• 1 - PUMP ASSEMBLY IN THE WELL -
Before assembly, make sure:
– The real diameter and depth dimensions of the well are suitable.
– There is a minimum distance of 2 mtrs. between the pump ends and the well
bottom in order to avoid any mud infiltrations in the pump.
– There are the necessary hoists.
– The vertical delivery pipeline can bear the weight of the set.
– In the pump-pipeline connection, if the flange is required, there are very sturdy
bolts, type min. 8.8 .
– It is arranged with a rigid support made of stainless steel or cement to fasten the
pump pipeline-set.
Once the above mentioned conditions are arranged, hoist the set and place it vertically
in the well; put its end on the support with a suitable support equipment (if requested,
it can be supplied together with the pump) see Figure 13 .
DANGER! For pump lifting and handling, tight the set safely. Connection between
power supply cable and motor must be performed by a skilled electrician (for
connection and type of cable see elecrical system pg. 12).
ATTENTION! Avoid using joints with taping or unsuitable connections as they
can cause damages to the motor.
Couple the various pipelines through flanged or threaded ends and place them in
the well; if they are flanged, tight the bolts with the respective necessary load torque.
Fasten the electric power supply cable every 3 mtrs. of pipe by means of clips.
When the set has been installed at the right depth, fasten everything to the main
support through the bolts (lock the bolts using a dynamometric key).
ATTENTION! All these operations have to comply with the safety normes in
force.
In order to avoid that the minimum dynamic level sinks more than 1 meter above the
delivery of the pump, it is necessary to provide with the application of level electrodes.
ATTENTION! In case water sinks at the suction port level because of a too
much high capacity value of the pump or due to the seasonal lowering of the
water beds, there can be motor overheatings or the seizure of bronze bushing for
lack of lubrication.
After the connection, check again the insulation degree of the cable to make sure
it has not been damaged during the assembly.
Electrical insulation has to comply with electrical regulations in force.
• 2 - HORIZONTAL INSTALLATION IN THE TANK -
It is advised to use a shrouded electropump to obtain a water
flow on the motor and a suitable cooling.
In this case, when the electropump is supplied, it is already
equipped with the shroud and with 2 fastening supports to
the concrete floor of the tank bottom.
The tank has to be either open top or equipped as to place
the set trough a lifting equipment (see weights on the crates).
This has to be fixed to the floor through fastening
anchorsuitable for the hole type of the shroud support (use
GM Fischer type reinforcements or equivalent).
The pipeline shall be connected to the shroud through the
bolts.
ATTENTION! The electric system supplier has to follow the
safety instructions to keep the pump ever sunk in the water.
DANGER of pump failure and motor overheating.
