5.1 COMMISSIONING AND OPERATION
The start-up and commissioning of the pump is reserved for trained and authorised Installers, who know
and follow the Original Instructions.
The user must always use fluids that are compatible with the original design conditions of the pump itself
and the ATEX marking affixed.
CAUTION
: risk of damaging the pump and product leakage and/or explosion.
it is forbidden to use the pump with fluids that are not compatible with the construction materials of the
components or in an environment where there are incompatible fluids and atmospheres.
Proceed as follows to commission the pump:
Pump start-up requirements
• Sampling tank with constant fluid level;
• Pump fluid compatible with chemical and temperature characteristics of the pump materials and the
affixed ATEX marking;
•
Suction and discharge circuit in serviceable condition and maintenance-free system;
5.1.1
Open the product sectioning valves of the suction and delivery pipes.
CAUTION
: risk of premature wear and/or diaphragm breakage.
It is forbidden to start pump operation with the product valves (suction and discharge) closed or shuttered.
5.1.2
Open the 3-way pneumatic valve to supply the installed pilot valve; the pilot valve installed upstream of the
pump (pneumatic oscillator, or 2/3-way valve for remote piloting from PLC), will start to supply the pump and
begin to operate.
5.1.3
Check and adjust the air pressure on the mains (while the pump is running): MIN 2 bar MAX 8 bar.
CAUTION
risk of standstill and/or early wear and/or diaphragm breakage.
With pressures below 2 bar (when the pump is running) the pump may come to a STANDSTILL, with
pressures above the MAXIMUM threshold (Max 8 bar) there may be failures and leakage ofthe pressur-
ised product and/or breakage of the pump.
