To connect the pump suction with the pipes, if it is diameter is bigger than mouth suction
diameter, you should use an eccentric coupling.
In suction installations (maximum 4 meters) you must take into account the curves,
besides installing a valve with strainer which must always be submerged and clean.
When the geodesic drive level is greater than 15 meters, a stopper valve between the
pump and the closing valve on the drive mouth must be inserted to protect the pump from
the "water hammer" effect.
Do not use the pump as a support for the pipes. Pipes have to be anchored on its own
support. Take into account the weight of the water filled pipes.
The position of connecting pipes must match perfectly without deviations and efforts with
the suction and discharge mouth of the pump. Thus avoiding that tensions may cause
pipes misalignments between the body and the motor shaft, reducing the life of the
mechanical seal and an also an unnecessary torque effort in the connecting screws of the
two scrolls and of these with the engine.
It is recomended to install elastic sleeves to absorb the vibrations
of the pump and the expansion of the pipes installation at the
suction and the discharge port of the pump.
During assembly check that the gaskets between the flanges do
not protrude into the pipes. Before connecting the pipes, be sure
they are internally clean.

5.3 electrical connection
- In general, the electrical installation has to be done in accordance with the
requirements of the regulations and complementary technical provisions that apply.
- It is necessary that the electrical installation and wiring the pump is checked by a
licensed electrician.
- The mains will have neutral and ground conductors. The grounding wire should be the
first to be connected, and the last to be disconnected.
- The supply voltage must correspond to that shown on the nameplate of the equipment.
The pump motor supports maximum voltage variations ± 10%.
- The section of conductors used must be enough to bear the intensity absorbed by the
unit (see nameplate on the motor).
- The ground wire will be connected to the metal parts of the equipment that must not be
under electrically tension.
- It is mandatory to install an electrical protection and control box where all the elements
Distance between valves and other obstacles

Minimum of 1 meter to the

To allow a proper ventilation:
The distance between the
fan guard and the wall
should be minimum of 2.5
times the fan diameter.
