OPERATION
• Immerse the material pumping hose in the product tank (
if the pump is secured on the pneumatic extrusion ram,
follow the procedure described in the pneumatic extrusion ram use and maintenance manual
).
• The pump is switched on (
and subsequently switched off
) by means of the pneumatic valve. Have compressed air
flow to the pump. Adjust air pressure to minimum value necessary for continuous operation.
• The pump will begin operation and will stop when the entire product chamber is full. The pump will re-start ope-
ration every time the dispensing valve opens.
• The pump has been tested at the factory with light mineral oil which may remain somewhat inside the pump.
Direct the dispensing valve against a container and drain all product left inside the pump until the material to be
used comes out.
• If long pauses during machine use are foreseen (
for example, all night at the end of a working day
), ensure that
the product you are using and different hoses can be left inside the pump without drying.
If this risk does not exist, then simply cut off pump air supply and discharge circuit pressure on the dispensing
valve or the pump bleed valve before an operating pause.
Check all connection fittings on the different components (pump, flexible hose, etc.) before using the machine.
Never operate the pump without a load. This could cause serious damage to the pneumatic motor and ruin
sealing gaskets.
