Air Connection; Stopping The Pump - Samson DF30 Manual De Uso

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,
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
• Close the inlet valve of the pump and 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 on the discharge side, then begin to slowly
open the drain valve and discharge pressure fluid.
• Open the air valve of the pump, turn on the pump and flush the
remaining 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.
• 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

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.

Air connection

peripheral air treatment equipment must be installed as close as possible
to the pump unit.
The use of a coupler to connect the hoses aids future operation and
maintenance tasks.
Operating instructions
regulation of fluid pressure, the unit must be supplied with an air pressure
between 43.5 and 100 psi (3 and 7 bar). Adjust the discharge valve on the
discharge side to control flow. For the performance characteristics of the
pump see the capacity curve shown on page 3.

Grounding the pump
• 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.
