GHIBLI 10:1 PNEUMATIC WASHING PUMP
REV.
02 - 06/2021 - Cod. 150186
CLEANING AT THE END OF
THE WORK
ROUTINE MAINTENANCE
•
Close the water supply (
L1
)
•
Drain the water from the pumping circuit by pressing the
spraying nozzle (
L2
)
•
Shut off the compressed air supply to the pump (
L3
)
•
Discharge the residual pressure present inside the pump.
•
In case of long activity, the operations of sucking and leaving
light mineral oil inside the pumping element are suggested.
• Daily check (
and every time the pump is operated after a
long storage
) the packing nut (
M1
) is not loosened, causing
otherwise the coming out of the product.
To tighten the packing nut use a metal rod
(M2)
with a
diameter of 6 mm (
see the illustration
). The packing nut must
be tightened so as to avoid the seizure of the pumping piston
and the eccesive wear of sealing gaskets.
In case of persistent coming out of product, provide for the
replacement of the upper sealing gaskets (
see on page 13
).
• Keep the cup (
M 3
) that covers the packing ring nut filled
with lubricating liquid in order to prevent the product from
drying on the piston rod.
• Check periodically the air supply to the pump. Ensure the
air is always clean and lubricated.
Always close the compressed air supply and
release the pressure in the plant before performing
any check or maintenance of the pump.
