  We theoretically investigate the phenomena of adiabatic quantum charge
pumping through a normal-insulator-superconductor-insulator-normal (NISIN)
setup of silicene within the scattering matrix formalism. Assuming thin barrier
limit, we consider the strength of the two barriers ($\chi_{1}$ and $\chi_{2}$)
as the two pumping parameters in the adiabatic regime. Within this geometry, we
obtain crossed Andreev reflection (CAR) with probability unity in the
$\chi_{1}$-$\chi_{2}$ plane without concomitant transmission or elastic
cotunneling (CT). Tunability of the band gap at the Dirac point by applying an
external electric field perpendicular to the silicene sheet and variation of
the chemical potential at the normal silicene region, open up the possibility
of achieving perfect either CAR or transmission process through our setup. This
resonant behavior is periodic with the barrier strengths. We analyze the
behavior of the pumped charge through the NISIN structure as a function of the
pumping strength and angles of the incident electrons. We show that large
($Q\sim2e$) pumped charge can be obtained through our geometry when the pumping
contour encloses either the CAR or transmission resonance in the pumping
parameter space. We discuss possible experimental feasibility of our
theoretical predictions.
