Abstract
Various systems are provided for a seal chamber of a centrifugal pump. In one example, a seal chamber housing for a centrifugal pump includes a central cavity internal to the seal chamber housing, the central cavity having a greater diameter at a first end of the seal chamber housing and a smaller diameter at a second end of the seal chamber housing, and at least one flushing passage at the second end of the seal chamber housing. The at least one flushing passage is configured to directly fluidically couple the central cavity to an exterior of the seal chamber housing. In this way, increased cooling and debris removal may be provided to a seal positioned within the seal chamber housing.
