Use suitable means for lifting and transporting the pump / electricpump.
Before executing any operation, turn off the power and prevent it from being reconnected.
For installation example refer to

Verify that the data shown on the plate, and in particular, power, frequency, voltage, absorbed current, are compatible
with the characteristics of the electric line or current generator available. In particular, the voltage of the line voltage can
have a variance of ± 5% from the nominal voltage value on the plate.
Verify that the protection and insulation grade indicated on the plate are compatible with the environmental conditions.
Verify that the chemical/physical characteristics of the liquid to be moved correspond to those specified on the order.
Verify that the pump has not been exposed to the weather inclemency.
Verify the environmental conditions: SAER pumps can be installed in enclosed or, at any rate, protected areas, with
maximum ambient temperature of + 40 °C in a non-explosive atmosphere.
Contact the customer care in case of ambient tempe40°C or altitude over 1000m above sea level.
The connection to the water supply must be done in the respect of the local and national standards of the place where
the pump is installed.
Verify that the pump’s flow rate and head correspond to the required characteristics.
Before connecting the pipes to the relative openings, make sure that the rotating part of the pump turns freely and is not
hindered. In case of problems please contact our technical assistance servicing.

Prepare a concrete base for the complete set, and raise it, up to the required height (minimum 30 mm).
Make sure that the pump’s support surface is solid and even (so that it rests on all the feet) and that the load capacity of
the surface is adequate for the weight shown on the plate.
Verify that the surrounding area is sufficient for ventilation and allows movement in the case of maintenance.
Select suitables point and area of fixing: verify the prevention of possible vibrations to the surrounding structures.
Check that the strength of the concrete foundations is appropriate and complies with current relevant regulations.
It is recommended for the foundation base, a weight about five times major then the weight of the complete set.
The pump/electric pump must be installed as close as possible to the suction point of the liquid.
If you pump toxic or harmful liquids or at high temperatures, it is important to taken all necessary precautions to avoid
any loss and/or leakage that could cause damage to persons, animals, property or to he environment.

The pump maximum working pressure can’t be bigger than the PN pump nominal pressure.
Pipes must be suitable for the pump maximum working pressure.
The intake and delivery pipes must not transmit forces to the pumps/ electric pump due to their own weight and/or heat
expansion, at the risk of possible liquid leaks or breaking the pump. For this reason, the pipes must be supported by
anchorages and, if necessary, expansion joints must be inserted in the appropriate positions.
Pumps don’t have to transmit vibrations to the pipes, therefore insert anti-vibration couplings both in suction and delivery.
Install non return valve on the discharge side.
Install gate valve both in suction and discharge side.
The intake pipe must always be perfectly air tight and not positioned horizontally, but must always rise towards the pump. It is a good idea to
protect the pump by inserting a filter on the intake pipe; especially during the initial period of operation, the pipes release slags capable of
damaging the pump seals. The filter must have a mesh less than 2 mm and a free passage area of at least 3 times the section area of the
pipe so as to avoid excessive losses of head. To adjust the flow rate, it is a good idea to install a shutter on the delivery pipe.
The diameter of the pipe must be such that the speed of the liquid never exceeds 1,5 - 2 m/s at intake and 3 – 3,5 m/s at the delivery. In any
case, the diameter of the pipe must not be less than the diameter of the pump openings.
After having performed the controls listed, connect the pipelines to the pump.
