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.

A seal chamber housing for a centrifugal pump, comprising:
- 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 configured to directly fluidically couple the central cavity to an exterior of the seal chamber housing.
A system for a seal chamber of a centrifugal pump, comprising:
- a seal chamber housing including a central cavity extending from a first end of the seal chamber housing to a second end of the seal chamber housing, the central cavity defined by an inner surface having a greater inner diameter at the first end and a smaller inner diameter at the second end, and at least one flushing passage in an external surface of the second end of the seal chamber housing;
- a seal plate in face-sharing contact with the external surface of the second end of the seal chamber housing;
- and
- a bottom surface of an impeller of the centrifugal pump.
A method for a centrifugal pump, comprising:
- suctioning coolant into the centrifugal pump by rotating an impeller housed within a casing of the centrifugal pump;
- flowing the coolant into a seal chamber of the centrifugal pump;
- circulating the coolant around a seal interface positioned within the seal chamber;
- and
- flowing the coolant out of the seal chamber via one or more flushing ports.
