6.4 PRODUCT CIRCUIT MAINTENANCE
This operation is reserved for trained and qualied 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 uids.
The maintenance of the product circuit of the pump must be carried out periodically to ensure an optimal
performance and the necessary safety conditions, operating as described below.
PUMP DISASSEMBLY
To carry out the product circuit maintenance, it is necessary to disassemble the pump as follows:
Safety requirements for 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 and decontaminated (according to the pumped liquid);
• 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.
To stop the pump, only operate on the air supply: close the ball valve and the 3-way sectioning valve. Close the
upstream 3-way safety valve, discharge the residual pressure from the pneumatic system of the
pump and place the safety interlock.
CAUTION: risk of internal back-pressures and projection of components during disassembly.
In severe conditions (incorrect installations and/or stops and/or in stall conditions), residual pressures inside
the pump can be generated which are not discharged. 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).
Disconnect the suction and delivery pipes of the pump uid.
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.
Use the relevant Spare Parts table for the pump disassembly and reassembly sequence to access the internal parts
of the treated operations.
