VORRICHTUNG ZUM ANFAHREN EINER NICHT SELBSTAENDIG ANSAUGENDEN KREISELPUMPE

摘要

Arrangement for facilitating the start-up of not self-priming centrifugal pumps for the pumping of radioactive liquids in a nuclear fuel reprocessing plant wherein radioactive liquid is pumped from a first to a second container through the container's top by means of transfer piping which includes a centrifugal pump having its suction side in communication with one container and its discharge side connected to a supply pipe leading to the other container. The supply pipe includes a pressurized air operated jet pump adapted to lift, during start-up, liquid from the container into the centrifugal pump which is then operated to pump the liquid from the one container to the other through the jet pump.
