6.4 MAINTENANCE PRODUCT CIRCUIT
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
: Danger of contact with toxic or corrosive fluids .
Maintenance of the pump's product circuit must be carried out periodically to ensure optimum perfor-
mance and the necessary safety conditions, as described below:
6.4.1
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, 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.
6.4.1a
To stop the pump, only act on the air supply: close the ball valve and the 3-way valve. Close the upstream
3-way safety valve,
discharge the residual pressure of the pump's pneumatic system and fit the
safety interlock.
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).
6.4.1b Disconnect the suction and delivery pipes of the pump fluid.
6.4.1c 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.
6.4.1d
Use the relevant Spare Parts table for the pump disassembly and reassembly sequence to access the
internal parts of the treated operations.
