Abstract

Apparatus for collecting polluted liquids such as oil on water includes a first pumping stage consisting of a rotatable annular rotor having curved blades shaped to draw liquid inwardly towards the centre of rotation. Stationary blades are positioned within the rotor blades to receive liquid into the spacers between them. A further pumping stage has rotatable blades shaped to accept the liquid from the stationary blades and deliver it under pressure in an upward direction to an outlet. The pumping apparatus is preferably mounted on a flotation unit which is suitable for collection of oil from the surface of the water.
