ABSTRACT A material transport system is disclosed which comprises, in combina- tion, means for effecting the controlled distribution of a particulate solid- liquid matrix, and means for urging the matrix by positive displacement through a constraining conduit so that no degradation of the particles of the matrix occurs during transit thereof. The said particles are sufficiently closely packed to ensure the movement of the particles by plug flow wherein the liquid is displaced towards the periphery of the conduit to constitute wall-slip fluid, whereby shear forces within the plug are absent. The means for urging the matrix is a pulse-free discharge positive displacement pump, the fluid sealing means for the pistons and valve plates thereof being also the source, at least in part, of the wall-slip fluid. An auger or screw feed delivers said matrix to the suction side of said pump. Water entry injectors feed the suction side of the pump with lubrication fluid.
