The utility model relates to a double-swash plate type hydraulic motor plunger pump comprising a shell, a stator, a rotor, a cylinder body, a plurality of plungers, two swash plate assemblies and a flow distribution device, wherein a plurality of suction and exhaust oil ports communicated with a plunger cavity are arranged at the left side and right side of the cylinder body respectively, the flow distribution device is in clearance fit with the cylinder body, the swash plate assemblies lead the plungers to do linear reciprocating motion in the plunger cavity when the spindle of the rotor drives the cylinder body to rotate, the flow distribution device is communicated with the suction and exhaust oil ports of the cylinder body periodically, therefore, the flow distribution of the motor plunger pump is realized, and the flow distribution device can not rotate along with the spindle and is of a flow distribution shaft. Due to adoption of the flow distribution device, the integral structure of the pump is effect
