The present invention relates to a pump control device and a pump system. A controller 26 of a pump control device 20 performs first control for driving a motor 22 such that the rotational speed (N) of the motor 22 exceeds a target value (N1) during the start of operation of a vane pump (18). If an ending condition is satisfied during execution of the first control, the controller performs second control for driving the motor 22 so as to reduce the rotational speed of the motor 22 down to the target value (N1) and maintain the rotational speed at the target value.
