A seal assembly for a compressor includes a static member fixedly dispose d within a compressor casing and having an end surface and a rotatable separ ator coupled with a compressor shaft and spaced from the static member. The separator has an axial end with a radial end surface located adjacent to the static member end surface such that a clearance space is defined therebetwe en. The separator has a plurality of openings extending inwardly from the en d surface and spaced about the shaft axis such that land surface sections ar e defined on the end surface. The land surface sections or/and the openings are configured to prevent fluid flow radially inwardly through the clearance space. The static member has two annular walls receiving an end portion of the separator, with annular ridges providing labyrinth seals disposed agains t inner and outer surfaces of the separator, and an annular deflector with a n angled deflector surface.
