by installing a cover in appropriate material, which, in case of serious loss, protects the environment
and operators from the projection of dangerous substances.
9.
The horizontal length (S) of the suction pipe must be smaller as possible. In the case of high viscosity
fluids, increase the suction pipe diameter.
10.
Slope the suction pipe towards the pump, to prevent the formation of air locks in the line which
would affect the running time of pump.
Notes
Install wide and rigid filtering separator in case where the fluid suction system creates the conditions for
generating vortices or reels.
Fluids having a viscosity different from those of water:
•
DN Discharge Piping ≥ DN Connection;
•
DN Suction Piping must be greater than DN Connection.
FURTHERMORE
•
Ensure proper drainage of fluid which may emerge of the pump;
•
fix the pump using all the available locking holes, the support points
must be leveled
(the pump must
be fix to a foundation before starting), a slope of 10% or less is allowed;
•
arrange enough space around the pump for operator to move around;
•
arrange free space above the pump for lifting;
•
inform the presence of aggressive fluid with suitable colored labels in accordance with the related
standards;
•
do not install the pump near heat source;
•
do not install pump in places with the risk of falling solids and/or fluids;
•
do not install the pump close to fixed workshop or at places with high human traffic;
•
install additional protection shield for the pump or operator as appropriate;
• WARNING
: In the event of diaphragm failure, the fluid may contaminate the pneumatic
circuit.

400 and 650 are equipped with a conveyed air exhaust, in order to convey
the air exhaust in a pipe up to a safe area;
•
install a spare equivalent pump in parallel to prevent undesirable arrests of the process;
•
if the pump is made from conductive materials and is suitable for flammable products and is
installed in an explosive atmosphere, the pump fluid chamber must be equipped with suitable
grounding cable:
DANGER OF EXPLOSION AND/OR FIRE;
• WARNING
: The pumps installed in an explosive atmosphere must always be grounded to a
suitable electrical ground. Lack of grounding or incorrect grounding will violate the
requirements for safety and protection against risk of explosion;
•
only use the
3 way valve
on the air supply for starting and stopping the pump.
IT IS FORBIDDEN TO
STOP THE PUMP THROUGH THE TWO-WAY VALVE ON THE DISCHARGE PIPE AND/OR THE SUCTION PIPE;
• WARNING:
USE THE PRESSURE REGULATOR AND THE NEEDLE VALE (ON THE SIR SUPPLY) TO
ADAPT THE CHARACTERISTICS OF THE PUMP TO THE RATED POINT.
