Abstract

The invention relates to an orbital pump for pumping a fluid, wherein the pump comprises at least one pump control system, a motor that can be controlled by the pump control system, a rotor shaft (10) for fluid transport, and a rotor sensor for detecting an absolute angle of rotation of the rotor shaft (40), the rotor sensor is connected to the pump control system and designed to transmit the angle of rotation of the rotor shaft (40) to the pump control system, and the pump control system is designed to rotationally control the rotor shaft (40) by means of the motor until the rotor shaft (40) is in a pre-determined angle of rotation position.
