An integrated, i.e unitary, rotary hydraulic vane pump assembly reduces cost and simplifies manufacturing thereof. The integrated assembly includes an electric motor, a rotary vane pump, a pump housing and an end bell. The end bell has an inlet fitting or passageway which communicates with the inlet of the rotary vane pump. The pump housing receives the vane pump and is received within the end bell. The electric motor is secured to the face of the pump housing opposite the end bell. The pump housing includes outlet passageways and a centrally disposed axial opening for receiving an output shaft of the electric motor. The rotary vane pump includes end sections and a center, cam ring section which receives a vane rotor assembly coupled to the output shaft.
