The invention relates to a rotary piston pump, in particular for pumping blood, comprising a piston rotor (1) which has particularly two or three faces when seen in cross-section, which is mounted in a piston chamber (2) and eccentrically rotates, the piston rotor (1) having in its interior a plurality of magnetically interacting elements (4, 4a, 4b), in particular permanent magnets and/or coils, and being driven by the magnetic interaction of these elements (4, 4a, 4b) with at least one moving magnetic field.
