NOVA 60:1
WORKING PRINCIPLE
NOVA pump 45:1 (or 60:1) is a pneumatic pump to be used in
the high pressure painting without air (Airless) or for transferring
of fluids in case of more stations of usage.
NOVA pump is essentially constituted of an air motor and a structure
called «material pumping group» or simply «pumping group».
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 pumping piston.
So doing the pump sucks the fluid and pushes it to the outlet.
The ratio 45:1 (o 60:1) means that the outlet pressure of fluid is
45 (o 60) times higher than the pump feed air pressure.
TECHNICAL DATA
Parts of the pump in contact with the material
Pumping group: galvanized carbon steel and cast iron or stainless
steel AISI 303 and 420B
Sealing balls: stainless steel AISI 420B
Gaskets: teflon or nitrile or delrin or vulkollan
Other parts of the pump
Support and cylinder for pneumatic motor: aluminium
Covering: sheet FE37
Motor piston and roller pushing mount: cast iron
Always observe these instructions carefully
when evaluating the product compatibility
and in case of disposal of some parts of the
pump no more usable, in order to meet the
environmental regulations on recycling process.

F
TYPICAL INSTALLATION
The NOVA pump is generally supplied on support for wall fastening
or on trolley or on double post ram.
For the correct fastening of the pump on other structures use
the 4 holes placed at the base of the pneumatic motor (see the
illustration for dimensions).
The machine is equipped with
an anti-freeze system
that allows it to
work even at very low temperatures. However, after a few
minutes of operation, the
upper metal outer surface
cools dramatically.
Avoid touching the area
indicated.
Contact of the skin with the
low-temperature area may
cause frostbite. Common working clothes and leather gloves
provide adequate protection.

• Make the compressed air flow into the pump. It is advisable to
adjust air pressure to minimum necessary for its continuous
working.
• When the product chamber is full, pump will start working and
stopping. Pump will start working again any time the trigger
of the spray gun is pressed or the delivery valve is open.
• The pump has been adjusted at our factory with light mineral
oil and a part of it could be left inside the pumping element.
Point the spray gun (H3) or the delivery valve at the tank (H4)
and drain the product left inside the pump till the material to
be used has come out.
Always avoid pump idling: this operation could
damage the pneumatic motor and the seals.
• In case of long inactivity during the use with the plant (for
example, all night long at the end of the working day), ensure
the product you are using can be left inside the pump and
the different pipes without drying.
In this case, it is enough to stop the air supply to the pump
and drain the residual pressure in the circuit acting on the
delivery valve or on the pump bleeder valve.

SETTING-UP
PUMP FASTENING ON THE HOIST
For the correct fastening of the pump on the ram, follow the
procedure described in the manual for use and maintenance of
the double post ram.
CONNECTION TO THE FEED AIR
For pump feed use a hose with an internal diameter no lower
than 20 mm.
H
WORKING
Install at the pump inlet an air pressure regulator
(it is suggested complete with condensate filter
and lubricator). The outlet pressure of the material
is 45 times (NOVA 45:1) or 60 times (NOVA 60:1)
the inlet pressure of the pump feed air. Therefore, it is extremely important to adjust the value of the feed air pressure.
CONNECTION OF THE MATERIAL OUTLET HOSE
Connect the high pressure hose at the outlet of the pump.
It is recommended to tighten the fittings.
Check all the fittings for connection of the dif-
ferent components (pump, flexible hose, spray
gun, etc.) before using the equipment.
• Dip the material pumping hose (H1) into the product tank
(H2) (if the pump is fixed on the double post ram, follow the
procedure described in the manual of use and maintenance
of the double post ram).

CLEANING AT THE END OF
THE WORK
By "cleaning at the end of the work" is meant the cleaning to carry
out in case of use with a different product or if a long period of
storage is foreseen.
• Stop the air supply to the pump.
• Dip the material pumping hose into the washing solvent
tank (check its chemical compatibility with the product being
used).
• Make compressed air flow into the pump. It is advisable to
adjust the air pressure to minimum necessary to its continuous
working.
• Point the spray gun or the delivery valve at a container and
drain all the product left inside the pump till a clean solvent
comes out.
• Now, stop the air supply to the pump and drain the residual
pressure.
• In case of long inactivity, the operations of sucking and leaving
light mineral oil inside the pumping element are suggested.
Store possible dangerous fluids in proper containers. Their disposal must be performed in
accordance with the regulations in force about
the industrial waste goods.
L
ROUTINE MAINTENANCE
Always close the compressed air supply and release the pressure in the plant before performing
any check or maintenance of the pump.
• Check periodically (and each time the pump is operated after
a long storage) the packing nut is not loosened, causing
otherwise the coming out of the product. To tighten the packing
nut, lift the wet cup (see illustration below).
Use the wrench supply (ref. 11504). The packing nut must be
tightened so as to avoid wastes of product, but not excessively
to provoke pumping piston seizure and seals wear. In case
of persistent coming out of product, replace the seals.
• To prevent the product from drying up on the piston rod, refill
the cup with lubricant (compatible with the product used).
• Check periodically the air supply to the pump. Ensure the
air is always clean and lubricated. In case of installation of
a lubricator on the air supply to the pump, it is advisable to
keep its cup full of a mixture of water and antifreeze liquid
(dilution ratio 4:1).

P DISASSEMBLY OF THE PUMPING GROUP
Always close the compressed air supply and
release the pressure in the plant before disassembling the pumping group. If the product being
used is toxic, it is suggested to follow the cleaning
procedure on page 8 to avoid the contact with the product
during the disassembling of the pumping element.
• Disconnect the suction pipe and the outlet tube of the product
from the pumping group.
• Unscrew the coupling sleeve so as to disconnect the pumping
group from the motor.
• Remove the nuts (O1) and take out the pumping group.
• Remove the wet cup (O2).

It is possible to increase the suction valve ball
stroke placing the stop ball pin (O6) on the upper
holes of the suction valve. This modification is
suggested in case of very viscous products. The
same operation can be performed on the piston rod.
• Extract the piston rod from the bottom.
• Disassemble the piston rod and replace the gaskets worn.
• Remove the upper gaskets, if necessary, to be replaced.
• For the correct reassembling see illustration and the exploded
view on page 18.
