A pump cylinder in which a pump plunger is guided which divides the cylinder into a forward and a rearward subspace, which, in the forward subspace, has a connection for taking in the fluid medium to be delivered, the rearward subspace of the pump cylinder containing one or several electrochemical gas consumption cells for a consumption gas, an electric circuit being provided which is constantly or temporarily connected with the electrodes of the gas consumption cell, is characterized in that the rearward part of the pump cylinder is filled with an electrochemical consumption gas, and the electric circuit is designed for causing a gas consumption current so that the pump cylinder forms a device for implementing a process for collecting pasty masses, liquids, gases and mobile objects for a previously determinable time period.
