ABSTRACT:
A magnetic pump drive comprises an isolating shell which is structured in the form of a stepped cylinder having at least one step for creating at least two cylindrical sections of different diameters. The efficiency of the power transmission of a driver carrying permanent magnets through the isolating shell onto a rotor also carrying permanent magnets is maintained in comparison with the efficiency of known devices, but the strength and form stability of the isolating shell is drastically improved. The strength against high system pressures is based on the steps which may comprise slipped-over rings or comprise integral reinforcement rings which act like barrel hoops.
