Abstract: A pump drive for an extracorporeal blood pumping system including an adjustable drive magnet. The pump drive may be coupled to a blood pump which includes a pump impeller. The pump drive may include a stepper motor for dynamically adjusting the position of the drive magnet. The position of the drive magnet may be varied to vary the distance between the drive magnet and an impeller magnet of the pump impeller. Adjusting the position of the drive magnet may include dynamically adjusting the drive magnet and may include axially moving the drive magnet to thereby vary a magnetic attraction force between the drive magnet and the impeller magnet which may thereby minimize forces acting on one or more bearings of a pump impeller.
