1.

Assemble the casing (100), expeller (262) and hub disc
(184) using bolts (370J) prior to installation on the
bearing frame.

2.

Insert the shaft sleeve into the packed stuffing box so it
engages with the recess in the expeller. This will act as
a guide and center the expeller until the impeller can
be installed.

3.

Prior to sleeve installation on the shaft, apply a bead of
silastic or silicon sealant on the expeller hub faces to
seal the rotor assembly.

4.

Carefully slide the whole assembly on to the shaft
using the sleeve as a guide until the hub disc is aligned
with the fit and bolt holes in the bearing frame.

5.

Secure with bolts (370C).

6.

Install the impeller by turning it in the clockwise
direction taking care to tighten it against the expeller
and shaft sleeve prior to clearance adjustment. Apply
anti-seize or grease to threads of shaft to make future
removal easier.

7.

Replace the suction cover liner after applying a liberal
amount of anti-seize compound or grease on the outer
shoulder. This will also make removal easier in the
future.

8.

Install O-Ring (412F).0

9.

Replace suction end cover (182) with bolts (370E).
Only apply a moderate torque to tighten.

10. Check impeller clearance.

Lubrication

To lubricate the seals and purge the stuffing box, use a
general purpose waterproof grease. Several shots of grease
should be added to the stuffing box, as little as every three
operating days or as much as every four operating hours,
depending upon the severity of the pumpage abrasiveness.
In addition, grease should be added prior to every tenth
start-up.
