6.2 EXTERNAL CLEANING AND TIGHTNESS CHECK
This operation is reserved for trained and qualified Mechanical Servicemen, equipped with suitable Per-
sonal Protective Equipment (PPE); see the Technical and Safety Data Sheets of the treated liquid.
CAUTION
: risk of contact with toxic or corrosive fluids.
The external cleaning and tightness check of the suction and delivery circuit of the pump must be carried
out periodically following the procedures described below.
6.2.1
EXTERNAL CLEANING OF THE PUMP
The pump must be cleaned externally periodically every 500 hours of operation to allow visual inspections and
safe operations. The presence of dust and/or deposits on the external surfaces of the pump can negatively
affect process temperatures. In environments with a potentially explosive atmosphere, it can even com-
promise the safety envisaged by the marking.
CAUTION
: risk of overheating and, in environments with a potentially explosive atmosphere,
risk of fire/explosion.
In environments with a potentially explosive atmosphere, it can even compromise safety, causing over-
heating and/or flammability of the dust.
Safety requirements before starting the operation:
• Pump stopped with air supply disconnected and interlocked and residual pressure discharged;
• Closed suction and delivery valves;
• Suction and delivery pump and circuits cooled.
Proceed as follows to clean the outside of the pump:
6.2.1a
Remove dust deposits from the external surfaces of the pump using a disposable cloth dampened with a suitable
neutral detergent.
CAUTION
:
risk of damage and/or fire.
Do not use detergents that are not compatible with the construction materials of the pump, solvents or
flammable substances.
6.2.1b
Remove dust deposits from the external surfaces of the suction and delivery pipes near the pump using disposable
cloths dampened with a suitable detergent (compatible with the construction materials of the pump).
6.2.1c
Check that the residual risk warning labels are clearly visible and legible; otherwise, replace them. Remove any
tools and cloths used from the pump.
The external cleaning of the pump is completed.
