Beschreibung
Zusammenfassung:	An intake nozzle for the inlet pipe of a pump has a vertical duct with a downwardly facing mouth and a surrounding disk shaped intake portion with a bottom surface which faces a flat surface such as a floor or tank bottom to take liquid from the floor down to a shallow depth. The bottom surface is shaped with a flat outer part and an upwardly and inwardly curved inner part converging to the mouth. The surface is shaped and spaced from the flat surface with annular areas defined therebetween so that the liquid enters the peripheral edge slowly and accelerates up to an inner edge of the flat portion and then remains at constant velocity from the inner edge of the flat portion through the mouth and the pipe to the intake of the pump.
