. Distribution of delivery capacity on each gear pump A1, A2 at a time of synchronized rotation is established by changing delivery quantity per unit tooth width of the gear.
