The invention provides a quantified and axial plunger pump. The plunger pump is a radial flow distribution pump and comprises a transmission shaft, a cylinder, a flow distribution sleeve, a flow distribution shaft and an inclined disc, wherein the transmission shaft is driven by external force to rotate, the cylinder, the flow distribution sleeve and the flow distribution shaft are connected with the transmission shaft, and the inclined disc enables the plunger pump to output fluid in a quantified mode. The cylinder, the flow distribution sleeve, the flow distribution shaft and the transmission shaft are coaxially arranged. Compared with a traditional radial plunger pump, the plunger pump has the main advantages of being simple in structure, small in size and light in weight; compared with a traditional axial plunger pump, the plunger pump has the main advantages that the rotation speed of the pump can be substantially increased, working pressure can be substantially increased, the nominal flow rate can be multiplied, or at equal working pressure, the volume efficiency of the pump is remarkably improved, and noise can be lowered by more than10 db.
