ROUTINE MAINTENANCE
CONTROLLO DELLA GHIERA PREMIGUARNIZIONI
Always close the compressed air supply and
release the pressure in the plant before perfor-
ming any check or maintenance of the pump.
• Check periodically
(and each time the pump is operated
after a long downtime)
that the packing nut is not loosened,
causing otherwise the coming out of the product. To tighten
the packing nut, use the clamping wrench
(ref. 20144).
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)
.
