A mixer assembly for mixing fluid material in the bore of a barrel wherein the mixer assembly includes structure for mixing and pumping toward its outlet end the material fed thereto comprising a stator assembly fixed in the barrel having outer cylindrical surface portions conforming substantially to the surface of the bore and having a stator bore provided with a groove-interrupted inner surface, and a driven rotor member having a groove-interrupted outer surface confronting the inner stator surface. The inner stator surface and outer rotor surface each have continuous helical grooves cut therein along a helical path which changes in depth with length from a small minimum depth to a larger maximum depth but never disappearing and having a plurality of axially spaced circumferential grooves at planes perpendicular to the bore center axis subdividing such surfaces into axially spaced serially arranged mixer sections with portions of the helical grooves extending between the circumferential grooves defining each section.
