A rotatably driven, hydrodynamic, centrifugal coaxial discharge pumping apparatus for moving fluids or flows of sludge or streams with trash or solids mixed therein with a single suction, diffusion casing pump. The pump has a vertical housing with an axial fluid flow upwardly through the housing. The pump is designed to operate with a submerged inlet having non-clog and other features that are especially useful for pumping fluids flowing in sanitary and storm sewer lines, for example.
