If it is a gear pump it's easy. The gears carry fluid around the outside,
and it gets squeezed as the teeth mesh. So the flow is in the direction
that the outside of the gears move. Iny mo questions?

Let go a little farther with this. The fluid flow in a pump ALWAYS takes
the longest path through the pump from entrance to exit. Hence the oil in a
gear pump travels around the outside of the gears, Someone please give me
an example of a pump where this is not true.
