7.1 OPERATION
7.2 ENDING WORK
When storing the device for longer periods of time it is necessary to thoroughly clean it
and protect it from corrosion. Use a suitable preserving uid, according to the material of
the wetted parts of the pump.
Suction:
Make sure that the air pressure regulator knob is turned fully counterclockwise (0 bar
pressure).
Open the compressed air and material delivery valve, then increase the air pressure until
the pump starts. While the pump is priming, don’t exceed with the speed.
Return valve:
To facilitate the priming of the pump, open the return valve, if installed.
The return valve is strongly recommended in case of viscous materials or long pipes. Close
the return valve when the suction is nish.
Material delivery:
The pump supplies the material while the material delivery valve is open.
Change the air pressure with the air pressure regulator, in order to achieve the desired
amount respectively pressure of material.
Drawn in air:
In case air accidentally ows into the pump suction inlet, it is necessary to immediately
reduce the compressed air pressure to avoid the pump working at an excessive speed.
Stopping the pump:
To stop the pump, simply close the material delivery valve or any other device installed
(such as dispensing valves or guns) on the delivery line.
At the end of the Work close the air cuto valve. Relieve the pressure in the material line, by
opening the return valve (if installed) or the dispensing device (valve or spray gun).
Dealing with hardening liquids:
In case of hardening liquids such as 2-component mixed resins, the pump, and anything
connected to it, must be thoroughly ushed out at the end of working session with using a
solvent suitable for the type of resin being used. The solvent must be left inside the pump,
until its next use.
