2.4 Safety systems
Several safety systems have been conceived during the diaphragm pump design and manufacture to
safeguard the operator, in compliance with pr EN 12621 Directive about paint.
SAFETY VALVE
A 8 bar calibrated safety valve is installed to ensure the pump working pressure does not exceed the
limits inside the feeding circuit.
If the calibration pressure is exceeded, the valve opens by releasing the excess of air.
WARNING
DO NOT REMOVE THE VALVE PLASTIC PROTECTION. ANY TAMPERING WITH COULD BE
DANGEROUS FOR THE OPERATOR AND COMPROMISE THE EQUIPMENT GOOD WORKING.
THREE-WAY VALVE
In case of anomalies during working, turn 90° the three-way valve lever. In this way the air supply will
be interrupted and the residual pressure inside the pump will be released.
