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
STOPPING THE PUMP FOR MAINTENANCE TANKS
• Stop the air supply.
• Make sure for your safety that the air valve is closed.
• Turn off the air compressor, or close the valve on the air supply side of
the auxiliary equipment.
• Close the discharge valve and the suction valve. Open inlet and outlet
drain valves.
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 mm
• 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.
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.
