Claim:
1. A pump system comprising a pump assembly including a submersible pump arranged below a surface and a control device which is spatially separated from the pump assembly and arranged outside on the surface, wherein the pump assembly comprises at least one electrical supply lead connected to a frequency converter arranged outside on the surface, the frequency converter outputting the power supply to the submersible pump, wherein the pump assembly and the control device comprise communication modules, the modules being in communicating connection with one another for continuous data transmission of a digital data transmission signal via the supply lead, the digital data transmission signal including condition data acquired by the pump assembly for transmission to the control device, and the modules being designed in a manner such that an evaluation of a digital data transmission signal received by one of the communication modules is only effected in low-disturbance regions of a carrier signal formed by a supply voltage such that disturbances in the carrier signal whose temporal duration is smaller than a temporal duration of a smallest information unit to be transmitted in a course of data transmission of the digital data transmission signal are ignored during the evaluation, wherein the digital data transmission signal is modulated upon the carrier signal, and wherein the evaluation of the digital data transmission signal is deferred in moments of switching on and off of power switches of the frequency converter and the continuous data transmission is effected regardless of disturbances in the carrier signal caused by the switching on and off of power switches of the frequency converter.
