Abstract (en)

[origin: EP1777414A1] The magnetic pump drive has a motor-driven driver (10) surrounding a rotor (8) each fitted with opposing magnets (12). A fluid medium such as a heat-conductive oil, fills out the interspace between the outer pot (15) and inner pot (11) surrounding the rotor. The interspace is sealed from the pump delivery medium. The outer pot and inner pot contact one another at least in the area of the cylindrical sleeve faces and a network path (17) forming the interspace is let into the contacting faces inside the contact zone.
