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 con-
tainers. 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 re-
lease 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)
.
