6.9 Assembly
To assemble the pump consult the sectional
drawings.
Ensure threads, gasket and O-ring mating faces are
clean. Apply thread sealant to non-face sealing pipe
thread fittings.
After complete assembly with
headstock and bearing housing the rotor must be
lifted!, see section 5 .3 Impeller clearance
6.9.1 Assembly of radial flow impeller pump types
Assembly is done preferably in vertical position.
1) Put the last stage diffuser [1410.2] into the
discharge casing [1140]. Insert the O-ring
[4610.5]. Repeat this with all the stage casings
[1160], diffusers [1410.1] and O-rings [4610.5].
2) Put the discharge casing [1140] over the pump
shaft [2110].
3) Put in the key [6700.3] in the keyway and slip on
the interstage sleeve [2410.2], the last stage
impeller [2200.1] and the interstage sleeve
[2410.1] to the shaft.
4) Put on the next stage casing assembly. Put the
key [6700.3] in the keyway and slip on the
impeller [2200.1] and the interstage sleeve
[2410.1] to the shaft.
5) Repeat step 4 until you reach the first stage. After
slipping on the first stage impeller [2200.2] and
the interstage sleeve [2410.2] you can put on the
suction casing [1130].
6) Fix the hydraulic assembly by tightening the tie
bolts [6571].
This must be done croswise
with required torques.(refer to section 6,
Maintenance)
7) Put on the distance sleeve [2460], or inducer
[2215] and secure the assembly by tightening the
impeller nut [2912] just by hand.
8) Loose the impeller nut [2912] to the next location
for securing it with a grub screw [6814.2].
9) For further pump assembly follow reverse
disassembly procedure.
