ABSTRACT:
A pump for pumping fragile articles including fish and glasses without damage includes a rotary pump having a plain disc impeller disposed in a substantially cylindrical chamber of a housing with an inlet into, or coaxial of, the impeller into the housing and an outlet from the periphery of the chamber, with the rotor arranged to provide a substantially unobstructed passage between the inlet past the rotor to the outlet of the pump. The method includes pumping fragile articles in a fluid medium by means of a disc impeller pump having an unobstructed passageway between the inlet and outlet of the pump.
