The pump arrangement has a bidirectional pump, which has a first pump port and a second pump port and which can be driven by a pump electric motor. The first pump port is connected to the first cooling circuit, wherein the second pump port is connected to the second cooling circuit. A coolant volume flow which is provided for at least one of the first and the second cooling circuit can be adjusted by changing the rotational speed of the pump electric motor.
