4.3 POSITIONING AND INSTALLATION
Installation operations are reserved for qualified and authorised Installation Technicians, equipped with suit
-
able Personal Protective Equipment (PPE), who are acquainted and comply with the contents of this Man-
ual. Since an endless variety of products and chemical compositions exists, the user is presumed to have
the best knowledge of their compatibility and reaction with the pump’s construction materials. Before using
and installing the pump, all necessary checks and tests must be performed with great care to avoid even the
slightest risk, an event that the Manufacturer cannot foresee and for which he cannot be held responsible.
General installation requirements
•
Adequate space to allow future maintenance;
•
Installation of the pump with horizontal axis;
• Mounting on rigid supports (ceiling or floor) with flatness (0.1 mm);
• With negative head for fluids with Max density up to 5,000 Cps at 20°C and a Max specific weight of 1.4 Kg/l;
• Installations with positive head for fluids with Max density up to 20,000 Cps at 20°C;
•
Positioning near the point of collection (max 10 times the suction diameter);
•
Suction inlet away from vortices;
•
Earthing the pump for installations in a potentially explosive environment;
•
Pneumatic circuit supply with dried, unlubricated air;
•
Installation of shut-off valve, 3-way valve and non-return valve on the air supply.
4.3.1
Position the pump with the axis horizontal at the place of installation, as close as possible to the point of
collection, aligning it with the suction and delivery ducts.
NOTE
The product delivery manifold must always be positioned in the upper area;
the arrows on the pump
casing must always be facing up
.
4.3.2
Provide for the tightening on rigid supports (to ceiling or floor with suitable flatness 0.1 mm) on feet with
appropriate washers and bolts. If necessary, provide suitable anti-vibration feet
(DEBEM catalogue)
.
CAUTION
: danger of explosion
ATEX M2 pumps must be installed in a low-impact risk environment.
4.3.3
If the pump is made of conductive material (CONDUCT design), and suitable for pumping permissible
flammable fluids, a suitable earthing cable must be installed on each pump body;
danger of explosion
and/or fire due to electrostatic currents.
CAUTION
: danger of explosion
The pump must always be earthed, independently of other parts connected to it. Failure to earth or incor-
rect earthing will invalidate the safety and explosion protection requirements.
Pump positioning is thus completed.
