A moineau pump assembly includes a stator with a rotor extending through the stator, the rotor and stator sealingly engaging each other at spaced intervals to form a series of annular spaces. An upstream primary inlet is provided for fluids to enter a first of the series of annular spaces, while a drive unit rotates the rotor. As the rotor rotates, fluids are drawn through the upstream primary inlet and the series of annular spaces between the rotor and the stator. A portion of the rotor comprises a central flow passage extending from a downstream secondary inlet spaced downstream from the upstream primary inlet to the upstream primary inlet. A portion of the fluids being pumped are diverted into the downstream secondary inlet and pumped under pressure through the central flow passage of the rotor to the upstream primary inlet, thereby washing accumulated solids from the upstream primary inlet.
