10.0 Rotor assembly
10.1 Impellers, spacer are assembled on the shaft with a push to light press fit requiring
little or no heat
10.2 Impellers, spacers are held together axially by a conventional locknut assembly
10.3 All impellers are keyed to shaft using a staggered key arrangement.
10.4 The impeller hub is fitted with a shrunk to pre-stress the bore and minimize rubbing.
This also eliminates the relative thermal expansion and contraction since hubs and
shaft are manufactured with different materials.
10.5 The rotor assembly is dynamically balanced on a computerized balancing machine
11.0 Lubrication system
11.1 The bearing housings are grease lubricated (see detailed description in installation,
use & maintenance manual).
