5. TRANSPORTATION AND HANDLING
The product is packed to maintain the content intact.
During transportation avoid to stack excessive weights.
Ensure that during the transportation the box cannot
move.
It is not necessary to use any special vehicle to
transport the packaged device.
The transport vehicles must comply, for the weight and
dimensions, with the chosen product (see technical
catalogue dimensions and weights).
5.1. Handling
Handle with care, the packages must not receive
impacts.
Avoid to impact onto the package materials that could
damage the pump.
If the weight exceeds 25 Kg the package must be
handled by two person at the same time.
Raise and transport the pump and pump-motor unit
(without packaging) as indicated in fig. 1, (Only for
MXV 50, before moving the pump, fix the clamps
(32.78) with the screws (32.80) to the flange (32.70)).
Raise the pump-motor unit slowly (fig.1c), making sure
it does not move from side to side in an uncontrolled
way, to avoid the risk of imbalance and tipping up. For
horizontal raising, brace the pump in a sling close to
the centre of gravity.

6. INSTALLATION
6.1. Dimensions
For the dimensions of the device (see technical
catalogue).
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...).
The place where the device will be installed must fulfill
the requirements in the paragraph 3.2.
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
The MXV-B, MXV standard version pumps must be
installed with the rotor axis in the vertical position and
with the base under the pump.
The pumps 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 channeling 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.
6.5. Connecting
MXV(L)4)
The MXV(L), MXV(L)4 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 diametricalIy opposite positions for vertical lifting
with the shaft end downwards (fig.1 b)
Before installation clean the motor shaft extension, the
key and contact surfaces of the flanges to remove any
protective paint, dirt or oxydation.
