摘要： A novel pump apparatus and method, the pump including a magnetically suspended and rotated impellor inside the pump housing. A novel sensor system detects the position of the impellor and thus provides the necessary information for operation of a suspension circuit for magnetically suspending the impellor. A valve member may be included as part of the impellor to prevent reverse flow in the event of impellor failure when used as a ventricular assist device.

摘要： The pump has a rotor (1) including conveying elements (3, 4), which partially convey fluid along axial direction of the rotor. The conveying elements or two groups of conveying elements partly convey the fluid in directions (12, 13, 17, 18), where the directions lie opposite to each other. Fluid streams are separated from each other before contacting the conveying elements, where the fluid streams are joined after passing through the conveying elements. The conveying elements are arranged in different sections of the rotor.
