<p>This new invention, the water column floating pump, is a fluid pump (10) which uses a rotationally symmetric container (12) to pump fluid from an inlet reservoir (40) to the outlet end (16) of the rotationally symmetric container. The rotationally symmetric container is adapted to float with its axis of rotation (20) vertical in a pump flotation chamber. The rotationally symmetric container (12) floats and rotates in the fluid being pumped and uses the buoyancy of fluid to carry its weight. A plurality of helically spiralling conduits (30) proximate the periphery of the symmetric container (12) forms a system of vacuum suction tubes designed to suck water from the inlet reservoir (40), proximate the bottom of the fluid pump, to the outlet end (16) proximate the top of the container. The rotationally symmetric container (12) operates at low rotational speed and requires a small horsepower motor (60) to overcome water friction and water pressure.</p> |
