Abstract: A pumping system includes a conduit that fluidly couples a pump outlet to a flush inlet to provide a path for liquid that exits the pump at the at outlet to be introduced into the chamber that housings a sliding seal via the flush inlet. A vaporizing heat exchanger is disposed along the conduit between the pump outlet and the flush inlet such that a cooling portion of the liquid that exits the pump is diverted from the conduit and the cooling portion of the liquid is used to cool fluid remaining in the conduit before it enters the flush inlet.
