An adaptive eccentric screw pump, which enables, if necessary, an increase of the output, the pressure and/or the simultaneous output of more than one output medium, and wherein the eccentric screw pump has comparably low energy consumption and the production and maintenance expenditure thereof is kept low. For this purpose, the eccentric screw pump is equipped with a modular output system, including at least two output modules having in each case one rotor and one stator, wherein the output modules are coupled to one another and merely one actuation unit is associated with the output system, and wherein the output system for an output medium has more than one inlet and/or outlet or at least one modular perfusion housing.
