6. INSTALLATION

6.1. Dimensions
For the dimensions of the device refer to the annex
"Dimensions" (paragraph 12.1 Annexes).
6.2. Ambient requirements and installation site
dimensions
The customer has to prepare the installation site in
order to guarantee the right installation and in order
to fulfill the device requirements (electrical supply,
etc...).
It's Absolutely forbidden to install the machine in an
environment with potentially explosive atmosphere.
6.3. Unpacking
Inspect the device in order to check any
i
damages which may have occurred during
transportation.
Package material, once removed, must be discarded/
recycled according to local laws of the destination
country.
6.4. Installation
Along its entire length the well diameter must be
wide enough to allow for passage of the pump with
clearance all round.
6.4.1. Pipes
When threaded connections are used, delivery pipes
must be tightened to avoid any risk of the pump

falling into the well owing to unscrews.
It is advisable to connect the metal pipes to the
threaded joints with spot welding.
With plastic pipes use proper connections.
The SD, 6SDX-series pumps have two holes in the
delivery casing for anchoring and for raising the
pump.
A safety rope or chain of non-perishable material
should always be used to secure the pump.
Attach the power supply cables to the delivery pipe
with cable clamps placed at intervals of approx 3 m.
Lower the pump into the well, making sure the feed
cables are not damaged in any way during the
operation.
Never use the electric power cable to
suspend the pump.
When the pump is operating, the delivery connection
must be submersed at least 1 m below the deepest
dynamic level of the well; for this purpose, it is
advisable to install an automatic control system
which will stop operating of the pump when the level
of the water falls below this limit.
Position the pump at a distance from the bottom of
the well which will be sufficient to avoid accumulation
of sand or mud around the motor and to eliminate the
risk of overheating.

6.4.2. Delivery pipe
The following components must be installed in the
delivery pipe:
• a pressure gauge;
• a check valve at max. 7 m from the pump outlet and
more lift-type check valves (5), depending on the
type of installation (at least one every 50 m in the
straight vertical pipe above the pump), to provide
protection against water hammering;
• a gate valve to regulate delivery, head and
absorbed power.
