6.5.2
REPLACEMENT OF THE COAXIAL PNEUMATIC INSERT for SCUBIC and
S
BOXER
All S
CUBIC and
S
BOXER
pumps accommodate a coaxial pneumaticinsert; the pneumatic insert must be replaced:
CAUTION
:
risk of contamination, injuries and/or harm to health.
Should the pump be returned to the Manufacturer or to an Authorised Assistance Centre, it must first be emp
-
tied of the product or any detergents.
If toxic, noxious or other types of health harming products have been used, the pump must be suitably treated
and washed before it is sent.
Safety requirements for the operation:
•
Pump removed from the workstation and residual pressure inside the air circuit discharged;
•
Pump with the external parts cleaned/washed;
•
Pump with internal product circuit washed, decontaminated and/or stripped (depending on the liquid being
pumped).
•
Pump with product circuit drained of the contaminated washing liquid.
6.5.2a
Disassemble the suction and delivery manifolds by removing the fastening elements.
6.5.2b
Disassemble the fixing screws and remove the pump casings.
6.5.2c
Remove the diaphragm locking cap of both circuits and remove the pump diaphragms.
6.5.2d
Disassemble the pneumatic insert by removing the fasteners.
6.5.2e
Clean the central and the diaphragms using a disposable clean cloth dampened with a suitable detergent
(for the construction material of the pump and the treated product).
CAUTION
: risk of damage and/or fire.
The use of cleaning agents that are incompatible with the pump materials, solvents or flammable sub
-
stances and/or pumping fluids is prohibited.
6.5.2f
Spread a layer of suitable grease (MOLYKOTE
®
PG21) on the housing holes of the pneumatic insert.
CAUTION
: danger of pump blocking.
Do not use any type of oil; the oil removes the grease and once discharged, it causes consequent block-
age due to lack of lubrication.

Replace the pneumatic insert and connection shaft with an Original Spare Part with the same character-
istics as the original (component materials).
