If the unit is to be used in a food environment, support
plates that allow the unit to be lifted for easier cleaning
are recommended.
Allow, if possible, a clear space of approximately 50 cm
on each side of the motor-driven pump unit (overall
dimensions) to facilitate cleaning and give access if
necessary to the pump, reduction gear and motor faste-
ning nuts. In all cases, the dimensions around the motor-
driven pump unit must be designed to give the space
required for dismantling the pump (if the need arises,
use the values given on the overall dimension drawing).
For staff and equipment protection, the frame includes a
ground connection point that should be used.
2.5.2 ALIGNMENT OF THE MOTOR/PUMP OR
REDUCTION GEAR/PUMP SHAFTS
NEVER START A UNIT IF THE COUPLING ALIGN-
MENT IS INCORRECT. THIS IS A CONDITION OF OUR
GUARANTEE.
REMINDER :
Coupling must never be used to compensate for a mis-
alignment.
To control the alignment between the coupling and the
shaft, use a straight-edge for concentricity and thickness
gauges for angular misalignment (see instructions of the
coupling for authorised values).
The 3 figures below show in detail the operation and the
possible defects :
Controlling the alignment at each stage of the installation
is important to be sure that none of these stages have
generated stresses on the unit or the pump :
• after fastening on the foundations.
• after fastening the pipes.
• after the pump has been operated at the normal
operating temperature.
Where the pumps are supplied assembled as a unit, the
motor and pump shafts have been perfectly aligned in
the factory before delivery, but they must be systemati-
cally controlled on acceptance at the site and realigned
if necessary.
To do this, do not modify the wedging of the various
parts, but check the flatness of the support surface and
use the adjustable foot to clear the frame of stresses that
could affect it.
2.5.3 ELECTIC MOTORS
Check the compatibility of the instructions on the motor
with the supply voltage.
Follow the wiring diagram, use wiring that is appropriate
for the power and be particularly careful about the
contacts which must be well tightened.
The motors should be protected with circuit breakers
and suitable fuses. Connect the regulatory electrical
grounding.
