Submerged Installation On An Automatic Coupling Device - DAB FK Série Instructions Pour L'installation Et La Maintenance

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.

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
-
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.
Assemble the special skid-flange (fig. 5 – pos. D) on the delivery
-
outlet of the pump and hook the rope or chain to the handle or slot
located on the upper part of it.
Lift the electric pump up to over the pit and let it slowly descend guiding
