ABSTRACT:
Disclosed is a permanent magnet pump in which the pump impeller and the interior rotor of a permanent magnet driving means receives drive torque transmitted in synchronism by an exterior rotor. The exterior rotor is positioned, axially in one form and radially in another form, opposite the interior rotor with an air gap defined between them. Thin, plate-like permanent magnets carried by the rotors face each other across the air gap. The pump impeller shaft and the interior rotor are housed and supported in a common space which is sealed from the exterior by a partition of non-magnetizable material extending through the air gap.
