A system for conveying pasty material through a conduit has an eccentric screw pump having a stator, a rotor that rotates in the stator, a housing with an intake port, and an output port connected to the conduit. A drive rotates the rotor and thereby draws the pasty material in through the intake port and expels the drawn-in material as a compressed-material strand into the conduit. A valve supplies gas pulses to the conduit at time intervals for separating the compressed-material strand into material plugs of limited length traveling through the conduit.
