The pump arrangement (100) has a pump (116), a mechanical drive (118) and an electrical drive (108). The two drives are assigned to a common pump. An overrunning clutch (104) is provided between the pump and the mechanical drive. Another overrunning clutch is provided between the pump and the electrical drive. The mechanical drive takes place on the basis of a crankshaft of the internal combustion engine. The electrical drive takes place by electric motors. The electric motor, provided for drive of the pump, has a stator (110) and a rotor (112). An independent claim is also included for a method for the operation of the pump arrangement.
