Caution :
1. The pump bearings are not filled with oil.
2. The stuffing boxes are not packed.
All apertures are plugged with PVC stoppers.
7. Accessories
As a general rule, the following items are supplied loose with
the pump :
1 set of binding bolts (only supplied loose if the pump is supplied
without a baseplate).
1 set of foundation bolts (if the pump is supplied with a
baseplate).
On request, the following items can be supplied, amongst
others :
Pressure gauge holder or pressure gauge bridge
Pressure gauge
Pressure vacuum gauge
Stop valve for pressure gauge
Coupling extractor device
1 set of shims and packing plates for levelling up
1 wooden cutting jig for packing rings
1 set of special tools
8. Installing the Pumping Set
8.1 Description of Site prior to Commencement of
Erection
When our erection staff arrive on site, the pump foundation
must have been checked for dimensional conformity with our
foundation drawing data by the site management, and cleared
for erection to preceed. The foundation and its immediate
surroundings must be in a suitable condition to enable the
efficient and speedy erection of the pump and accessories to
proceed with out hindrance.
Our erection staff must be able to make use of customer’s
hoisting gear, e.g. the engine room crane etc. for transport
and erection if required.
Our erection staff will check the correct orientation of the
foundations in relation to the space axis after c;earamce fpr
erection has been given. The site management is responsible
for the zero point marking of the foundation (see ‘‘Conditions
of Erection’’).
The areas for the packing plates (shims) should now be marked
out and trued up in accordance with the foundation drawing.
Then thick packing plates should be laid in position and levelled
up with a spirit level.
The packing plates should lie flush on the foundation and be
levelled up as truly horizontal as possible to facilitate the
subsequent alignment and levelling up of the complete pumping
set as accurately as possible. The exact height is of less
importance at this stage, because any difference in heights
can be compensated by the insertion of shims of varying
thickness when the set itself is levelled up. Three point support
should be adopted for the preliminary levelling up.
Fig. 38 Preparation of foundation
8.2 Installation and preliminary Levelling Up
The pumping set should only be placed on the foundation after
the latter has set quite firmly, and the preparations for the
foundation described above should be carefully followed.
Before placing the set on the foundation, suspend the
foundation bolts in the baseplate. Then fix the longitudinal and
lateral directions and the correct height, then carry out a
preliminary levelling up with the aid of a spirit level, and grout
in the foundation bolts.
8.3 Aligning the Coupling
If the bare pump only is supplied, i.e. the motor or gearbox are
not mounted, the flexible coupling should be pre-heated to 100-
120
0
C approx. in an oil bath before mounting on the stub shafts.
The flexible elements should be removed beforehand.
Caution : Never drive the half coupling onto the shaft by
hammer blows. Always use a pusher device to mount it on the
shaft. (see Fig. 39).
In order to align the shafts, the pump and driver should be
pushed towards each other until the two coupling halves are
separated by the axial gap specified in the foundation or
installation drawing.
The preliminary alignment of the coupling is effected by means
of a short steel straight edge and feeler gauge.
