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.

When performing a method for pneumatically conveying plastic pellets, the plastic pellets are conveyed, by means of a carrier gas, through a conveyor line from a feed point to a destination with a liquid being added thereto, wherein the quantity of liquid added to the plastic pellets and/or the carrier gas is such that during conveying, the carrier gas is oversaturated with the liquid at least in sections of the conveyor line in such a way that a Froude number defining the conveying conditions in the conveyor line is smaller than 45 at any point along the conveyor line.
