The local Seyfert 2 galaxy NGC5135, thanks to its almost face-on appearance,a bulge overdensity of stars, the presence of a large-scale bar, an AGN and aSupernova Remnant, is an excellent target to investigate the dynamics ofinflows, outflows, star formation and AGN feedback. Here we present areconstruction of the gas morphology and kinematics in the inner regions ofthis galaxy, based on the analysis of Atacama Large Millimeter Array (ALMA)archival data. To our purpose, we combine the available $\sim$100 pc resolutionALMA 1.3 and 0.45 mm observations of dust continuum emission, the spectroscopicmaps of two transitions of the CO molecule (tracer of molecular mass in starforming and nuclear regions), and of the CS molecule (tracer of the dense starforming regions) with the outcome of the SED decomposition. By applying the$^{\rm 3D}$BAROLO software (3D-Based Analysis of Rotating Object via LineObservations), we have been able to fit the galaxy rotation curvesreconstructing a 3D tilted-ring model of the disk. Most of the observedemitting features are described by our kinematic model. We also attempt aninterpretation for the emission in few regions that the axisymmetric modelfails to reproduce. The most relevant of these is a region at the northern edgeof the inner bar, where multiple velocity components overlap, as a possibleconsequence of the expansion of a super-bubble.
