PUMPING DEVICE, DISPOSABLE DEVICE AND METHOD FOR OPERATING PUMPING DEVICE

The present invention provides a pumping device for transmitting liquid. The pumping device includes a single-use device and a reusable device. The single-use device is to be inserted into the reusable device and includes two pump units in series, one behind the other. Each pump unit includes a rotor for a bearingless motor, and can be magnetically levitated and driven without contact for rotation about an axial direction. The reusable device includes a stator for each rotor which form an electromagnetic rotary drive for rotating the rotor about the axial direction. Each stator is a bearing and drive stator with which the rotor can be magnetically driven and levitated without contact with respect to the stator. An independent control device is provided for each stator, and can independently activate a respective stator. 提出了一种用于输送流体的泵送装置，具有一次性使用装置和可重复使用装置，其中，一次性使用装置被设计成插入到可重复使用装置中，并且包括串联布置的两个泵单元，其中，每个泵单元包括用于输送流体的转子，其中，每个转子被设计为无轴承电机的转子，并且可无接触地磁性悬浮，并且可无接触地驱动，用于围绕轴向方向旋转，其中，可重复使用装置被设计用于插入一次性使用装置，并且对于每个转子包括定子，定子与转子
