WARNING
AIR CONNECTION
To ensure that the air supply is sufficient to meet the demand of the pump,
the diameter of the pipe must be equal to the diameter of the supply port of
the pump. Choose auxiliary air treatment equipment and fittings with
sufficient airflow to exceed the air consumption of the pump. In addition,
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
22 and 115 psi (1,5 and 8 bar), Hytrel
control flow. For the performance characteristics of the pump see the capacity curve shown on page 6.
STOPPING THE PUMP
• Close the inlet valve of the pump.
• Open the air valve of the pump, turn on the pump and flush the remaining fluid.
• Close the discharge valve on the discharge side, then begin to slowly open the drain valve and discharge pressure fluid.
• After ensuring that the pump was turned off and the pressure was released, fully open and close the regulator valve and drain valve of the pump.
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

GROUND WIRE
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.

The use of a coupler to connect the hoses aids future operation and
maintenance tasks.
• 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.
