Installation
The standard version pumps must be installed with the rotor axis in the vertical position and with the base
under the pump.
The 50, 65 and 80 models can be installed in horizontal position, using the appropriate support feet, which
are supplied on request.
Install the pump as close as possible to the suction source (with consideration given to the NPSH value).
Provide space around the pump for motor ventilation, to allow for checking of shaft rotation, for filling and
draining the pump and to allow for collection of the liquid to be removed (especially for draining liquids which
are harmful or have to be removed at temperatures higher than 60°C).
Make sure prolonged accidental leakage of liquid does not cause damage to persons or property.
Leakage may develop as a result of surge pressure or water hammer, erroneous operations (such as failing
to close a plug or valve) or other functional disorders. Allow for the possibility of channelling away any leaked
liquid or for an automatic drainage system against flooding.
Mount the pump on a flat horizontal surface (using a level gauge) such as a solid cement base or a rigid
supporting structure in metal. To ensure stability, insert, if necessary, small pieces of calibrated metal plate
next to the 4 anchoring screws.
Connecting the motor
The pumps are designed for use with standard electric motors with (IEC 34-7) IM V1 construction form and
dimensions and output ratings in accordance with IEC 72.
If a pump is supplied without the motor, check the rated power and rpm indicated on the name plate and
technical data given in the data sheet.
ATTENTION: the motors must have two lifting points in diametrically opposite positions for vertical lifting with
the shaft end downwards.
Before installation clean the motor shaft extension, the key and contact surfaces of the flanges to remove any
protective paint, dirt or oxidation. Lubricate the motor shaft extension with a graphite base, drip free, anti-
friction product.
Do not use oil as it can harm the mechanical seal below.
With the pump in the vertical position, insert the motor shaft in the coupling, aligning the key with the key slot
and resting the motor flange on the lantern flange.
Turn the motor, adjusting the position of the terminal box as required and aligning the holes on the flanges.
ATTENTION: The 4 flange screws with nut must be uniformly tightened with alternated crossover tightening
procedure in diametrically opposite positions.
Before and after tightening the screws, make sure the coupling with pump shaft and motor shaft can be
freely turned by hand (remove and then replace the guard).
ATTENTION: for removing or replacing the motor

Pipes

Provide a diameter assuring a liquid flow velocity not higher than 1.5 m/s for suction, and 3 m/s for delivery.
The pipe diameters must never be smaller than the pump connection ports.
The arrows on the pump casing indicate the inlet (suction) and outlet (delivery) ports.
