Abstract:
A floating pump assembly comprising: a) a flotation assembly structured to float on a body of water, b) a pump housing including an inlet and an outlet and a fluid drive assembly disposed in fluid communication with said inlet and said outlet comprising an elongated drive shaft, said pump housing is mounted on said flotation assembly so as to be at least partially filled and submerged in water between said inlet and said outlet, and said pump housing and said fluid drive assembly are collectively oriented to at least partially define an axial flow pump, c) said fluid drive assembly structured to establish a path of fluid flow between said inlet and said outlet and being at least partially disposed coincident to a longitudinal axis of said pump housing, d) said pump housing supported on said flotation assembly and disposed to orient at least said outlet in a predetermined orientation which minimizes physical disorientation of said flotation assembly, e) said inlet and said outlet disposed in a submerged position during operative and inoperative periods of said fluid drive assembly, and a cage structure including a substantially open construction and disposed in spaced at least partially surrounding relation to said drive shaft.
