I did a study on how to work with dynamic meshes in OpenFOAM, in particular for its application to a gear pump simulation. I want to share my work with you, so that anyone that may find it helpful can access to it.

Gear Pump Animation

The work consists on meshing the geometry with snappyHexMesh in parallel and extruding it with extrudeMesh to make it two-dimensional. Then a custom boundary condition for the movement of the mesh is created. Finally the simulation is run in parallel, by generating an initial mesh, moving it as much as possible, up to acceptable limits of deformation, and finally replacing it with a new mesh. Everything is completely automated.
