Installation types
The FKV and FKC pumps are designed for two installation types:
• submerged installation on auto-coupling,
• free-standing submerged installation on ring stand.
Before installation, check that the bottom of the tank is flat and uniform.
Check that pit, pool or tank are well dimensioned and that water level assures a correct
running of electric pump with limited startings per hour.
5.1 Submerged installation on an automatic coupling device
Pumps for permanent installation can be installed on a stationary auto-coupling guide rail system. The auto-
coupling system facilitates maintenance and service as the pump can easily be lifted out of the tank.
In the case of a potentially explosive atmosphere, before starting installation operations, check
that the pump is suited for working in that atmosphere.
Make sure that the piping is correctly installed so that the pump does not have to bear loads
due to the weight of the pipes.
Do not use elastic elements or bellows in the pipework; these elements should never be used
as a means to align the pipework.
1 - Electric submersible pump
2 - Lifting chain
3 - Floating switch / probes
4 - Electric cable
5 - Electric panel
6 - Non return valve
7 - Gate valve
8 - Pit
9 - Supplementary pit with grid (optional)
10 - Delivery pipe
11 - Decantation area
12 - Foot pedestal
Proceed as follows:
-
Fix the upper bracket for the guide pipes (fig. 5 – pos.
A ) to the edge of the pit.
- Locate at bottom of pit the foot pedestal for the
automatic coupling (fig. 5 – pos. B) and check that the
guide pipe conical fixations are perfectly perpendicolar
and leveled to the correspondent fixations of the upper
bracket located to the edge of the pit.
-
Mark the position of the slots in the support foot, then
measure the exact length of the guiding pipes (fig. 5 -
pos. C).
- Fix firmly the pedestal foot to the bottom of pit with
suitable anchor clamps or metallic blocks.
-
Connect the delivery pipe to the foot pedestal outlet.
-
Disassemble the upper brackets from the edge of the
pit and insert in the conical fixations of the foot
pedestal the guide pipes previously cutted of correct
length and fix them to the brackets reassembling the
same to the edge of the pit.
