OPERATING INSTRUCTIONS
THIS PUMP IS SELF-PRIMING
To prime it the first time, you must connect the air pump supply to a low pressure using the pressure regulators while keeping the outlet valve open.
When fluid begins to flow from the pump outlet, the pump is primed. For regulation of fluid pressure, the unit must be supplied with an air pressure
between 1,5 and 8 bar (20 and 120 psi). Adjust the discharge valve on the discharge side to control flow. For the performance characteristics of the
pump see the capacity curve.
STOPPING THE PUMP FOR MAINTENANCE TASKS
• Stop the air supply.
• Make sure for your safety that the air valve is closed.
• Close the discharge valve and the suction valve. Open inlet and outlet drain valves.
• Open the air valve of the pump, running bring on the pump and flushing the remaining fluid.
• Close the air valve.
• After ensuring that the pump was turned off and the pressure was released, pump is ready for its maintenance.

GROUNDING THE PUMP
When installing the pump, be sure to perform grounding in the specified
location.
Also connect ground wires for the auxiliary equipment and piping.
Use a grounding cable of at least 12 gauge (2.0 mm2).
If the pump you have purchased is valid for Atex, a specific Atex manual
will accompany this one. Read this manual before operating the pump.
If the unit is marked with the symbol
explosive atmospheres. Below this symbol, in the nameplate of the pump,
are indicated the areas for which the equipment is approved. You will also
find the maximum allowable surface temperature in the same plate.
WARNING
Connect grounding wires to the pump, piping and all other
equipment too.
When the pump operates ungrounded or with an incorrect
connection, friction between parts and abrasion caused by some
fluids that flow inside the pump, can generate static electricity.
Moreover, according to the type of fluid pump and the
installation environment (such as gases in the air or the type of
the surrounding facilities) static electricity can cause fire or
electric shock.
