OPERATING MANUAL
4.3.2 OPERATION WITHOUT FLUID
Avoid running the pump sucking air, without uid inside. The air, combined with the
vapour of ammable uids, can generate internal areas with an explosion hazard.
Periodically check that the pump is working regularly, paying special attention to presence
of air in the pumped uid, which may be caused by a breakage in the pump.
Avoid operating the pump with damaged diaphragms.
4.3.3 MAXIMUM SURFACE TEMPERATURE
The maximum surface temperature of the pump depends on the temperature of the
pumped uid, that must not exceed the values indicated in the section "Technical Data".
4.3.4 MAXIMUM SURFACE TEMPERATURE EXOTHERMIC REACTIONS
Fluids incompatible with the pump’s materials or particularly reactive mixtures of products
with several components may cause exothermic reactions and develop dangerous
temperatures or pressure.
4.3.5 CONNECTION PIPES
Connection cables must be made of conductive material and properly grounded.
4.3.6 PUMP PROTECTION
If the pumping uids contain solid particles, install a lter on the intake circuit. This
prevents particles, that are large enough to damage the internal parts of the pump, from
entering. Refer to the paragraph Technical Data to verify the maximum size of solids that
can be pumped.
Keep the metal surfaces clean. Electric conductivity of the surfaces is essential for explosion
protection.
Frequently clean the equipment so as to prevent residue of insulating substances from
accumulating.
Do not use rusted parts or metal tools that may cause sparks of a mechanical origin inside
the explosion hazard area.

B_04006
Double diaphragm pump - operating principle
The double diaphragm pump is driven with compressed air.
Two diaphragms (A) are mechanically connected to each other by means of a shaft (B).
Each diaphragm generates two chambers: pumping chamber (P) and motor chamber (M).
A pneumatic distributor alternately supplies compressed air into one of the driving
chambers (M), thus producing the diaphragms movement and consequently causing one
of the pumping chambers (P) to empty (as a result of volume decrease), while at the same
time the other chamber (P) sucks the uid in (as a result of volume increase). A series of four
check valves (C) prevents the liquid from owing back, thus producing the suction and
delivery phases in each pumping chamber, and generating the pumping e ect.
The ZIP models are equipped with an internal safety valve that opens when the maximum
allowed value of air pressure supply is exceeded.
WARNING
Overpressure!
Risk of injury from bursting components.
Never change the safety valve setting.

7.1 OPERATION
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.
7.2 ENDING WORK
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.
7.3 STORAGE OVER LONGER PERIODS OF TIME
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.
