Abstract
A double acting metering pump is disclosed for use in apparatus to prepare matrices containing frangible particulate material. The double acting pump provides a metered output of matrix containing frangible particulate material which is mixed with a parent matrix from an extruding apparatus in a downstream static mixer. The pump includes pneumatically actuated valves that control the flow of matrix to each of two alternately discharged pumping chambers. The pump is facilely disassembled for cleaning and is surrounded by a heating jacket to maintain an essentially uniform temperature in the matrix during pumping.
