Abstract: PURPOSE: To provide a plunger pump rationalized in arrangement of a reservoir, an electric motor and the like, and in a production cost. CONSTITUTION: A radial plunger pump 1 has a pump housing 2 provided with radial cylinders 6 within it, and a plunger 7 for reciprocating in each the cylinder 6 through an eccentric rotor 11. The pump assembly integrally comprises the radial plunger pump 1, an electric motor 40 for driving the rotor 11 of the radial plunger pump 1, and a reservoir main body 20 for hydraulic oil. The reservoir main body 20 and the electric motor 40 are installed on the same side of the pump housing 2. One side face of the reservoir main body 20 contacts with the pump housing 2, while the other side face has a recessed part 42. The electric motor 40 is projectingly provided into the recessed part 42 of the reservoir main body 20, while the reservoir main body 20 fixes the pump assembly to a support.
