  We study adiabatic pumping at a normal metal/class-D superconductor hybrid
interface when superconductivity is induced through the proximity effect in a
spin-orbit coupled nanowire in the presence of a tilted Zeeman field. When the
induced order parameter in the nanowire is non-uniform, the phase diagram has
isolated trivial regions surrounded by topological ones. We show that in this
case the pumped charge is quantized in units of the elementary charge $e$ and
has a topological nature.
