Abstract

1,036,407. Centrifugal pumps. JOSEPH LUCAS (INDUSTRIES) Ltd. Aug. 7, 1964 [Aug. 10, 1963], No. 31666/63. Heading F1C. The flow through the inlet 14 of a centrifugal pump is controlled by a manually-adjustable valve 16. When the valve is only partially open, all the liquid is directed by blading 27 in the impeller eye to auxiliary impeller blading 23 which delivers it to an auxiliary outlet 24. When the valve is opened further to provide a flow greater than can be handled by the auxiliary impeller blading, liquid flows over an annular partition 21, which conveniently extends radially inwardly beyond the shroud plate 26 to form a weir, and is delivered by main impeller blading 18 to a main outlet 19. The outlets 19, 24 may be connected to a common delivery conduit, flow from the outlet 19 to the outlet 24 or vice versa being prevented by non-return valves 20, 25.
