The phase diagram of the superfluid phase coupled to spin singlet ($S = 0$), and isospin triplet ($T = 1$) in infinite nuclear matter is analyzed within the non-relativistic Skyrme model. We use an approach that allows a unified and consistent treatment of the particle-hole and particle-particle channels. The gap equation is solved for the full range of accessible densities, isospin asymmetries and temperatures. The characteristic features of each of the components $T_z = 0,, pm 1$ are emphasized. The search of signatures of a BCS-BEC crossover yields negative results within the scheme proposed.
