WORKING PRINCIPLE

VEGA 23:1 pump is a pneumatic pump 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 pump is essentially composed of an air motor and a structure
known as “Product Pumping Unit”, or simply the “Pumping Unit”.
In the pneumatic motor, the compressed air causes the vertical
reciprocating movement of the motor piston; this movement is
transmitted through a connecting rod to the product pumping piston.
This allows the pump to suck the product and to feed it towards
the outlet.
The ratio 23:1 means that the outlet pressure of the product is 23

times higher than the pump feed air pressure.
The unit comes complete with a transportation trolley, a high­pressure product filter, an air supply regulator for the pump, a
product suction tube (complete with filter) and a recirculation tube.
Our spray guns are tested and controlled in our factory and are
derivered to the customer in perfect working conditions.
For this rason, in order not to alter the characteristics of these
units, it is advisable to carefully read these instructions and to
follow them accordingly.

ACCORDING TO THE PRODUCT

• At this point the unit is ready. Should water paints be used,
it is advisable to wash with soap water and then with clean
water, besides the washing with cleaning liquid.

PREPARATION OF THE PAINT

• Make sure that the product is suitable to be sprayed.

• Duly mix and filter the product before use. We recommend the
use of LARIUS METEX filters with fine-mesh (Rif. 214) or large
mesh (Rif. 215).

Make sure that the product is suitable to be
used with the materials employed for the unit
manufacturing. For this purpose, refer to the
product supplier.

• Rotate clockwise the pressure adjustment knob (F10) so that
the pump starts to work.

• When the product has been duly mixed, the product will flow
from the recirculation hose. (F2)

If the product does not flow, this means it is too thick and it

is necessary to dilute it again until a correct flow is achieved.
Let the product flow for a short time. At this point, the machine
is ready to work.

OPERATION

F10

PRODUCT PREPARATION

• Make sure that the product and the thinner are suitable to
be sprayed. Make sure that the thinner is suitable to be used
with the product to be sprayed. Make sure that the product
has been duly filtered and mixed.

NOZZLE AND FILTERS

• The nozzle and the filter shall be suitable for the gun, accor­ding to the product to be sprayed and to the operation to be
carried out (refer to the assembly tables and instructions).

• This table is for indication only. The adapatability of a certain
product to a determined nozzle changes according to different
aspects. If previous experiences are lacking, a practical test
is always necessary. A nozzle, which has been duly chosen,
will give as result a neat jet without pulsations and gives a
perfect praying of the product.

• An inconstant spray, slightly marked on the sides, might
indicate a too low pressure. If the maximum pressure has
already been reached, it is then necessary to choose a smaller
nozzle. With the exclusion of some products, which can be
atomized at high pressures only, it is advisable not to exceed
the value of 140-170 Atm (high pressure could cause mist).

• Considering an equal speed of application, a

nozzle with a spraying angle of 20° lays down a
film having a thickness which is averagely double
in respect to the one which can be obtained with
the same nozzle with an angle of 60°.

• An excessive diameter of the angle could result
in an anomalous pressure drop.

• When ordering a nozzle, choose accurately the
reference number on the list of the nozzles.

START SPRAYING OPERATIONS

• Use the equipment only after having completed all the
adjustment operations described in the previous paragraph.

Before using the equipment, check all the
connection fittings on the various components
(pump, flexible hose, gun, etc.)

• Use the provided lubricant (G1) (rif. 16325) in order to make

the sliding of the piston easier inside the sealing pack and
interpose oil to air.

G1

Daily check that the ring nut is covered with hydrau­lic oil (rif. 16325); the oil improves the sliding of
the piston and prevent the product, coming out
from sealing gaskets, to dry once the equipment
is stopped.

• Fix the spraying nozzle on the gun, choosing the suitable
nozzle according to the characteristics of the product to be
used and the kind of operation to be performed.

Plunge the suction hose (G1) and the recircu­lation hose (G2) in the product container (G3).

G1

G2

G3

• Open the recirculation tap.

• When the air tap (G4) is closed, make the air flow from the

compressed air supply.

Check on the pressure gauge (G5) that the pressure does not

exceed 2-3 Atm [adjust it with the knob (G6) of the regulator].

With an empty pump, a higher pressure might
cause a quick and violent movement of the piston,
which could be dangerous. Beside this, starting
with the max pressure (6-8 bar) the pump will not
be able to fill the chamber considering the high
speed of the cycle.

• Open the air tap (G4).
