A pump / flow guide is positioned in a gas turbine engine and attached to a transition duct to face a turbine disk. The pump / flow guide provides a smooth path for guiding purge flow to resist the ingestion of hot gas. One leg of the pump / flow guide extends radially outwardly and contacts the radially inner section of the transition duct that forms a “fish mouth.” Spaced tabs on the pump / flow guide receive bolts to secure the pump / flow guide to the transition duct. The pump / flow guide thus provides a relatively smooth flow passage for purge gas flow.
