4.3.4h
If used for drum suction (not below head), the submersed end of the intake hose must be provided with
a diagonally cut fixing to prevent it from adhering to the drum bottom.
4.3.4i
In installations where the presence of solid particulate is foreseen, install a suitably oversized strainer
(which does not cause pressure drops) on the suction inlet, with a surface area of 2.5 / 3 times the area
of the suction pipe and passages smaller than the particulate allowed by the pump model being installed.
CAUTION
: risk of pump damage.
It is
forbidden to install the pump in the absence of a suitable correctly sized strainer.
Check that there are or can be no solid parts of large size or harmful form in the treated fluid and that
there are no restrictions in the pump inlet or outlet to avoid cavitation and membrane stress respectively.
4.3.4j
In installations in a potentially explosive environment with the possible presence of suspended solid
parts in the fluid, it is essential to install a correctly sized suction strainer to ensure that the pump oper
-
ates in accordance with the safety requirements set out in the marking.
WARNING
: risk of damage to the pump and loss of marking requirements
It is
forbidden to install the pump in the absence of a suitable correctly sized strainer.
Provide for periodic checks and maintenance of the installed strainer and of the suction and delivery
ducts in order to maintain and ensure the correct operation of the pump required by the marking for
operation in a potentially explosive environment.
The product circuit connection is thus completed.
