8.1 DECOMMISSIONING AND WASHING FORM
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 handled)
.
In the event of long periods of inactivity or if leakages or operating anomalies are detected which could
affect the safety of the pump or the system on which it is installed, or at the "End of Life" of the mem-
branes, the pump must be taken out of service until the necessary safety conditions and optimum oper-
ation of the pump are restored.
WARNING :
danger of contact with toxic or corrosive fluids.
It is forbidden to use the pump in compromised conditions or with membranes that have reached the "End
of Life" as indicated by the Manufacturer;
danger of fluid leakage, danger of fire.
8.1.1
DECOMMISSIONING DUE TO INACTIVITY
Before decommissioning for long periods of inactivity, it is necessary to proceed as follows:
8.1.1a
Clean the external part of the pump using cloths dampened with suitable detergent (compatible with the
construction materials of the pump).
8.1.1b
Flush the inside of the pump (washing, decontamination or stripping depending on the fluid used) with a
suitable cleaning agent (compatible with the construction materials).
8.1.1c
Close the product suction and delivery on/off valves mounted on the pump.
8.1.1d
Close the air supply with the 3-way valve and relieve the residual pressure from the internal pneumatic
circuit of the pump after which the air supply at the network node should be disconnected.
CAUTION
: risk of internal back-pressures and projection of components during disassembly.
In abnormal conditions (incorrect installation and/or shutdown and/or standstill conditions), residual pressure,
which is not discharged, may be generated inside the pump. Before opening and disassembling the pump, it
is necessary to secure the pump casings with a suitable ratchet strap and wear suitable Personal Protective
Equipment (PPE).
8.1.1e
Indicate the “DECOMMISSIONING” status on the pump with a specific signal.
8.1.1f
If the pump is to be stored or returned to the manufacturer, it must be dismantled and emptied
as described
in section 8.1.2
.
8.1.2
DISASSEMBLING THE PUMP FROM THE WORKSTATION
To dismantle the pump from the workstation, proceed as follows:
Safety requirements before starting the operation:
•
Pump stopped with air supply disconnected and interlocked and residual pressure 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.
•
Closed product sectioning valves (suction and delivery);
•
Suction and delivery pump and circuits at ambient temperature.
8.1.2a
Disconnect the suction and delivery pipes of the pump fluid.
8.1.2b
Disconnect the compressed air supply pipes to the pump.
8.1.2c
Disassemble and remove the pump from the place of installation using suitable lifting equipment and
adequately drain the product circuit according to the treated product.
CAUTION
:
risk of leakage of the washing and/or contaminated liquid.
The pump is not self-draining, pay attention during handling and disassembly.
