SETTING UP
TYPICAL INSTALLATION
NOVA 20:1 EXT
pump can be installed on pneumatic double post
ram whit shovel plate (see the picture).
The double post ram allows to suck the product directly from
the drum and also to replace quickly the drum itself. The shovel
plate, fastened at the base of the pump, compresses the material
ensuring a constant flow of product. In addition, is protects the
material not yet sucked against powder, moisture and drying
caused by contract with air.
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.
WORKING
• Dip the material pumping hose into the product tank (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).
• 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.
• In case of difficult suction of the pump, slowly open the bleeder
valve and close it when some material comes out
• 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 or the delivery valve at the tank and drain
the product left inside the pump till the material to be used
has come out.
• 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.

Pos. Description
1 Double post ram for 200 litres drums
2 Shovel plate in cast iron complete with double gasket
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 20 time the inlet pressure of the pump feed air.
Therefore, it is extremely important to adjust the
value of the feed air pressure.
Check all the fittings for connection of the different
components
(pump, flexible hose, spray gun, etc.)
before using the equipment.
Always avoid pump idling: this operation could
damage the pneumatic motor and the seals.
I
CONNECTION TO THE FEED AIR
For pump feed use a hose with an internal diameter no lower
than 20 mm.
CONNECTION OF THE MATERIAL OUTLET HOSE
Connect the high pressure hose at the outlet of the pump.
It is recommended to tighten the fittings.
