A compressor diaphragm assembly for combustion turbines includes a plurality of vane airfoils, each of which is formed with an integral inner shroud. A segmented seal carrier is suspended from the inner shrouds, and an outer ring supports the plurality of vane airfoils from a casing portion of the turbine in a parallel relationship at a predetermined angle with respect to the longitudinal axis of the turbine. The outer ring has one or more grooves formed at the predetermined angle to engagably receive respective rows of the vane airfoils at their outer portion. Each seal carrier segment includes a pair of disc-engaging seals, and is formed to be engaged with the inner shrouds of one or more vane airfoils, in order to provide a labyrinth seal with discs assembled to form a rotating shaft.
