11.Fix the gasket on the bottom casing , mount the top casing , fit the casing steady
pin in that location. Top and bottom casing half‟s with help of casing joining bolts.
Check the pump hand free rotation.
12.Fix the gland packing and lantern rings. After that split gland to be fitted with
pump.
13.Connect the auxiliary piping and If bearing housing positioning bolts is available
in the pump the special care to be taken for adjusting the complete rotor set.
When mounting the impeller part No . 234, pay attention to the direction of rotation
of the entry of blade !! Shaft Sleeve part No . 524 With same position numbers in
sectional drawing both part No . 921 Sleeve nuts have right-hand thread With
different part numbers one impeller nut will be provided with left-hand and the other
with right- hand thread.
Note : The thread of the nut of the stationary bearing side has the same direction as
the direction of rotation of the shaft, when looking at the shaft against the drive side.
The impeller nuts should not be tightened now Push casing wear rings with keys
over impeller part No . 502 rings. Part No. 940.10 Push neck bush (optional) Part
No. 456
Mechanical Seal (See Seal drawing)
Sealing Cover : First of all, the sealing covers are completely pre-assembled. This
includes the installation of the cover neck bushes, the o-rings and the correct
mounting of the stationary seal ring. When mounting the stationary seal rings pay
attention to pins in the seal cover. If pins are incorporated, the stationary rings with
their grooves and bores must be pushed carefully over these pins.When screwing
on the covers make sure the leakage drain bores point downwards. Here too, the
sleeve nut (or the impeller nut) must not yet be tightened and secured.
Shaft Bearings : After complete assembly of the rotor and bearings this structural
unit will be inserted into the pump casing lower half (part 105.02), taking care that
the half collar of the neck bushes (part 456.02) is inserted in such a way that it is not
towering the gasket and that the fitting keys (part 940.10) are inserted in the
grooves in the pump casing lower part. Furthermore the half collars of the neck
bushes and the wear rings have to be pushed to the casing lower part up to solid
fitting. Subsequently, the complete rotor will be centered by means of adjusting
screws which are positioned at the casted on bearing lanterns of the casing lower
part, and secured with the nuts belonging to it. Now the bearing housings are bolted
to the pump lower half. Then adjust and secure the throwers (part 507).
