Abstract
A flow directing device is provided for a fluid filled seal chamber for a centrifugal fluid pump, wherein the pump includes a seal chamber housing, a rotary shaft extending through the housing, an impeller mounted on one end of the shaft, and a rotary seal mounted about the shaft. The rotary shaft and housing define the seal chamber opening toward the impeller. A plurality of angled vanes radially depend about a circumferential portion of the seal chamber to direct the flow of fluid in the seal chamber along the rotary shaft to remove suspended solids from the rotary seal when the vanes extend in one direction, and to remove vapor bubbles from adjacent the rotary seal when the vanes extend in another direction and are coupled with a bulkhead flange.
