ABSTRACT:
A cone pump, fundamentally in design based on an Archimedes screw, comprising a tubular member having a helical screw mounted therein, integrally joined thereto, the flights of the screw being radially inclined to the longitudinal axis of the tube, the entire structure having a central longitudinal opening, the end discharge being characterized by a liquid seal, the structure being designed to have its lower or intake end immersed in liquid, and carrying solids such as watery sewage sludge, and, by rotation, to lift the sludge through elevations as high as 20 and 30 foot head (6 to 10 meters) through an angle of elevation of from 30.degree. to 50.degree., the preferred range being 36.degree. to 45.degree..
