2.5 Position the CPM PX with the gland tight against the seal chamber
face. Turn the gland so that the flush tap is as close to the 12:00
o’clock position as possible and so that the flush piping will clear the
bearing frame. Tighten the gland nuts evenly in a diagonal
sequence. Do not overtighten the gland nuts, as this can warp seal
parts and cause leakage.
2.6 Assemble the pump. Avoid
pipe strain. Align coupling
properly.
2.7 With the impeller, shaft,
coupling, and bearings in
their final operating positions,
tighten the CPM PX drive
collar set screws.
See Figure 5.
