A pump for pumping large solid articles includes a rotary pump having a plain disc impeller (28) disposed in a substantially cylindrical chamber (26) of a housing (24) with an inlet (54) coaxial of the impeller into the housing and an outlet (56) from the periphery of the chamber with a rotor arranged to provide a substantially unobstructed passage between the inlet past the discs of the rotor to the outlet of the pump. The impeller includes pairs of discs (40, 42) spaced close together for providing increased fluid pressure and pairs spaced apart of distance for providing a passage for the solid articles. The articles are pumped in a fluid medium, such as water, through the pump and maintained suspended during transport from the inlet to the outlet of the system. |
