A positive displacement pump for slurry incorporating particulate solids in suspension to provide an initial inlet port opening clearance corresponding to the exposed area of overlap between the port and each corresponding cylinder opening sufficient to permit substantially uninterrupted passage of particulate solids at the commencement of each suction cycle, the cylinder openings and following the initial overlap the total cross-sectional flow area exposed to each of the ports is generally constant irrespective of the rotational position of the barrel within the housing such that a constant volummetric flow rate of the driving fluid tends to effect a corresponding substantially constant volummetric flow rate of the fluid to be pumped.
