Abstract

319,020. International General Electric Co., Inc., (Assignees of Allgemeine Elektricitõts-Ges.). Sept. 14, 1928, [Convention date]. Leakage-preventing devices; balancing moving parts. - A centrifugal pump with fluid admission on one side only of the impeller a, has an equalizing chamber b at the back of the impeller. To prevent air from penetrating the stuffing-box an auxiliary chamber e is provided adjacent the impeller hub and is provided with pressure fluid from the pump delivery i through the pipe h. Labyrinth packing f is provided at the side of the chamber c. The stuffing-box is in the form of a water-lubricated bearing, which receives water from the pump delivery through a pipe l. This water is discharged through a pipe m into the equalizing chamber b. A variable gap d connects the chamber b to a space g connected to the suction side of the pump.
