INSTALLATION
Equipment operated in hazardous locations
must comply with the relevant explosion protection 
regulations. See section 1.6.4, Products used in 
potentially explosive atmospheres. 
 
4.1 Thrust bearing pot installation
Pots are either delivered to the customer fully 
assembled except for the oil/cooling piping 
extension, or pre-installed in the pump. 
 
Before installation remove all items from the pump 
discharge head. 
a) Remove any debris and thoroughly clean the 
surface receiving the pot with solvent. Apply a 
thin film of mineral oil to the surface. 
b) Remove the screws [6570.2] from the pot, the
adjusting nut [2909] and the oil flinger, oil 
thrower [2540]. 
c) Remove the key [6700.1] from the pump shaft.
Thoroughly clean, with solvent if necessary, the 
exposed surface of the shaft and apply a thin 
film of mineral oil to it. 
d) Install the pot and the rest of the assembly in
the pump. Take care not to damage the pump 
shaft during the pot installation and to properly 
match the alignment fits of the pump and pot. 
e) Rotate the pot assembly on its receiving
surface to match up the holding holes.
f) Install the key [6700.1]. The keyway position is
reached by turning the centering sleeve [2470].
g) Re-install the pot holding bolts. 
h) Re-install the oil flinger, oil thrower [2540]. 
i) 
Re-install the adjusting nut [2909].
j)
Regulate the pump rotor axial play by turning, 
as necessary, the adjusting nut [2909]. 
k) Re-install the screws [6570.2]. 
l) 
Re-install the items removed from the 
discharge head and the pot piping extensions. 
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. 
m) Fill the pot with lubricant up to the required
level. Open the vent plug [6521] while filling.
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. 
n) Check the oil level before operation. Also,
when specified, check that the piping system is 
ready to provide proper cooling to the pot. 
4.2 Optional Bearing Gard™
installation
 
4.2.1 
Preparation before installation
a) Remove the oil seal from the housing. 
b) Check to ensure the housing bore is free from 
contaminants, nicks and burrs or sharp edges.
c) Check the shaft and remove any burrs or sharp
edges on the shaft keyway and trademark 
stamps on the shaft. 
d) Thoroughly clean the shaft and housing bore. 
e) Concentricity of the housing bore to the shaft is 
to be maintained within 0.13 mm (0.005 in.) 
TIR. 
 
4.2.2 
Bearing Gard™ installation
a) Do not disassemble the Bearing Gard™
[4330.2]: it is designed to be installed as a unit.
b) Lubricate the O-rings, the shaft and housing
bore with the lubricant provided.
c) Align the Bearing Gard™ [4330.2] in the
housing so the drain slot is located on the 
bottom. 
d) Install the Bearing Gard™ [4330.2].
Original-style Bearing Gard™ and Metallic 
Bearing Gard™ ll. Use an arbour press to 
push on the outer portion of the stator. Do not 
use a hammer. 
Non-metallic Bearing Gard™ ll. Install using 
hand pressure only.
