surfaces of the shaft with solvent. Check to
ensure the shaft is free from contaminants,
nicks and burrs, or any sharp edges. If
necessary remove them.
b) Remove the screws [6570.2] from the pot and
remove the adjusting nut [2909].
c) Remove the key [6700.1] from the pump shaft.
d) Apply a thin film of mineral oil to the shaft
exposed area and the pot mounting surface.
e) Rest the pot assembly in the pump taking
special care not to damage the pump shaft, the
Lifeseal™ [4330.1] and the Bearing Gard™
[4330.2] during the pot installation and to
properly match the pump and pot alignment
fits.
f) Rotate the pot assembly on its receiving
surface to match up the holding holes.
g) Install the key [6700.1]. The keyway position is
reached by turning the centering sleeve [2470].
h) Re-install the pot holding bolts.
i)
Re-install the adjusting nut [2909].
j) Regulate the pump rotor axial play by turning
the adjusting nut [2909] as necessary.
k) Re-install the screws [6570.2].
l)
Tighten the Lifeseal™ [4330.1] rotary unit set
screws and remove the setting clips and bolts.
(See section 4.3.2, Lifeseal™ installation.)
m) Re-install the items removed from the
discharge head and the pot piping extension.
Use Heldite or similar proprietary pipe thread
sealant to seal the piping extensions, where
customer practices permit PTFE based pipe
sealants or PTFE tape these can also be
utilized..
n) Fill the pot with lubricant up to the required
level.
For 7000s and 7000s + 6000s series
the oil level is the centre of the oil level sight
glass; for 29000s + 22000s series the oil level
is indicated in the sectional drawing.
o) Check the oil level before operation. Also,
when specified, check that the piping system is
ready to provide proper cooling to the pot
4.5 Pump vertical axial play
adjustment
The pump vertical axial play adjustment depends
on the length of the shaft, which, in turn, depends
on the axial hydraulic thrust or force that tends to
elongate the shaft. It is also dependent on the
shaft diameter. The adjustment figure is indicated
in the pump User Instruction manual.
Adjustment is performed, once the pump and motor
are completely installed, by tightening or loosening
the adjusting nuts [2909] of the thrust bearing pot.
Further adjustment details are provided in the
pump User Instruction manual. Also refer to the
lubrication table in section 5.1.
4.6 Lubrication and cooling
requirements
Refer to the lubrication chart in section 5.2.
4.7 Motor stand and flexible coupling
After the thrust pot installation, install the motor
stand, the flexible coupling and the driver.
5 COMMISSIONING, START-UP,
OPERATION AND SHUTDOWN
These operations must be carried
out by fully qualified personnel.
5.1 Pre-commissioning procedure
5.1.1
Lubrication
Determine the mode of lubrication of the unit, eg
grease, oil, product lubrication etc.
For oil lubricated units, fill the bearing
housing with correct grade of oil to the correct level, ie
sight glass or
constant level oiler bottle.
When fitted with a constant level oiler, the bearing
housing should be filled by unscrewing or hinging
back the transparent bottle and filling the bottle with
oil.
