A compression pump for an engine is provided. The pump may include a first pump impeller operatively coupled to a main shaft of the engine, a first inlet configured to at least partially receive bypass airflow, and a first outlet configured to direct compressed air to a thermal management system. The first pump impeller may be rotatably fixed about a common axis of the compression pump. Additionally the compression pump may extend radially to one exterior side of the engine. Furthermore the compression pump can be coupled to the main shaft of the engine by an engine towershaft. A first intake manifold may be coupled to a first inlet of the compression pump and a first discharge manifold may be couple to a first outlet of the compression pump which may have one or more heat exchangers.
