摘要： A magnetically driven centrifugal pump includes a sealed housing enclosing a magnetically driven rotor on an axle of rotation contained within the housing, the axle being attached to the back inside wall of the housing and extending therefrom into the rotor, the rotor having impellers attached to the face thereof toward the front of the housing, the impellers defining radial fluid passages leading from the axial center of the front of the housing to the periphery of the housing and the rotor having radially oriented magnets in the back face thereof for coupling with similarly oriented magnets in an external magnetic drive, whereby the axial dimension of the rotor need be only the width of a radial magnet plus the axial projection of an impeller and the axial dimension of the sealed housing may be only slightly greater than the axial dimension of the rotor and may be substantially less than the radial diameter thereof. In operation, fluid enters an axial input port at the front of the housing and discharges from an output port at the periphery of the housing and the external magnetic drive magnetically couples with the rotor through the back wall of the housing. In a preferred embodiment, the impellers are radially extending ridges on the front face of the rotor and a disk-shaped plate attaches to and covers the impellers defining each radial passage between adjacent ridges, the face of the rotor and the covering plate.
