Floating sucking-out system for fluids from circular cross sections, particularly for sucking oil from contaminated soil via boreholes

摘要

The sucking-out system is on the compression side of a centrifugal pump which may be outside the borehole. The mixture of driving fluid and conveying fluid is forced upwards and filtered in a container. The driving fluid is sucked through the pump to a sucking-out device. A diverting roller is fitted to reduce the volume of the floating body, so that a counterweight can be fitted. The sucking-out device is in the form of a jet pump.
