Sirio pumps are pneumatic pumps for high pressure painting
without the use of compressed air (AIRLESS). The stainless steel
version is particularly suitable for use with water-based paints.
The Sirio pump is essentially comprised of an air motor and
a structure known as the “Material Pumping Unit”, or simply
the “Pumping Unit”.
In the pneumatic motor, compressed air causes the vertical
reciprocating movement of the motor piston; this movement
is transmitted through a connecting rod to the material pum-
ping piston.
This allows for the material to be aspirated and pushed towards
the outlet. The unit comes complete with a transportation
trolley, a high-pressure material filter, an air supply regulator
for the pump, a material suction tube (complete with filter)
and a recirculation tube.
The ratio (27:1-30:1-32:1-45:1) means that the outlet pressure
of material is (27-30-32-45) times higher than the pump feed
air pressure.

left inside the equipment.
• Close the air passage valve for pump feed.
• Point the spray gun at the tank of the solvent and press
the trigger so as to recover the clean solvent left inside
the pump.
• Remove the nozzle from the spray gun (Do not forget to
clean it using a solvent!).
• Dip the suction hose into the tank of the washing solvent
(ensure it is compatibile with the product being used).
• Insert the recirculating hose into a container (a metal con-
tainer is recommended).
• Open the recirculating cock.
• Open the air passage valve in order to start up the pump.
• Close the recirculating cock as soon as a clean solvent

In case of long storage, we recommend you to suck and to leave
light mineral oil inside the pumping group and the flexible hose.
• In this case, please follow the washing procedure described
on page 8 before using the tooling.
Store possible dangerous fluids in proper
containers. Their disposal must be performed
in accordance with the regulations in force
about the industrial waste goods.
GWORKING
• Use the machine after carrying out all the setting-up ope-
rations described in the previous paragraph.
Check all the fittings for connection of the
different components (pump, flexible hose,
spray gun, etc.) before using the equipment.
• Use the supplied lubricant (G1 - ref. 16325)
to facilitate the sliding of the piston inside the seal packing
and to interpose the oil within the air.
At the start of each working day, make sure that the
ring nut is filled with hydraulic oil (ref. 16325); the
oil facilitates the sliding of the piston and prevents
any material which may have leaked out of the seals
from drying once the equipment has been shut off.
• Fix the atomization nozzle on the spray gun. Select the
right nozzle according to the characteristics of the material
to be used and to the type of work to be performed.
• Dip the suction and recirculating pipes into the tank of the
product.
• Open the recirculating cock.
• Set the pump feed pressure at about 3-4 bar and open
the air passage valve.
• Allow the product to circulate for a few seconds. Then
close the recirculating cock. The pump will keep on working
until the high pressure flexible hose is full of product up
to the spray gun. Then the pump will stop automatically.
• Increase pump feed pressure so as to reach a pressure
value to guarantee a good atomization of the product.
• An irregular and marked spray on the sides indicates a
low working pressure. On the contrary, a too high pressure
causes a high fog (“overspray”) and waste of product.
• In order to avoid overthick ness of paint, let the gun advance

IROUTINE MAINTENANCE
Always close the compressed air supply and re-
lease the pressure in the plant before performing
any check or maintenance of the pump.
RING NUT CHECK
• Check periodically (and every time the pump is operated
after a long storage) the packing nut is not loosened, cau-
sing otherwise the coming out of the product.
To tighten the packing nut (I1) use wrench supplied
(I2). The packing nut must be tightened so as to avoid
wastes of product, but not excessively to avoid the
seizure of the pumping piston and the wear of seals.
In case of persistent coming out of product, replace
the seals.
MATERIAL SUCTION FILTER
• Remove and clean the material suction filter (I3).
HIGH PRESSURE FILTER CLEANING
• Remove and clean the high pressure filter for material
outlet (I4).
• Check periodically the air supply to the pump. Ensure the
air is always clean and lubricated.
At the start of each working day, make sure that the
ring (I1) nut is filled with hydraulic oil (ref. 16340); the
oil facilitates the sliding of the piston and prevents
any material which may have leaked out of the seals
from drying once the equipment has been shut off.
