Abstract: An apparatus for treating high-consistency fiber suspension is especially suitable for short distance conveyances of thick fiber suspensions (consistency more than 15%) in pulp and paper industry, for example for discharge of mass towers either with or without any actual pump. The treatment of fiber suspension with a consistency more than 15% is not possible with the known technique without a displacement type of pump, which is expensive and easy to break. Additionally, in discharging of the mass tower, drop leg, etc., fiber suspension causes trouble by arching in the container in such a way that it forms an open chamber around the pump located at the bottom of the container which chamber is slowly filled by fiber suspension. The problems are solved or minimized by arranging a feed apparatus in the pump chamber, which feed fiber suspension to a fluidizing rotor, for fluidizing the fiber suspension, whereafter the suspension flows onwards.
