From the drawing for permanent installation of the submersible pump, the anchoring base of the pumps will be
placed on a foundation of concrete of suitable dimensions.
Check that the distance from the suction of the pump to the floor is the one shown in the drawing not to obs-
truct the fluid entrance into the pump.
Once the anchoring base is placed, fill the font-cases of the anchor bolts, wait for the drying of the concrete
and verify the leveling of the discharge flange of the anchoring base.
3.2 ALIGNMENT OF THE SLIDING GUIDE PIPES
Once the anchoring base is on the foundation, we must check the alignment of the guiding pipes as per fo-
llowing instructions:
•
The guiding pipes must go perfectly perpendicular and placed between the top bolts, independent and
supplied with the anchoring base and the low bolts of the anchoring base.
•
The top bolts must be installed in the upperr side of the pumping well and properly aligned.
•
To make this alignment we can use a plummet to match the center of the top and low bolts.
•
Check raising and lowering the pump, that it slides correcty.

3.3 DISCHARGE PIPES
They must be installed according to the following drawing:
The discharge pipe must have a check valve installed in order to absorb the water hammer that could be produ-
ced and to avoid the return of the suction fluid, which can cause serious problems.
If there are high points in the discharge pipe, it is necessary to install in those ones a few air valves (air purgers),
to eliminate the air pockets that can appear.
The discharge pipes must be supported by external supports to avoid their weight gravitating on the flanges of
the anchoring base
The discharge pipe must be perfectly aligned up with the anchoring base to avoid efforts on them.
As guiding information, we give the average of the admissible efforts in the flanges of the pumps.
