Abstract
A pump arrangement is disclosed including a magnetically drivable micropump for pumping a liquid pumping medium, a bearing carrier as a base part, and an outer magnet and an inner magnet which transmit a torque to the micropump via an axial shaft. Three radial bearing pieces for the rotational mounting (guidance) of the shaft and of the micropump are positioned and fixed in the bearing carrier. The micropump is held in an eccentric bearing by a cover arranged at an end. A duct structure for a forced flow is provided including at least one radial duct portion in the cover and an axial duct portion in the bearing carrier to flush and/or to lubricate the bearings actively with the pumping medium. One of the bearings is arranged closer to the inner magnet and/or another of the bearings is arranged closer to the micropump.
