OPERATING INSTRUCTIONS
THIS PUMP IS SELF-PRIMING
To prime the pump for the first time, connect the air supply to the pump at low pressure using the pressure regulator 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 (22 and 115 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, slowly turn on the pump and flush 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 a grounding wire to the pump, piping and all other
equipment.
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.
