ABSTRACT OF THE DISCLOSURE A screw extruder and positive displacement pump assembly for plasticating or melting solid plastic material or the like, including an extruder screw member in an elongated cylindrical barrel having an upstream end and a downstream or discharge end, the screw being rotatably housed in portions of the barrel adjacent the upstream end. The screw has a helical thread of plural turns integral with the core of the screw having a minimum clearance to the barrel for feeding the plastic material along the screw from its feed end to its discharge end. A positive dis- placement Moineau type pump is located in the barrel near the outlet end having a stator member and a rotor member rotatable therein coupled to and driven by the screw, the stator and rotor members having confronting surfaces of developed helical contours prividing helical threads of wide rounded form with a lesser number of threads on the rotor providing a series of pumping pockets which progress longitudinally through the pump section.
