WebThe RWCU pumps provide the needed motive force to overcome piping and equipment pressure drops and sends the treated water back to the reactor vessel via the feedwater system. The RWCU pumps are motor driven, horizontally mounted, centrifugal pumps with an externally supplied mechanical seal. One pump provides 100% system flow WebThis model contains two pumps, one for the condenser and the feedwater pump. The condenser’s pump drives the flow from the condenser to the deaerator through two low-pressure heaters. The function of the deaerator is to remove the dissolved oxygen in the ratio of the steam on the surface of the liquid using Dalton’s partial pressure laws.
