Abstract

A feedpump for discharging a string of a viscous medium containing solid particles. The feedpump includes a casing and two gearwheels drivable to execute an oppositely directed rotation and arranged in the casing so as in each case to form and maintain gaps relative to both walls of the casing and to one another. The gaps have a size adapted to the size of the particles in the viscous medium.
