  We have established a semiclassical kinetic approach for various spin
correlated pumping phenomena incorporating spin rotation in wave functions into
transport equations. We employ this technique to study topological pumps and
illustrate spin pumping in a few models where various spin configurations or
topological motors drive adiabatic pumps. In the Rashba model we find that a
topological spin pump is driven by a meron with positive one half skyrmion
charge, the size of which can be controlled by external gates or Zeeman fields.
In the Dresselhaus model on the other hand, electron spins are pumped out by a
negative meron. We examine effects of Zeeman fields on topological spin pumping
and responses of fermi seas in various pumps. The phenomena of topological
pumping are attributed to topological Stern-Gerlach splitting and occur in a
transverse direction along which charge pumping currents either vanish or are
negligible. The transport equations established here might also be applied for
the studies of anomalous Hall effect and spin Hall effect as demonstrated in
one of appendices.
