6.2 EXTERNAL CLEANING AND TIGHTNESS CHECK
This operation is reserved for trained and qualified maintenance technicians, equipped with appropriate
Personal Protective Equipment (PPE)
(see Technical and Safety Data Sheets of the liquid treated)
.
CAUTION
:
risk of contact with toxic or corrosive fluids.
External cleaning and checking the pump’s suction and discharge circuits for tightness must be carried
out periodically according to 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.
WARNING
: danger of overheating and in potentially explosive atmospheres fire/explosion hazard.
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 complete.
