  We present a proposal for an adiabatic quantum pump based on a graphene
monolayer patterned by electrostatic gates and operated in the low-energy Dirac
regime. The setup under investigation works in the presence of inhomogeneous
spin-orbit interactions of intrinsic- and Rashba-type and allows to generate
spin polarized coherent current. A local spin polarized current is induced by
the pumping mechanism assisted by the spin-double refraction phenomenon.
