11. A scavenge pump assembly for an aircraft engine, comprising:
a scavenge pump housing;
a scavenge pump disposed inside the scavenge pump housing; and
a manifold adapted to flow a fluid containing a mixture of air and oil to the scavenge pump, the manifold including a manifold inlet, a manifold outlet fluidly connected to the scavenge pump, and a fluid passage extending between the manifold inlet and the manifold outlet, the fluid passage including a first bend and a second bend, the first bend being upstream from the second bend, the first bend including an oil isolator and the second bend including an air offtake, the oil isolator separating an oil fraction from the fluid at the first bend and directing the oil fraction to the scavenge pump, the air offtake separating an air fraction from the fluid at the second bend and directing the air fraction away from the scavenge pump.
